Harbor Freight Ghost 212cc

Posted by Jody Powell on 25th Aug 2022

I know there are a bunch of YouTube and Forum videos/write ups on the Predator 212cc Ghost engine, but none by me yet lol. We’ve had this engine on the dyno and done some tuning as well as a few part swaps. I’m not going to get into the topics the others used or the power it did/didnt make, however what I will get into is using one of our billet flywheels on this engine. As most of you know the Ghost is a Ducar style 212cc engine with a Chinese copy of a Briggs Animal slide carb, a slightly different cam profile, factory top plate and most importantly a 6000 RPM Rev limiting coil. This engine comes with your standard looking cast iron flywheel but it has one major difference from all the other cast iron flywheels. The timing key is cut at a different location because the rev limiting coil has a much different trigger point than the regular Predator or Clone coils do. This means that the Ghost rev limiting coil will not work with any of our current billet flywheels. In order to use an ARC billet flywheel on the Ghost 212cc engine you will need to change to a standard Predator, Clone or Honda coil. Just a reminder that if you do change to a standard Predator or Clone coil with an ARC billet flywheel, it will no longer be rev limited by the ignition. So a billet rod would also be in order. From what we have seen and heard the valve train can differ from one engine to another. Some may have 5mm stems and some may have 5.5mm stems. All will have 27/25mm heads and will be overall longer than other engine types on the market, so you will need to pull the valves out and measure the OD and length of the stems before ordering aftermarket valves. Here is a parts list of the billet and replacement parts for the Ghost 212cc engine… 

Billet Flywheels… 6619, 6689, 6602 

Predator/Clone coil… DJ-1260 

Billet Rod for Ghost piston… 6773

Billet Rods for Hemi Flattop piston… 6269, 6270, 6271

Hemi Flattop piston kit… DJ-1285PH

Cams… any cam for Honda/Clone/Hemi engine

Billet Sidecover… 6057 

Head Gasket… DJ-1310TP for .040” thick DJ-1310PH for .010” thick

Sidecover Gasket… DJ-1338

All of these parts can be found on our website at arcracing.com or through our sales/tech line at 800-521-3560.

What size bolt do I need for the Predator 212 Cc OHV Horizontal Shaft Gas Engine?  

I believe 5/16-24  

That is correct-strange isn't it!!!

maximu5 said: 5/16"-24 means the size of the bolt is 5/16" and the -24 means there are 24 threads per inch on the bolt so making it a fine thread bolt. On a normal 5/16" bolt there is 18 threads per inch making it a coarse thread. Click to expand...
toystory_4wd said: As far as the SAE/Metric thing goes- it's because the engine was optioned for the north american market. If you got a european engine, you'd have gotten a metric PTO shaft to go with your metric bolt size. Click to expand...

I also purchased a 212cc Predator engine to put on our Brute Cycle trike. When I put the clutch on the shaft and tried to thread the bolt in(also 5/16-24 from Lowes), it was first start to thread, then it got real hard. So I pulled it back out and left it for now. I didnt want to do any damage to the shaft. Could I have gotten the wrong bolt or is it hard to thread a new bolt in a new engine at first?

  • you had some gunk on the bolt that made it hard to hand thread
  • the bolt thread was knicked somewhere, which makes it a royal pain to hand thread
  • you cross threaded it (which is not very likely if you hand thread, only if you use an impact wrench or drill)

Get another bolt from a different source. Perhaps the bolt was an offshore product and not up to spec. Try a bolt from NAPA Auto Parts. If that bolt has the same results get a tap and run it into the hole gently to remove burrs or trash.

I can confirm the Predator 212cc uses 5/16 - 24 for the crank shaft and the 4 block mounting holes, the Predator 346cc and 420cc use 3/8" - 24 for cranks and 5/16" - 24 for the block mounting holes

I just used the same bolt that was on the old Briggs fun power 5hp and it fit .

Predator 224 vs 212 – What’s the Difference?

Harbor Freight is back with an upgrade for their famous 212cc Predator! But how much different is it for the 212cc and is it worth paying the extra $40 for? That’s what we will be looking through in this article. If you’re looking for the performance parts that will fit the new engine, check out our performance parts list for Predator 224

The most important difference is the displacement! Predator 224 has 12cc more displacement in comparison to Predator 212.

The 224cc Predator has a 3mm bigger stroke in comparison to the 212cc but uses the same sized bore, it makes about 0.1 hp more (max) power and about 0.5 to 1 ft/lbs more (max) torque in comparison to 212cc .

