Predator 212cc engine swap mini bike motorcycle part 2

I show how to DIY motor swap a Harbor Freight Predator 212cc engine into a mini bike, dirt bike, motorcycle. This bike is surprisingly fast with the 6.5hp/ 7HP hemi engine and CVT TAV 30 series torque converter transmission in it! This motor swap is a common upgrade for go karts but is easy to install on a motorcycle too. I have even seen this swapped into trucks and cars. This is a simple project that can easily be done over a weekend with a welder and angle grinder. There’s also a xr100 with a BBR big bore kit motor swapped cr80 in this video. In part 2 I pull the governor out of the engine and I installed a stage 1 kit into the predator motor, and even do a little spring adjustment to the CVT.
Here's some Amazon associate paid links if your looking for some of these parts. CVT torque converter amzn.to/2IySo3V
CVT torque converter amzn.to/2Wzmz4I
Both of these Torque converters fit 3/4" engine output shafts (predator 212cc engines have 3/4" shafts) and both kits come with the 40 pitch sprocket (this was the same size sprocket i modified to fit my chain pitch. I hope this helps you guys out.

Here's the Tachometer amzn.to/2WWqmZZ
Here's the curved tube I used for the intake runner amzn.to/2IWveV9

I agree with other people just imagine all the old bikes with a blown motor that can be resurrected with a $100.00 HF predator motor! I just purchased one of those belt drive CV units for around $50.00 on amazon! For $200.00 and a day of fabrication and welding your out riding! Awsome video

[@TheLordstrife]

Best budget mods you can add IMO. Black Mamba Jr. cam from smallenginecams, a gx160 head for higher compression ( I buy cheap ebay knockoffs), timing key, 91 octane for higher compression. I do recommend getting a billet rod, billet flywheel, valve retainers, valves that fit the new retainers, and 26lbs springs. most of that stuff you can get from ARC racing.

[@Mikefestiva]

Thanks for the suggestion! I ordered a stage 2 kit, in the next video I should have it modified and ripping :) Take care

I built a predator 212cc and use a billet aluminum flywheel. I have seen what stock flywheels do when used with no governor. Besides the billet is less than have the weight too. Don't forget also to install a billet aluminum connecting arm. These are designed to use with a performance builds with no govenor as they are stronger. Just a little food for thought. Great video, you smoked him easy. Too cool! Can't wait to see more.

[@stevelindsay3643]

It's great to see someone actually making a bike work well with these small 4 stroke engines. We've built a number of Karts and mini bikes using clones and have not yet used a Predator engine but they do seem to be a step up. With off the shelf parts, they are an easy engine to modify as are the clones from the vast amount of companies who put their name on them. I think I will get a 212 predator and give it a try in a moped, scooter type bike we bought online that does not seem to have any history or background to find anything about it anywhere. It is an odd shape with unique features. We were told it was made in China in the 1980s or 90s but that's all we know.

[@Mikefestiva]

Yes this little bike has been a lot of fun! The predator 6.5hp seems to be a good motor, I have one on my home built log splitter and it always starts first or second pull! There’s a lot of hip up parts available for these engines as well, for the $100 on sale I would definitely recommend trying one out 🙂

I have been out of the small trail bike business for 45years.and since I regretfully sold my 69 Penton. It was one of the early Pentons........I was hankering to get a new toy and bought an old Kaw 100KE but it has a trashed bottem end. I am getting ready to do a similar swap after seeing your first video. I am hopeing that I will not need to cut the frame to get the motor and cvt in. I am also worried about the foot peg issue. The swap actually looks to be a neat swap other than the bulky CVT. Too bad just a simple clutch is not a good option to eliminate much of the bulk. This whole Idea of these preditor swaps hopefully will revive many of the old trail bikes that have been abused and not maintained. Great videos....Keep up the good work.

It is nice to here some calm, smooth music while watching you work. Much better than cranking the heavy metal (which has its time and place.)

I found the replacement belt has lasted a lot longer then the original one that came with the CVT, I’m still running the replacement belt, I do plan to install a lager rear sprocket, this will help the belt last longer because it will fully engage at a slower speed, it’s the slipping on and off throttle at slow speeds that I think takes its toll on them.

[@kaseyrose4845]

Yes the flywheel WILL EXPLODE if you rev too high. If you don’t want to spend lots on a better flywheel go power sports sells pvl flywheels. Also consider just cutting off every other fin on your stock flywheel for less drag, it worked fine for me. Arc billet rod and mod2 cam will make this thing fly!!

[@JG-iw8mh]

The stock flywheels are cast. All cast iron flywheels are known for exploding over a certain rpm because the porous metal starts to lose its shape, flex, and crack. That being said ive only ever seen internet dudes explode them ive never personally had it hapen. I suggest getting the ARC billet flywheel with 32* timing built in. Run it on 93 octane it should like any cam you throw at it. I am in Indiana so our tuning greatly differs. Nice channel by the way, you have a subscriber. By the way if you lap the billet flywheel to the crank your using you can use it for years on any 212cc so not a bad investment.

Excellent video! Looking forward to the next and hopefully many more afterwards.

With stage one, I would guess the new speed will be 57-59 since the governor was removed.

I'm thinking if you had a variable gear that changes the ratio it would be a real big top speed but that's just my thinking direction. Great Job again!

you should get a billet flywheel for sure. i used to race these engines in box stock classes with my kart. so many stock flywheels were flying apart that it became the only/required mod you had to do in order to pass safety inspection. dont cheap out...its not worth letting that grenade go off next to you or someone else.

