Lil Rascal Mini Bike 79cc Predator Engine Swap

In todays video we engine swap our DIY Mini Bike, The Little Rascal. We do a top speed on the Tillotson 212 then pull that engine and clutch to put on a 79cc with a cvt. We didn't really know what to expect with the 79cc because we've never messed with one before. It surprised all of us by how well it worked and the top speed of 18mph. We down graded the bike with this engine so my son, Grayson, can have it to ride.

[@timelson6659]

Yes I want to see a performance 79cc!

[@Stingyduce]

They have some Place called Agk.com

[@mrpartridge8765]

Do a full performance build on that little guy. port and polish shave the head a bit and throw some billet parts at it. I haven't seen anyone build up one of those and Ive been wanting to see what they are capable of. if anyone can do it you guys can.

[@collinklitz7434]

High RPM too!

[@youngchap4941]

i took the governor out of mine and the top speed i have hit was 35mph it does have some compression loss though I think I should be hitting 40mph I only weigh 120 its plenty fast for me for right now atleast good lil motor

[@darrenroot4562]

agk makes parts for it. their mild build make 7hp and 6000rpm

[@noahpaulette1490]

Yeah I've been wanting to see someone do a performance build on one of the 79cc engines but I haven't been able to find anything.

[@darrenroot4562]

@@noahpaulette1490 my buddy's minibike has a bone stock 79cc with 1 tooth retarded cam timing and a long gear. with a giant ass seat and a friggin cooler strapped to the front of it it goes 40mph

[@williambroome5204]

Yes! Please build a 79. You can always swap it on a slow day, I’m kind of curious after watching this one!

[@bryduhbikeguy]

"Harryyyyy..."Had tears from laughter."My hands are freezing.""Here,take these extra gloves.My hands were getting sweaty anyway"...Was what came to mind,when I see you 2,and a little bike.

[@mje19D]

The Dumb and Dumber reference was funny.

[@mconfluence]

You need to put a v-twin on one of those little rascal mini bikes! That would be a crazy fun mini bike

[@traedrose7963]

Love this set-up. Thanks for showing what the 79cc can do.

[@christopherfolker4976]

I honestly LOVE those little 79cc engines. I am doing a powerwheels build with one and it is just amazing. Good performance for a super small package. 1000000% do a full build on one!

[@maverickkartracing]

pretty cool build. makes me want to put one together for my grandson & great nephew.

[@stephensuverison6803]

Love the vids. Definitely would be cool to see the comparison between a stock 79cc vs a built one. Keep it up, you guys rock!🤘😎

[@samsgarage1716]

Not bad for a 79cc.Great job guys.👍

[@rong4189]

“....AND TOTALLY REDEEM YOURSELF!!!”

[@cozy_Fozy]

Absolutely want to see you build up a 79cc predator! ARC Racing finally just released a billet flywheel for the 79, this along with new valve springs, carb, & maybe a cam. Should do nicely 👌 Keep up the great work guys!

[@SilverShadow2LWB]

Great video. I think the 79cc is a perfect engine for many projects. A performance build without sacrificing too much reliability would be ideal. I've been waiting a year to watch you do one. Still waiting patiently. Thanks.

[@petergrubb3037]

More minibike stuff plz? That is why I subscribed. Thanks!

[@jerryguajardo1193]

I would definitely love to see more 79cc performance parts! My daughter's bike me something cool LOL

[@GoPowerSports]

Love the video! Great job fellas!

[@erwin5911]

Amazing! You swapped that motor like a pro! And the completed project is stupendous. I ask myself, how do you guys do it??? Has one of the big bike manufactures contacted you yet? Surly they have to be blown away!!!

[@cocreatorradio]

Thanks for doing this project. I have been thinking about putting a 79 cc on my fat tire bike and was wondering if it would work with an available torque converter. Now I know it will, so I will go ahead and get the parts. I'll make a video of the build.

[@RJ67.]

That lil mini bike brings back soooo many memories of my day & I back in the 1970's

[@navalinfidel3003]

Awesome channel! Cannot get enough of the toys lol.

[@SportbikerNZ]

Not too shabby for such a big step down in displacement.

[@bumblur]

I am interested in swapping out the 212 for the 79 for my grandson on my L'il Rascal. But, it looks like it requires a fab shop to do it, which I do not have. Thanks for sharing!

[@abrahampeshko1858]

Thank you for the video RBG and god bless

[@wandalawhern1033]

Love the videos!

[@mikebillman7234]

I'm doing this to my monster moto. Thank you for the step by step

[@peterchristlieb]

Mr Red Beard, out here in kommie do gooder land (Los Angeles) the 79cc has disappeared. It’s no longer CA compliant. Funny thing is, the new water pumps on display have a shiney red tank and fan covering a 98cc motor that’s also displayed on the new 1800W generators. The medium pumps have a red tank and fan shroud hiding a 212 Hemi! With the two Max performance motors out and the “Ghost” about to appear, I’m praying the 98cc will be the replacement. Can’t use the generator motor since they usually sport a tapered drive end on the crank with the side cover being the cast mount for the armature. The pumps look to bolt on to the normal cover and should have a straight keyed shaft (hopefully). Trying to put together an Azusa kit bike for small folks and really want a little motor like this. I’d pay good money for a 3 horse flathead if I could find one.