Another thing to note is that, unlike Predator 212 which came with two models, Hemi and Non-Hemi , the 224 cc engine only has 1 model (as of right now) which has a Non-Hemi head.

Engine Specs:

Predator 212 (Non-Hemi)

predator ghost engine shaft size

Predator 224

predator ghost engine shaft size

Note that the cover and manual of the Predator 212 says 8.1 ft-lbs torque, but that engine makes much more than that, you can check that mathematically, even if the max torque was at 3600 rpm it still only equates to 5.5 hp and we know from dyno tests that first of all the max power isn’t at 3600 and second, the power is around 6.5 hp.

In all likelihood, they haven’t mentioned the correct torque in the 212cc and are closer to real torque in 224cc, so even though the difference seems big and it will be noticeable but it won’t be as much as you might expect from the specs.

In terms of weight and dimensions, surprisingly the 212 cc is about 3 lb heavier than the 224cc. The dimensions are also slightly different, however, the engines are interchangeable for almost any application.

Let’s talk in more detail about the difference in the internals!

Air Intake, Exhaust & Carburetor

There is no difference in these parts. The 224 comes with the same Air-filter and muffler as the 212cc. The carburetor on 224cc is also identical to 212 cc carbs, with a non-adjustable air-fuel screw. For upgrades, you can use the VM22, its 26mm clone, or other 0.9″ carburetors for the best increase.

The headcover that the new engine comes with is the same as the 212cc non-Hemi headcover. You can swap it for other honda and honda clone head covers if you wish to.

The working of a 224 is the same as any other industrial engine, it uses a push rod and a rocker arm to move the valves up and down with the movement being timed with the camshaft.

The head is very similar to the non-Hemi and other honda clones, however, there are differences in comparison to the Hemi head, you can check the differences between the two in this article .

The rocker ratio is set the same as a Predator 212. The intake and exhaust ports both have got some sharp edges similar to the non-Hemi Predator 212 , you will need to work on porting for best performance gains.

The intake Valve is 27mm and the exhaust is 25mm on the 224cc. The valve stem is 5.5 mm. The honda clone valves will fit perfectly if you want to upgrade to stainless steel.

The valve springs that come stock are the same as predator 212, i.e, 10.8 lb springs that will float at about 5500 rpm. The maximum you can upgrade them to is 26 lbs without machining the valve pockets.

Rod & Piston

The 224cc comes with a dished piston similar to the 212 non-Hemi. Good news – the engine can use clone rods! No need for a separate rod like we had to in Predator 212.

Wrist Pin: .709″ Crankshaft Journal: 1.180″

If you’re doing a build you’ll likely switch to a billet rod. With the stock Piston, you can use an ARC 6773 rod (will require some block and cam clearance) or you can swap the dished piston with a flat piston and use the Wildcat 223 Rod and Piston sold by ECcarburetors (EC 8281)

Note: While choosing the rod and piston, maintain at least 0.030″ clearance.

The new engin e is coming with a plastic cam , this has raised some questions about the reliability and longevity especially for Engine builds. But the truth is that many manufacturers have been using it in small-block engines for a long time and the plastic cams hold just fine even at high RPM.

The cam will most likely not cause any issues, however, if you do wish to switch it up, the engine will take all the Honda/Clone cams.

Speed Governor

The mechanism of the governor’s work is pretty much the same, plastic governor gear which is geared with the rotation of the cam and the crankshaft that uses centrifugal force to expand the pins and push the ball in the governor gear to limit the speed.

The 224cc’s speed governor limits the engine to 3750 while the Predator 212’s limit it to 3600, out of the box you’ll likely see little to no gain in top speed.

They are placed in the exact same spot in both the engines, removal is also the same. You can check our step-by-step guide f o r governor removal if this is your first time working with these engines.

Top Speed & Acceleration

As stated above, the top speed is limited due to the governor. However, with the governor removed, you can expect a 1-2 mph difference with the bigger engine and the same minibike/go-kart setup.

Since the 224cc engine produces more torque you’ll get up to the top speed quicker with the 224 engine in comparison to the 212cc engine. There have already been several videos uploaded on YT related to speed comparison that you can check out.

Now the important question – Is it worth the extra $40? In comparison to the non-Hemi Predator 212, I would say definitely it is worth spending a little extra, due to its better build quality (manufactured by Ducar!), slightly better performance , and huge mod potential.

But in comparison to Predator 212 Hemi, the Hemi head has its own benefits like better porting and their rocker arms. The choice is for you to make, do you like the Hemi head more or would you like a more powerful non-Hemi?

If you’re still deciding on an Engine for your Go-kart or minibike then there are some other options to consider like Tillotson and Ducar Engines, check out our choice of best engines for Go-Kart and Minibike .

