Minibike builds and tips!!!

This summer, I threw together a couple minibikes and this is the following footage of the completed projects. My new job made it hard to upload several videos every week, so I decided to pile them all into one huge episode. Feel free to ask questions about the projects. Enjoy!

[@teddyy1213]

i watched this video near last christmas, since then, i have built my own mini bike by myself, and it's sweet! thanks for the inspiration

[@mikesuzio2566]

yeah i didn't wanna be building a minibike cause i would mess up a build i just got the stock 212cc mega moto 2 months ago 80 percent assembled in a crate and box after 1 oil change and with 93 octane fuel it goes 40ish mph all day

[@usnva5638]

@@jerryking1434 No, because he's a liar.

[@jeremibisher5611]

The red bike with suspension came with a 3.5 Tecumseh and had a tank mounted on the top of the frame.

[@alfredwall1996]

I put the predator on my Sears Roper without the torque converter drive. Just 40 chain and good clutch, remote tank, carb rejet and header. engine is lifted as you did. runs great!

[@stringtutorials3390]

I am glad I am not the only one struggling with an engine to fit !! Great vid

that's the bikes I like with the old school look like the ones when I was a kid. thumbs up good info

Keep it up! I love your videos because you wing stuff like me! And can't wait for the driving on the racing minibike!

[@gracieluv18]

For future reference you could clamp a thick piece of copper over the bolt holes so you don't weld over them. The copper won't hold the weld. Or you could pick up a nice 110 ting inverter and torch with gas hose for about 300 bucks

[@leonv9744]

you could have bolted a plate and extended it out forward to mount the engine

[@jefftrego2362]

Love the burnout! cool build.

[@gunz_n_bikes171]

You only need to hone the cylinder if theres scaring in the cylinder but i do recommend replacing everything else and modify the the intake port

[@hijper7053]

Cool projects, going to be starting a mini bike build myself within the next couple weeks

[@luckyfawker2646]

The so called tork converter is a must. Cheaper then replacement of burnt clutches.✌🐸

[@udizzy1969]

Cool Projects brother, Cheers The Dizz.

[@douglaswilson3978]

Awesome bike.❤❤

[@jeep2003]

Nice bikes the red one is built for an old tecumseh hs engine with the gas tank in front and small carb in the back. alot of bikes are like that it sucks but it is what it is. alot of guys put aftermarket or tecumseh carbs on the briggs engines to fit them better

[@bignickthegreat]

+jeep2003 Ahh right, Techumsehs! I havent worked with them very much, that's why that never popped into my head

[@ProjectRedfoot]

good set of bikes you got there

[@GeorgiaRidgerunner]

i like it thanks for the upload

[@justinmaxwell1608]

if you keep a half inch of stock pipe on your flange and weld pipe over it it will increase your torque via a bit of back pressure turbulence

[@ryanedmondson6892]

the red bike is sears roper. the trick is to use spacers behind the rear mount bolts. briggs only.

[@leoscustombuilds9717]

The red one is supposed to have a top mounted gas tank, like a motorcycle. But those are very nice mini bikes.

[@dalejackson5003]

take out the governor from the 212, make a step pipe exhaust i made mine from 2 different slide fittings for fencing, k&n style air filter, and 140 emoltion tube with jets and you'll be pumping out about 9 hp from that 212 and don't really worry about a bilit rod and flywheel i've run mine for 3 years with this set up with no problems

[@dalejackson5003]

great to see more videos!

[@weszef4815]

What's a step pipe exhaust and

[@weszef4815]

140 emoltion tube with jets?

[@dalejackson5003]

A step pipe is a like that progressively gets bigger in steps from 1 inch to 1.5 and so A 140 emotion tube is a get out of a Honda gx 140 that gives a gx 200 more tourge and jets are just bigger sizes that allow more gas into the carb

[@weszef4815]

+Dale Jackson do basically your saying that style header pipe and some bigger jets in the carb can give you 2-3 more hp?

[@braedonmills834]

Ok now I'm gonna start building on and I'm only 12. I have money saved up and my moms boyfriend can weld the parts together I hope I can get it done before Christmas so I can drive it😄

[@Tmansgokarts]

Nice set of minis, I dont know if it was camera shake but at 14:42 it looked like the belt on the TC wanted to fold over at high RPMs. not sure.

[@TheMatt70140]

Man those minibike need rescuing from you from all the cobbling!!!!!! Lol

[@frequenzzzs9750]

man nick!!! you should post more often your videos are top notch

[@ebuff57]

The Teceumseh engines were the norm for mini bikes (B&S wouldn't warranty anything on 2 wheels), like the old HS 4hp tecumsehs had the gas tank on the front, rather than on the rear, is probably what those frames were designed for.

[@bignickthegreat]

+ebuff57 Yes, totally true. Ive had little experience with tecs so didnt cross my mind. Thanks!

[@dr.minibikemr.gokart6602]

why wouldn't you just get a longer chain if the motor could go forward more? You have the ability to weld. You could have added a plate to the mounts for the clearance forward even more. making your own motor mounts was a good idea but could have been better planned. Dont cut the frame if you don have to. You know that because you had to fix it afterwards. Once you start adding power to the motors, you are going to weld more to enforce it.

[@patrikmuller151]

OMG you are baaack!!!!