[@CumminsDsl93]

Hell yea. I wanna see how far a 79cc can go. That would be awsome!

[@Lahemi347]

Cant wait to see a trail ride

[@rncboy2]

Yes curious as to what one of these little guys will do.

[@masonr3706]

I love your videos!!!🥇🥇

[@rallyit11]

I just bought a 79cc to swap into my sons artic cat kitty cat. I’m glad I found this video and I want definitely to see a performance 79cc

[@danielroach8330]

Sick swap. Definitely build up a 79cc

[@delandbrooks3291]

"Jeepers Mister , You're really strong!!" RB "I know kid but smell ain't everything!"

[@jasonh3220]

so cute ... nice mini bike too :)

[@specialedjoe]

i have a baja viper with a 79cc predtor no other engine would fit i had to degoverned it to attach a linkage works great went up to 37 mph with 93 octane and 18 lb springs

[@rustybeatty6567]

Try using a 17 tooth front sprocket on the CVT transmission jut to what you get out of it first before doing any further performance mods to the engine.

[@dragonrider9244]

Heck yes See the 79 built.

[@alexturner2693]

Definitely would love to see a 79cc performance build

[@kevineasterday2332]

I'm shocked you didn't remove the governor. ALSO, on the Dodlebug mini bike you do not need the bottom mounting plate the 79cc comes with. Bolts in without it and sprockets line up properly to use a clutch instead of torque converter.

[@maxtaylor1026]

Got a Lil Rascal for my son. The only thing I dont like is the size of the rear sprocket. Can't hardly turn left without the sprocket/chain hittin the ground.

[@slimyelbow]

Interesting change sort of.

[@dylanpincombe2990]

Finally I’ve been waiting for you to mess with a 79cc predator. I figured you’d never do it since it doesn’t have a lot of power! But you should totally convince go Power sports to build parts for this!

[@dogprowilhelm7630]

Great upgrade for a Lil Rascal. What's the dyno H.P., upgrades in such a small package 79cc Predator engine and another Road to HP series? Small displacement engines RPM well, hint, hint...

[@reaper666grimm]

Nice to see how 79cc do. I've been thinking of using one for my kids. Question: Where on Earth can you stand downside-up(right side up) and upside-down?

[@johnclayton3015]

Wish i was a kid again with so much cool moni bikes an go carts

[@corybrown4028]

Build it up guys

[@emersonb5764]

So how’s the rake and trail geometry on that bike? From the looks of it the steering tube is too steep to get proper trail distance to avoid a squirrelly dangerous steering situation. Got an old Montgomery wards bike that’s like that and it’s super sketchy. Like trying to keep a shopping carts front caster wheel pointing out forward as you push the cart forward when it wants to flop around to lag behind instead.

[@beastgreen3054]

Yeah we all want to see the 79cc

[@seansysig]

Mrs. RBG makes a secret appearance. No more behind the camera a star is born.

[@johnnymerritt5969]

You're the man brother HA

[@ProbeGT2]

if you could put a smaller sprocket on the cvt, and remove the governor, upgrade valve spring and let it rev 5-6000 rpm, it would pull really well down low and have a higher top speed.

[@njmxjunkie3128]

What are my options performance wise with a 9hp briggs vangard

[@rodswim492]

Greg you guys need to get some clown wigs and nose for when you put you big butts on those little minis! Hilarious, you guys are great.

[@joshgoltare9742]

How would you hook up the throttle if you didn’t have the adapter thing

[@332ARA]

Can you tell me the overall width from pull cover to CVT cover? Thanks

[@rigourmortis]

Yip performance 79 🤙

[@sergeantcraphead]

Jeepers Mr! You're weely stwong!

[@jojojeep1]

How do you think it would work on a 12 inch mini bike tire with a 4to 1 gear ratio

[@ThePhoenix5211]

Any updates in that 79cc exhaust? I didn't see it in the GPS website anywhere. Please help

[@stevefavero3204]

Hey just out of curiosity are you guys gonna try a Wildcat 223cc? I just put one in my mototec 105 and it's a torquey little shit lol I'm 140 lbs and with me sitting as far forward as I can still picks up the front wheel effortlessly. Just a stage 1 with a swapped coil to get rid of the 4k limiter

[@SuperVettefan]

Mini buggy time, I need one really bad .

[@frank.R.productions106]

What’s the height of that motor the way you have it without the tank and stock intake and exhaust set up?

[@davidaldridge6585]

It would be really cool to see a predator 212 hemi with a stage 2 kit With! Electric start!