What type of Centrifugal clutch goes on the 224cc predator engine and if sow where can I find one?

They have the same shaft size as 212 predators so they use the same clutch or torque converter. You can check this article for the list of best clutches.

Will the Electric start kit from Amazon for a 212 fit the 224?

Same clutches as a 212 I belive it is a 5/8th inch clutch you can. Go with a 10 or a 12 tooth

It’s a 3/4 centrifugal Clutch

3/4 bought mine off of Amazon

Hi, I’m looking at this engine for for a replacement for my rototiller which has the HONDA GC160,, it’s 3 years old and probably has about 20 hours on it cause I use it a couple hours in spring and again at fall time, I was just running it Sunday to clear out the gas in bowl and all of a sudden engine stopped, I go to pull the cord and it spins over soooooo FREE, I’m a car mechanic so I pull plug ,, no compression, I put a wooden stick in plug hole and it’s not going up- down. I open it up and the rod broke off crank, the engine is spotless cause I’ve changed oil 5 times.

So do 212 billet parts non hemi fit 224 ? For example 212 billet parts onto 224 ?

I can’t find a 224 billet flywheel anywhere are they the same for the 212?

Yea it’s the same as 212, gx200, etc. ARC 6619 will fit.

This article has been extremely helpful in decipher these differences and has answered many questions ahead of making mods. Thanks for making it easier for the rest of us and sharing 🙂

My pleasure 🙂

New HF 212cc Predator Ghost "Racing" Engine

Has anyone heard about this new Go Kart specific engine from Harbor Freight? Not wanting one yet, unless to toy with, just curious to what everyone’s opinions on here is towards it. Retails $299.99 and an additional $149.99 for air filter, exhaust, fuel pump etc. So roughly 450 when you can actually turn it on.

“After 3 practice sessions the Ghost and 206 seem to be same engines. 50 laps at MCC and neither of us can gain more than 5 or 6 kart advantage. We both passed each other. Best lap times are almost identical. No issues with it so far.” -Scott Monison

Scott wrote that this am on our discord.

Wow lol. I thought architecturally they look nearly identical but I don’t think they come sealed do they?

No they’re not sealed. I think the biggest question mark is parity/tolerances between them, I haven’t seen anything regarding that yet. Although I have seen some tech people from AKRA trying to find out more about them

Mostly looks like they are being snapped up by mini bike enthusiasts so far.

No. Please, just, no…

I think this motor is more targeted at Dirt TBH.

Devils advocate… why not? 500 bucks seems like a friendly price point. The Unsealed part?

Because where does this compete? Does it undercut 206 and then we have fields full of cheaply built “Clone 2.0” motors? Or does it dilute the 206 program and split into its own class? Are parts interchangeable with 206 stuff? If not, is there a parts support network for these? And will builders and racers have to invest in a whole trailer full of new spare parts? And it isn’t sealed.

I agree James that parity would be the main concern. But I’ll echo what we say every time a new engine comes out, and note that the last thing karting needs is another class or engine package. 206 is probably the best thing to happen to entry-level karting in a long time. It’s been a great success. If it ain’t broke…

Reason #1: It’s a Predator

Do I need to go further?

Well yeah but if folks had to ask about making new engine types no one would ever make 'em. This doesn’t add anything new to the mix but it does add “cheep”.

Bunch of these on older race chassis and we have a league of “speedy karts”. I could totally see this as the engine for a league at a rental place or similar.

The Ghost could be a bit of a false economy compared to the 206 for competition. I’m not even sure if the package is targeted as such. Seems to have been kinda lobbed onto the market to see what happens.

Really there’s only about $200 difference by the time you’re on the track with the needed clutch, mount, chain guard etc.

For that extra $200 with the 206 you get a package that’s

Widely Adopted Parity is a known quantity. Stable rule set that’s been around for almost a decade. Well established tech tools and procedures. Sealed crankcase. Weekly racing series and other prize incentives. Proven resale value.

Racers tend to overlook these things and just look at engine specs, and I think that’s a mistake.

Then again… it’s hard to get 206’s now.

That’s not really a reason though. You could put any brand in there you like. Some would even put Briggs there.