[@tractorguysgarage7057]

I'm pretty sure they used 3 or 5hp Tecumseh engines on the red minibike. They had a carb on one side and tank on the other.

[@timelapsenewengland2317]

Tecumseh 3.5 hp is meant for that red mini bike.

[@doglegjake6788]

awesome work !!

[@codycheney3401]

hey i would love to know more about the achol that it runs on and what was done so it would run on the achol as well ..... maybe you could show us all !

[@randomrcprojects3754]

Your lack of proper performance mods bothers me when you put the straight pipe you need more air into the engine and to jet the carb so it doesn’t run lean

[@chuckhuff7123]

Man look at that monkey back brake setup. Just like in the 1960s when everything was much simpler.😅

[@tizgrowinghands]

There's a lot that you can get, with a motor mount plate for what you wanna do. I have a Baja Doodlbug with a Predator 212 motor. Try getting on a minibike forum on FB. There you can get all the technical support you need.

[@lyndelbeckwith1706]

CUT, WELD, REVISE, then put any engine you want in any frame.

[@3101010]

PRO TIP: next time buy a longer chain and move the engine ahead 4 inches.

[@wakeywakey4289]

Red/orange one is a Sears Roper without the gas tank...Id like to buy the blue one

[@speedbob712]

Your red one is a sears roper minibike. I have one i just picked up. the challenges lol. I'm setting mine up for the 212 hemi.

[@1Also]

Is it time for another mini bike build? Maybe a ski on the front and a dirt bike tire on the back. For winter ripping?

[@slimjim119]

cool last one you should have drove it

[@DonovanBryant92]

i know how you feel about the Briggs Flathead mine had the exact same issues had a badly damaged cylinder beaten up camshaft and worn out bearings

[@cashwhite9158]

u can put any of thoes motors all u have to do is take off the gas tank easy fix they have small gas tanks to fit anywere

[@adrianflores6116]

They might have had those engines but moved the tank or relocated it.

i own a 1975 HPE cat mini bike i bought it from a junkyard last year for 10 bucks it had no engine but when i saved up enough money i bought a 212 predator and it bolted right up didnt have to cut anything

[@MK2Scirocco]

How about camera angles where we can see you riding it... I feel a bit jipped not being able to see the blue one get ridden... How fast are they?

[@bignickthegreat]

Sorry, I’m still learning how to be a good youtuber, all of these bikes have been sold for a long time now. The red one was by far the best, it had the highest top speed probably 45 mph and was the most driveable

[@billykenyon542]

take the gas tank off the preadeddor and get a gas tank that goes on the frame in frount of the seat had the same problem you might half to take the egsaust off and get a smaller one and you might half to get a smaller air filter to or just take it off

[@hozkos6100]

rather than modify or notch the frame because of the gas tank, why not massage the tank in that spot and reshape the tank a bit so it fits? A ball peen hammer can work wonders so long that the tank doesn't have any seam or other structural feature in that spot.

[@wonderfulwino4265]

[@vetealaverga8531]

5.5 Honda or 4.0 Honda would fix perfect

[@gregorytimmons4777]

Why not take the tank off and mount it on the top frame rail? You are gonna have to get a lot more imaginative for this to work out for you. Yeah, just remount the gas tank.

[@SeeHowItGoes]

Gregory Timmons 100% would have been so much easier with the engine he wanted aswell

[@propabilityfpv303]

Why not move the gas tank instead of cutting the frame?

[@redmantv1710]

Dude thats awsome

[@ATrustInThrust]

Good to see you are back, just a bit of helpful criticism I thought I might share is that a video of driving from on the minibike isn't very fun to watch it's much nicer to watch flyby S or just set a camera on some books in the yard in multiple places and peice together a lap wit a bunch of different takes. You do s great job just thought it might be helpful. Also look at the way cars and cameras films their driving videos, usually it's about 75% watching someone on the bike/kart and 25% head or wheelcam

[@bignickthegreat]

+LemonPie4Me Hey man, the world needs more youtubers like you. Helpful and constructive. I appreciate that! I have no problem admitting that I cut corners filming the work on these bikes.

[@bodeine454]

I enjoyed the video! I have a go kart project going right now and a mini bike on the back burner to be built next. Question is I think that the first mini bike was probably designed to use a centrifugal clutch like mine only mine is more of an offroad mini bike with taller tires, shocks in the back and springs on the front end. The thing is when you mount a torque converter I believe that the final chain drive is over to the right side about an inch or so from where a clutch chain would be which means that I will probably need to move the engine to the left in order for the chain to line up with the rear wheel sprocket. Is that what you basically did along with raising it? I haven't mocked everything up on it yet but I think I'm gonna have to move the engine to the left an inch or so and I think that the engine is already over to the left as it is, not sure I really want to move it but I may not have any choice. It already looks out of balance weight wise from left to right because of how far left from middle the engine sits. Any advice?

[@DonovanBryant92]

i bought a Briggs Flathead from my local junkyard sadly it was in really bad shape the piston will never be able to run in a engine again it had scrapes all over the piston but the engine block is able to be reused

[@bradfordhays7855]

Zip tie on the plug wire, wish I'd thought of that when I was a kid. when the throttle cable broke wide open on my go-cart ( with no brakes ) and I had to reach back, and pull it off, by hand , twice , because I let go the first time and the wire it hit the spark plug again and started running again ...cool trick