And there are five horse Briggs & Stratton engine and Junior Dragsters at the US Nationals Indianapolis Indiana that turned a hundred miles an hour in the quarter mile but they have a few modifications so they won't reach out and kill you and that has to do with starting with a Billet block start with then a fully counterweight Billet crankshaft custom roller bearing with a forged rod and forged piston valves titanium valve spring titanium pushrods titanium everything else cost of somewhere between 3500 and $5,000 and you got five horse Briggs that makes about 40 horsepower and a hundred miles an hour in a junior dragster but I'll bet for a whole lot cheap and build a all Circle flywheel with a crank like a Harley-Davidson Crank that would fit inside your motor and cut or buy a Billet rod with a more modern motorcycle piston and the tools to do it all for l e s s that of Junior dragster engine

I'd reccomend the stage 4 kit from GoPowerSports.com, but if you're short on change get the billet rod. Predator engines have a little scooper on the stock rods that splash oil around, and they have a tendency to break off and go through the block at high RPMs.

[@colinoakley8024]

They're referring to the actual metal flywheel. The metal fatigues, develops micro fractures, and eventually let's loose. And when it does, your engine is toast. I did a 212 on a 1980 rs175, same way you did. But my engine is a stage 2 with billet rod and flywheel. Well worth the money!

[@thatguy9890]

@UnEqual Reality The one on the carb? Most engines that are designed for generators or pumps etc have a Governing screw near the carb so that it doesn't over rev but I didn't see one on this engine And it Gets Up to the rev limit so I think it's the internal rev limiter not a fuel restriction Is there another screw? I'll have to take a look again when I have it out of storage

I saw the video. It's a 1980s dodge d50

You'd be better off staying with the 35 chain because there are more sprocket options. If you get a quality 35 chain it could easily handle 212 power. Others have done it. If you really want a bigger chain go with a 420. They work better with the CVT than the 40. The fat 40 chain will increase the possibility of chain strikes to the driven pulley and make alignment less forgiving.

[@thatguy9890]

@@Deucealive75 That Makes sense. The size #35 I have uaed stretches pretty bad Though! I think with a CVT the #35 would do better because It will shorten the axis from the Crankshaft output and the Rear sprocket and I think that the chain being streatched out that far end to end And having that Center leverage on it might play a decent part in the chain stretching so much. But I'm not sure, it just seems like it would.

[@Deucealive75]

@@thatguy9890 Agree on the shorter chain.

[@otm646]

If you are burning up the belt it's because you're asking too much and you are over geared. If you put a larger rear sprocket on the whole bike's going to behave better and never burn up a belt.

I had no idea that something like this was possible! I love it!

[@Mikefestiva]

Right on! It’s definitely a fun little machine, I have a stage 2 kit that I need to install soon, it should really wake up this engine 😀

@@Mikefestiva heck yeah man you have to do a video on it now lol! I have a doodle bug and just got one of these predator motors. Went on KZbin and found you! Now I say screw the doodle bug I'm building a dirt bike.

I love your channel that thing runs mint. I made one out off an old harley z90 I put a 8hp brigs and stratin . it ran good and we have Had it going 50+. So it ran good we blue the the motor. And we're not quitting we are raising the the back bone and we are putting a old 10hp.briggs that came out of A rototiller it runs pissa Dude.

If the Predator engine has a factory cast flywheel then it can fly apart self-destructing at high RPM.

[@danthemowermedic4444]

Have you had it happen to you?

[@enginesandoutdoors3238]

Daniel Morris predators are junk engines made cheap, that’s why so many people have them. I wouldn’t be surprised if it happened to someone.

[@danthemowermedic4444]

Yeah but he said to comment if it's happened to you. I in fact build these "junk" engines and I've been using the factory flywheel on my own personal one for about 7 years without it "exploding" lol all you have to do is make sure the magnets are re epoxied to the flywheel. The glue they use isn't the best and let's the magnets go that kills the flywheel. So speaking from years of experience their not junk. You just have to know exactly what your doing 😉

[@rayditzenberger9517]

Thanks for that info. I am just starting a swap into an old KE100 and willl probably do some simple mods ..... JB weld shold do the job nicely

[@danthemowermedic4444]

@@rayditzenberger9517 not a problem man, that's why I do that I do. I actually just had the chance to work on and upgrade a Tillitson 212 hemi. It's in a little Doodlebug frame with a 30 series comet torque converter and man it's the loudest torque monster I've ever worked on lol.

[@larryalexander4833]

Check out red beards garage channel . He can give you full details on the flywheel. The issue is cast iron flywheels aren't rated for the rpms. I use to build Briggs engines and I have saw a one of thier engines flywheels blow up .Luckly the guy didn't get hurt very much but parts went through a shop wall. Im liking build by the way cool bike

[@jrshaunwhite]

Dang great content man. Saw part 1 and 2 so far. My guess is 57mph after removing the governer. And man cant wait to see the reat of your videos, love the channel

[@Mikefestiva]

Thanks for checking out my bike videos! It’s a fun little machine 👍

[@wishbone20t]

Great video awesome build, now you need the billet rod, flywheel and Mikuni carb and that would really rip! I am looking for a bike, clearing some space in the garage. Screw messing with mini bike

Magnet comes off the stock flywheel knocks off the coil and bust the block trust me

Awesome d.i.y. video.. This is the kinda stuff im into.. Has that "Monster Garage" feel to it.. 🍻🍻🍻

[@danoiddano6891]

I’m guessing about 56 mph? It’s fast enough to have fun and hurt ya. What more could a grown man ask? Great vid tanks mang.