For those looking to learn more, here’s some info and links:

22lb valve springs. 6200RPM rev limited coil. (Clone of) PZ20 Carb (22mm “Dekni”) Oil filler on top

Here’s a topic from Bob’s (It got a little sidetracked)

Blog article from Mark at EC Carburetors

https://www.eccarburetors.com/harbor-freight-ghost-212-help-karting

Ghost 212cc Facebook Group:

Dyno numbers from Gary Costanza. I think he’s going to do same with a 206 for comparison. 12.07@4800 , 13.79ft lb @ 4400 (The torque seems to fall off a cliff pretty fast though)

“Nice little motor . No issues out of the box . Idled down to 1300 and ran rich thru out the pull . Well tuned little carb. Out of the box the Ghost’s carb is tuned very good . As I dumped the throttle , the mix got richer . Thats what everybody whats their carb to do . When they go lean , then pickup , that gives you the dreaded “Bog” . I really can’t pickup much from this in fine tuning”

Head\Valve Details from Bryan Wesley

Charlie Zothner the intake port bowl area has a way less intrusive valve guide in it. The valve guide doesn’t protrude in to the bowl area of the intake port. As far as shape, nothing crazy different. As far as air flow, big difference.

On the topic of parity… here’s one concern which is the 6200RPM limit on the coil, but take what you will from a facebook comment without more information…

Blaise Poirier I’ve tested 2 the first one hit 5700 rpm and the second one hit 5950 rpm but didn’t make what yours pulled but every dyno is different there just a tuning tool

predator ghost engine shaft size

Here’s a break down of the internals.

I think the biggest thing we need is some data on parity/tolerances.

I haven’t seen much (read:anything) published yet, other than the remark about the rev limited coils above …

which if true kinda sinks the idea of it being an alternative to a 206 if there’s a peak RPM variance of up to 600RPM.

Anyone who was (or is still) around the clones will tell you an unsealed bottom end 4 cycle is not the road you want to go down. Your $550 engine will quickly become a $1500 engine. It becomes who has the part of the month or trick of the month. Look at any discussion on clones or predators (this is just a predator engine). They all started with the same intentions and devolved into something awful.

Maybe a good choice to replace a WF motor?

I know we are probably the only few tracks in US race WF. With its price, hp and reliability, this might be a good choice for somebody want little bit more HP.

I think I’d lean towards Tillotson for that use case since it has an established rule set with a spec clutch and parity is a known quantity.

We’re still in wild Wild West territory with the Ghost at this point.

:joy:

Once I finally got the kit in the engine and put it in my mini bike I thought I was going to die Lol

Good kit with some...

Posted by Michael Ballou on 10th Jun 2023

Kit was amazing when we got it good instructions online (got those from red beards garage on YouTube) the two major issues was finding a 1/4 inch torque wrench and a 6mm 12 point socket it was a nightmare but when installed worked amazing

Choose the right crankshaft bolt size for your Predator engine

Last Updated on August 17, 2023 by Pittalks

Are you working on installing a torque converter or centrifugal clutch onto your Predator engine? If so, you’ll need to make sure you have the correct size bolts for the job.

Keep reading to learn what size crankshaft and mounting bolts you need for your Predator engine.

Note: Predator engines are designed for the North America market, that’s why they all use SAE standard. Do NOT try to replace them with a similar metric bolt, it will strip the holes out.

Predator 212cc engines use a 5/16”-24 bolt for the crankshaft. 5/16” is the size of the bolt’s hex head, the number 24 is the number of threads per inch.

predator 212cc shaft diagram

Make sure you count the threads on the crankshaft bolt before you try to put it on. Any number other than 24 (fine thread) is not the correct bolt and could damage your engine.

Many people have made this mistake by using a 5/16”-20 bolt, which is a coarse thread.

You can easily buy this clutch bolt kit for Predator 212cc on Amazon, the kit also includes a washer.

Predator 301cc shaft bolt size

Unlike any other predator engine in this article, predator 301cc uses a 7/16″-20 bolt, which is a coarse threaded one.

predator 301cc shaft diagram

This type of bolt is pretty hard to find if you plan to buy it at your local store. But you can order it online very easily.

Predator 420cc shaft bolt size

The crankshaft bolt for a Predator 420cc engine is a 3/8″-24. This is also a fine threaded bolt. This clutch bolt is also used in Predator 346cc and 670cc.

predator ghost engine shaft size

You can order this kit online and it’ll have everything you need.

Other Predator engines

Small Predator 79cc use a 5/16″-24 shaft bolt, just like 212cc.

Bigger Predator engines (346, 420, 670) use 3/8″-24 bolts as they have similar crankshaft sizes.

Why it’s easy to thread at first, but it gets hard later?

As mentioned above, make sure you have the correct number of threads per inch. If you have already checked it, there are three possibilities:

  • You were having difficulty hand threading the bolt because it was clogged with gunk.
  • The bolt’s threads were knicked, in this case, get a new one.
  • Cross threading – this is very likely to happen if you are using an impact wrench or electric ratchet, use your hands instead.