[@kevinjohnson9372]

Would u pkease play with some of those cheep little diesel motors they there said to be 3horse and 9 torques

[@R_Kyllonen]

Yes please build up the 79cc 😃

[@lindad.8412]

You got a link to the phone holder you got mounted on the handle bars?

[@oriohana5159]

what is the air filter lookin thing at the back of the seat?

[@Jt-ut6po]

Geepers mister braxton got grown!!!

[@MrThegabbster]

RB what sprockets did you run on the Drag bike and what was your E/T in the 1/8 th mile was it 13T@ 70 T I’m building a cx340 doodle bug dragster

[@DanielSmith-sk9ot]

You are awesome

[@jamesferrell9404]

Curious how yall got the 79cc predator to even pull. I put one on a mini bike cause no room whatsoever for a 212. But it refuses to pull up a hill and barely pulls on level ground. It has a 43 tooth rear if I counted it right with a 4.00x5 back wheel. If you could help guide me it would be appreciated. It had a 50cc 2 stroke to begin with that pulled me but it was slow going up hill. So figured the 79cc would be no issue. But was wrong

[@gmodprodukcs6404]

I'm building a go kart it's a grape escape from monco I'm wanting to put a new rear axle kit and I was wondering if you could recommend any kits that would work

[@rickjames4630]

Well heck yeah we wanna see that pimped out 79cc swap. Whatchu mean!?!! HAHA

[@dsnester2754]

I know this doesn't have anything to do with the video but good tires you got on that truck highly recommend them to anyone

[@koreywilliams4570]

I put a predator 212 in my home made mini bike. Its scarry as hell to ride since I've already taken a couple falls at 35 mph with no protection... brused up my heel pretty good that last time and couldn't walk for a couple days. To be fair I didn't have the brakes setup yet so I was doing the Flintstones. But since I've got them working now I feel the torque converter i have topping out at 5k rpm and it has a rattle to it that's super annoying. Thing was only like 60 bucks on Amazon so I definitely need to upgrade.

[@clubby1234]

Anybody have a link for that 79cc adapter plate?

[@leemer1]

Your lathe in the background at the end of the video appears to be a South Bend. What size is it?

[@WyFoster]

ARC now has a billet flywheel for the 79cc. The more you know!

[@cristianportillo9834]

Ive got a predator 212 stock with a 36t sprocket and Ive gotten it to 53 with it but 51 is more consistent of a top speed

[@jeremyTallen1]

Is there an aftermarket carb like the bigger 212s so you can do away with all the horrendous throttle linkage. So the throttle cable can just hook directly into the carb like the aftermarket carb you can buy for the bigger coleman bikes. I hope all that makes sense 😆

[@CRAZEDX100]

Agk sells a 19mm slide carb and intake manifold for these

[@jerrymoore1967]

Y'all should build a RCF micro drag bike. They are poppin right now in the mini bike world. Maybe with a 3" Jr. Dragster engine. Torque converter and all.

[@_o.0_.]

For sureeee!!!! 😂💯💯

[@adamwhite2120]

Mod it up. I got a 99cc on my ct100. It will do 38mph bored the carb ,air filter no gov, and a pipe. It is a fun ride

[@FangOfTruth]

How would a two stroke exhaust affect a four stroke engine? Especially something small like that 79 cc.

[@aarongrabowski3775]

Pretty sure you me effect. Unless you know more than i do. Gonna go out on a limb and say thats not the case though. Nope, im not cocky. Just smarter than your average bear boo boo.

[@schleyharvin6923]

Mine has a 79cc with regular clutch and does just fine actually and is quiet.

[@notimegarage8632]

I have a 79cc ill send out to you guys, its like new only used it for a day then went back an got a 212

[@nicdip8316]

What sprocket did you use?

[@mikesbarn1858]

I have a Coleman ct100u for my grandchildren and I plan to modify it once they are competent.

[@nickheisley5336]

You can make your own linkage out of a sheet of metal that cancels out the governor, mine goes 32mph+ with my linkage

[@332ARA]

So F79cc use standard threads and not metric?

[@mindyweeks7863]

Working on mine now top speed is around 22 so yea I will be upgrading my motor

[@motoman22atgmail]

You opened a can now. By November it’ll have a custom cam and some kind of forced induction... the people will demand it lol

[@aaronsukotsky3875]

Hahaha you did it perfect dumb and dumber impression hahahah😂

[@justinmoore7529]

I would love to see a 79cc performance build

[@brianmccann666]

My Second Suggestion.... Electric Minibike the Mini Rascal. 72v Batteries. 5000w motor. You guys could do it. You know you could. You'd have a blast on it too.

[@houset1794]

Cracks me up my Losi 5T 2.0 has an ALX 80 on it 😂

[@arnielinback1666]

Have you ever heard the 208 Briggs & Stratton

[@arthurbrice632]

yea i want to see it

[@Kirkorr123]

Love the Dumb and Dumber reference.