Engine for North America market >>SAE standard (don’t try to find similar metric bolts). Predators don’t use metric bolts on the side cover or the crankshaft. If you try and use the metric bolts it will strip the holes out.

So we all heard from Harbor Freight that the Predator 212cc was going to be replaced by the Predator 224cc and we were speculating that all the Predator 212cc classes at our local kart tracks would utilize the 224cc Predator instead but now that Harbor Freight relased the Predator 212cc specifically for kart racing IDK the price, but it has a mukini carb on it so it looks nice.

The Ultimate Guide to the Predator 212cc Engine

Aug 29th 2023

Looking for a Predator 212 mini bike for sale? Go through this comprehensive review of the 212cc Predator engine, the upgrades possible, and the specifications before taking the plunge.

With a mini bike or a go-kart, you can either choose to putter around the backyard or take your mean machine onto dirt or surfaced race tracks, depending on the engine and the upgrades that you have opted for. However, this clear distinction has been blurred with the advent of the 212cc Predator 212cc Engine

It has really destroyed the competition because not only is it a high-performing and durable engine but the cost will not burn a hole in your pocket. Moreover, with Predator 212 upgrades, you can increase the performance manifold as per your requirements.

The Predator 212 engine is a performer right out of the box. Whether you are restoring your old go-kart or mini bike and breathing new life into it or adding an extra punch by upgrading your old engine to a 212cc one, it should be the 212cc Predator all the way because of its power and durability. And there is no better source to order one from than OMB Warehouse.

Further, for upgrades, you can get all the required parts, from Predator 212 engine upgrades to Predator 212 carb upgrades . Most importantly, all spares are sourced by us from the manufacturer and leading suppliers from around the globe and hence you get high-quality OEM-grade spares and parts.

Drop an email to us before you order. Our experts will ensure that you get the correct parts and need not go through the hassle of replacements.

The Predator 212 Engine

#specifications.

The Predator 212 is perhaps the most popular and top-of-the-line mini bike and go-kart racing engine that is available in the market with a great cost-to-performance ratio. This means that the power and performance that you get from the engine are at a relatively affordable cost due to its moderate price.

The 212 Predator is a gasoline engine with overhead valves for longer life, and cleaner gas-saving performance. Since the horizontal shaft is ball-bearing mounted, it is an ideal replacement for any standard engine configurations. Let us check out the other specifications of this engine in detail.

  • Durable cast iron cylinder that withstands wear and tear.
  • User-friendly controls, making for quick starting and easy operations
  • When the oil volume reaches levels that are not safe for operations, sensors in the engine shut it down automatically.
  • High durability due to upgraded engineering and construction
  • Fuel shut off for safe transport
  • Displacement of 212cc and output of 6.5HP, ideal to power any type of mini bike or go-kart.
  • Produces 8.1 ft-lb of torque at 2,500rpm
  • The engine is available with a recoil starter which can be switched to electric start via an aftermarket upgrade.
  • Is available in both Predator 212 Hemi and non-Hemi configurations.

# Suitability

The Predator 212cc, apart from go-karts and mini bikes is also a perfect propulsion medium for pressure washers, cement mixers, compressors, mowers, log splitters, vacuums, tillers, water pumps, chipper/shredders, generators, and blowers.

The high power of the Predator 212 engine has a direct effect on the top speed. Install in your go-kart and you have an assured top speed of between 25-35 mph. However, this range is only for reference and is applicable to standard go-karts and mini-bikes only. A lot depends on the type, size, and weight of the machine and the rider, and the aerodynamics of the vehicle.

Predator 212 Turbo Kit

One of the advantages of the Predator 212cc engine is that you can upgrade it and get optimized power and performance from it. However, to ensure that the Predator 212 engine upgrades carried out are of the highest order, it is necessary that you get the needed parts only from a dealer who can be trusted to deliver them. At OMB Warehouse, we offer OEM-quality Predator 212 upgrades that will boost engine performance many times over.

Check out the Predator 212 turbo kit in our stocks .

This kit is for a mini bike carburetor, mini bike Coleman, and a comprehensive set for Predator 212 upgrades. It includes a Predator 212 carburetor , air filter kit, and exhaust pipe muffler kit among other performance parts with each being made from high-quality materials for optimal performance and durability. Before ordering, please check your machine model and size as much as possible to ensure the best fit and avoid unwarranted replacement. In case of doubt, call our experts at OIMB Warehouse.

Installing this turbo kit is as easy as it can get. With a full set of accessories including an air filter kit with adapter, exhaust pipe muffler kit, and main jet kit, having it fitted to a Predator 212 is a breeze. Everything you need is included in one convenient package, making upgrading your engine quick and hassle-free.

This package includes everything you need for your performance upgrade, including a Predator 212 carburetor, air filter, exhaust pipe, muffler, spark plug, bolts, hex nuts, wrench, gaskets, emulsion tube, main jet, and adapter kit. All components are made from wear and corrosion-resistant materials, ensuring long-lasting performance.

Predator 212 Engine Upgrades

With a displacement of 212cc and an output of 6.5HP, the 212 Predator will typically meet the needs of any go-kart or mini-bike user. But you might still want to take performance to the next level. In that case, you should go for Predator 212 upgrades and Predator 212 engine upgrades for your mini bike or any other type of vehicle or equipment.

There are two very important factors to be taken into account when you consider any form of engine upgrade.

#Engine Stress

Any modification of your 212cc Predator engine on whatever vehicle or equipment it is installed on will definitely lead to component stress inside the engine as the parts are exposed to higher speeds and friction. Note that the stock valves will float at about the 5,500 rpm mark, preventing the engine from going above this level.

To go beyond this standard after an upgrade, the valve springs have to be replaced to either 18 lbs, 22 lbs, 26 lbs, or 36 lbs. You must also check for Predator 212 Hemi and non-Hemi compatibility before doing so.

#Removal of the Speed Governor

The second critical step to be followed before any Predator 212 upgrades is the removal of the speed governor. If you do not do so from your Predator 212 cc engine, there is no point in upgrading it as the speed and rpm will be limited to previous levels only. Removing the speed governor is not a very challenging task. By following the manual, using the right tools, and having enough space to work in, carrying out this work should not pose any problems for you.

Predator 212cc Engine Performance Parts

Performance parts are designed to increase various outputs of the engine that are a cut above what a stock engine has to offer. Here are a couple of them that you can install in your 212 Predator to boost the power and performance.

The regular air filter and intake prevent the engine from breathing in too much air. But the less restriction you have for the air intake of the engine, the more air and fuel will enter the combustion chamber. Install a 212 Predator high-flow intake adapter and high-flow air filter that will bolt onto the existing Predator 212 carburetor, requiring no more than a screwdriver and wrench to fit them. This modification will give extra power to the engine when you step on the gas.

The stock Predator 212cc engine has a muffler that prevents the engine from breathing out too much air. On the other hand, if you have a lot of air coming into the engine, it should be released with as little resistance as possible to increase performance. This is where the performance high-flow exhaust header for a Predator 212 comes in handy as a performance part.

Combining the two, by shoving air and fuel quickly into the engine and then releasing it with little resistance after combustion, you can add some serious horsepower and torque to the engine that will have the adrenal flowing when you throttle up.

A word of advice here. While installing these two performance parts, you are putting in more air into the engine and will need to drill the jet a bit bigger. This will allow more fuel to enter the combustion chamber as otherwise, with the governor removed, it will lead to a “lean” condition where the engine will overheat, resulting in a burnout.

Tillotson 212 vs. Predator 212 cc engine

The two most popular 4-stroke engines in the market are the  Tillotson 212 and the Predator 212 and there has been a long-standing battle between them. Though both the engines have a similar design, what about the performance?

The Tillotson 212 is about 50% more expensive than the 212cc Predator engine. There are several reasons for this. While the two are similar in design, specifications, and internal components, the output of the Tillotson 212 is about 40% higher than its counterpart with 10-20% more torque at 2500rpm. But the Predator has both a non-Hemi and the new introduction, the Hemi version while the Tillotson 212 is available only in the Hemi configuration.

However, both are great value for money and are among the best go-kart engines. Get in touch with us at OMB Warehouse for more information about the Tillotson 212 engine.

The 212 Predator is a powerful engine with multiple applications. You can further increase the power and performance with kits and parts that will take the output to the next level. Contact us at OMB Warehouse for more information about the Predator 212cc engine.

Best Clutch For Predator 212 Engines

A go-kart clutch is a mechanical device that engages power transmission from the engine to the rear axle. It’s attached to the crankshaft of the engine and is connected to the rear axle through a chain. 

In this review, I will be sharing with you the best centrifugal clutches for your Predator 212 engine. Below the reviews, you’ll find an extensive buying guide that will talk about what aspects you should consider, so that you can make an informed purchase decision. 

1. Teantech Go-Kart Clutch 

predator ghost engine shaft size

Clutch Features

  • Predator 212 Compatible
  • Chain Size: #40/41/420
  • Speed: 2300 ± 300 rpm

The Teantech Go-Kart Clutch is the best clutch for Predator 212 engines, as it’s made of high-quality parts and contains a compatible #40/41/420 chain. While it comes with various bore diameter options, it’s important that you select the 3/4” variant. 

This go-kart clutch features a 10-tooth sprocket and a height of 2.17” (55mm) and a diameter of 4.21” (107mm), making it a great clutch for a Predator 212 engine. It also has an engagement speed of 2,300 ± 300 rpm, which is fairly common.

Specification:

  • Bore Diameter: 3/4″
  • Sprocket Teeth: 10
  • Clutch Height: 55mm (2.17″)
  • Clutch Diameter: 107mm (4.21″)

Compatibility:

  • Predator 212: Compatible
  • Recommended HP: 2 – 6.5 hp

2. Tiot Go-Kart Clutch 

predator ghost engine shaft size

The Tiot Go-Kart Clutch is another great choice for Predator engines, as it features a 3/4″ bore diameter which is compatible with the engine’s 3/4″ shaft diameter. This clutch also comes with a compatible chain, which means that you won’t need to source for one separately. 

It’s 4.2” in diameter and 0.97” thick (without the sprocket). It also has an engagement range of 2,300 ± 300 rpm and a 10-tooth sprocket, making it an ideal choice for go-karts that are equipped with Predator 212 engines.

  • Clutch Diameter: 107mm (4.2″)

3. LotFancy Go-Kart Clutch 

predator ghost engine shaft size

Next in this list is the LotFancy Go-Kart Clutch. Similar to the other clutches mentioned in this list, it features a 10-tooth sprocket and a 3/4” bore diameter, making it a great choice for Predator 212 engines. Having a 10-tooth sprocket also means that it’s compatible with a #40, #41 or #420 chain. 

However, take note that this clutch doesn’t come with a chain included, meaning that you’ll need to purchase it separately. As far as dimensions are concerned, it has an height of 2.17” (55mm) and an overall diameter of 4.21” (107mm).

4. FDJ Go-Kart Clutch

The FDJ Go-Kart Clutch is another suitable pick for the Predator 212 engine. Having an engagement range of  2,300 ± 300 rpm (the same as the rest of the clutches on this list) and a recommended engine output of 2 – 6.5 hp, makes it a great pick.

Moreover, it also features a 3/4” bore diameter and a built-in keyway, making it convenient to install. It’s got an outside diameter of 4.75″, a clutch back to sprocket width of 2.5” and a total width of 3″, which is ideal. As this clutch is slightly larger than normal, it’s best to ensure that it fits.

  • Clutch Height: 63.5mm (2.5″)
  • Clutch Diameter: 121mm (4.75″)

5. Motovecor Go-Kart Clutch

The Motovecor Go-Kart Clutch is also compatible with the Predator 212 engine, as it features a 3/4” bore and fits any #40, #41 and #420 chain, since it has a 10-tooth sprocket. It’s also got a similar engagement range.

This clutch starts engaging around 2,000 rpm and is fully engaged between 2,300 to 2,600 rpm, which makes it compatible with any engine that has a maximum output of 6.5 hp. The Predator 212 engine has 6.5 hp stock, so it’s a good choice.

Buying Guide: Selecting the Best Clutch For Your Predator Engine

When looking for a clutch for your Predator 212 engine, it’s important that you consider various aspects such as the compatibility, bore diameter, chain size, sprocket teeth and engagement range. This section aims to provide you with as much relevant information as possible, to help you make an informed purchase decision. 

Compatibility

I’ve created a table with the three most common centrifugal clutches that are available on the market. The clutches that are compatible with a Predator 212 engine have different bore diameters and chain size compatibility. 

As you can see, the Predator 212cc engine has two compatible centrifugal clutch that can be used: the 10T & 3/4″ Clutch and the 12T & 3/4″ Clutch . However, I highly recommend the 10T & 3/4″ Clutch, as it’s compatible with larger and more heavy-duty chains. 

Let’s explore the bore diameter and recommended chain size in a little more detail. 

Bore Diameter

One of the most important things that you’ll need to take note of is the clutch bore diameter, as this has to be compatible with your Predator 212 engine. 

predator 212 bore shaft diameter

In the image above, you’ll see that the bore of the clutch needs to be 3/4″ in order for it to be compatible with the Predator 212 engine. This is because the shaft diameter (diameter of the engine’s crankshaft) is also 3/4″ and the go-kart clutch slides on top of the crankshaft.

This also means that clutches which have other bore diameter sizes such as 5/8″ are not compatible with your Predator engine. Therefore, it’s important to look at the bore diameter carefully before deciding which clutch to purchase.

When looking at the Predator 212 go-kart clutch, you’ll have the options of a 3/4″ bore with a 10-tooth sprocket or a 12-tooth sprocket. The important thing to understand here a 10-tooth sprocket clutch supports #40, #41 and #420 chain, whereas the 12-tooth sprocket clutch supports a #35 chain. 

predator engine clutch chain size

As you can see from the illustration above the pitch of a #35 chain is relatively small at 3/8″. I don’t recommend #35 chains, although it’s possible to use them on go-karts. However, chances are that they may break under a too heavy load. 

Instead, I would recommend that you opt for a clutch that is has 10 sprockets and supports a #40/41/420 chain. These chains have a 1/2″ pitch and are also larger in size. Therefore, you’ll be able to pick either a #40, #41 or #420 chain, which is more durable. 

If you need more information on the various aspects of chain sizes, feel free to check out the go-kart chain size chart that I created. 

Sprocket Teeth

As you’ll need to opt for a clutch with a 3/4″ bore diameter, you’ll have the choice of a 10-sprocket or 12-sprocket version. There are two main differences between both types of Predator clutches. 

The 10-sprocket clutch is compatible with a #40/41/420 chain, which I highly recommend, while the 12-sprocket clutch is only compatible with a #35 chain. 

Engagement Speed

You will also see that each clutch has a specific engagement range. The engagement range of a go-kart clutch the speed at which it engages. When the crankshaft of the Predator 212 engine reaches that speed (rpm), the friction material of the clutch makes contact with the outer drum. 

Once it makes contact, it engages and enables the clutch to spin with the crankshaft, in order to transfer the rotational power from the engine to the rear axle, and ultimately to the wheels. 

Most go-kart clutches that are compatible with Predator 212 engines have an engagement range of 2,300 ± 300 rpm, meaning somewhere between 2,000 and 2,600 rpm. 

Engine Output

The output engine of a go-kart determines its power and ultimately how fast your go-kart is. The Predator 212 engine has an output of 6.5 hp. Most commercially available centrifugal clutches are suitable for up to 8 hp, which make them suitable for the Predator 212 engine. 

If you have installed any type of Predator engine mods or upgraded any components that increase the overall output of your engine above 8 hp, then I recommend that you either opt for a heavy-duty clutch or a racing clutch. 

This is because an overpowered engine may cause excessive wear on a regular clutch causing it to fail over the long term. 

You’ll also notice that each clutch will usually have a recommended maximum tire size, which is about 15” or less. Larger tires aren’t compatible with these types of clutches and it’s best to ensure that your tire size doesn’t exceed this diameter limit. 

Frequently Asked Questions

If you’re looking for the best go-kart clutch for your Predator 212 engine and still have some questions, then you are at the right place. I’ve compiled a list of the most frequently asked questions on this topic. If you have any questions that aren’t on this list, feel free to get in touch and I’ll be happy to address them. 

What Type of Clutch is Best For a Predator 212 Engine

There are various types of go-kart clutches that work differently, but have the same purpose and function. 

  • Centrifugal Clutches
  • Hydraulic Clutches
  • Electromagnetic Clutches

The most commonly used clutch is a centrifugal clutch, which is also featured in the review section. I recommend centrifugal clutches over any other type, as they are a lot more affordable and require less maintenance than electromagnetic and hydraulic clutches. 

Is a Clutch or a Torque Converter Better For a Predator Engine?

It really depends on what type of go-kart you have. If you have a predator engine installed on your off-road go-kart and you do a lot of off-road racing, then a torque converter may be preferred. 

On the other hand, a go-kart clutch is more common on homemade or racing go-karts. Check out my guide on go-kart clutches vs torque converters for more information on this topic.

  6. Bolt for 212cc Predator engine shaft?

    5/16"-24 means the size of the bolt is 5/16" and the -24 means there are 24 threads per inch on the bolt so making it a fine thread bolt. On a normal 5/16" bolt there is 18 threads per inch making it a coarse thread. As far as the SAE/Metric thing goes- it's because the engine was optioned for the north american market.

  12. Choose the right crankshaft bolt size for your Predator engine

    Predator 212cc engines use a 5/16"-24 bolt for the crankshaft. 5/16" is the size of the bolt's hex head, the number 24 is the number of threads per inch. Make sure you count the threads on the crankshaft bolt before you try to put it on. Any number other than 24 (fine thread) is not the correct bolt and could damage your engine.
