Minibike builds and tips!!!

[@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.

[@ralphbenites1819]

Wow 🤩 how cool.you scored. Not many kids build mini bikes thease days.its great to see them come back 👍

[@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

[@BigAlWillis]

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

[@hijper7053]

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

[@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

[@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

[@thevictimcard7065]

been checking your channel for almost a year, can't believe you're finally back

[@arcturusbbqsausagemaking2435]

Great job Nice build She moves along pretty good Love the zip tie shut off system I use string lol !!

[@dungshute1836]

yes you're back! I missed watching your videos!!

[@bignickthegreat]

+Kaden Richardson Its been way too long! My new job has me tied down haha

[@dungshute1836]

I sure hope you can upload more often. Your videos are great!

[@chuckxdcools8562]

+bignickthegreat will u sell a mini bike frame

[@JustAGame-mk5yt]

im looking for set of tires

[@robertanandreabowman4947]

charles randall

[@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

[@Mdmblk09615]

Great job! I have a question, do you know where i can get a clutch or torque converter for a 301cc predator? Thank you and again great work!

[@leonv9744]

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

[@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 !

[@jefftrego2362]

Love the burnout! cool build.

[@luckyfawker2646]

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

[@gangstaprankesta4120]

Did you build the fames and if not where can I get material for making a frame

[@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?

[@guitaristinseattle]

I have the Predator engine and Mikuni 22 carb. Problem is, I can't connect one fuel line because the tanks connection is say much larger than the one the Mikuni. Can you recommend some type of adapter? Your thoughts?

[@ubiquidic9823]

guitaristinseattle put a hose clamp around it and tighten it up so it clamps on the hose

[@duncan9168]

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

[@arcturusbbqsausagemaking2435]

Great vid !! can you please tell me where the best place to buy mini bike motor parts and accessories clutches /sprockets jack shaft /throttles ect .

[@aldricracette4813]

Go power sports

[@bignickthegreat]

I usually stuck to ebay, every once in a while I’ll buy from go power sports or BMI karts

[@masonbabcock4961]

What size tires and how many teeth on the rear sprocket?

[@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.

[@bradfordhays7855]

Where do you get your frames from I can’t find any on Craig’s list or eBay

[@bignickthegreat]

Keep those eyes open! Deals are out there. Plus I think Facebook marketplace is where everyone is trying to sell right now so try that

[@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

[@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.

[@FIK3TriKs]

How fast does it go, like top speed on a road

[@petreeuk4439]

Where can you buy just the frames from?

[@DonovanBryant92]

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

[@camcoffey44]

Hey whats that pedal on the red bike for?

[@irishbear2663]

What is that red mb I have the same one but no tags or any type of way to identify it I wanna build it with my nephew any tips would be appreciated

[@bignickthegreat]

Irish Bear sorry I’m not real sure what kind of bike it was either. Was a quality frame though!

[@BdstarsiTFM]

I want to build an electric mini bike with pedals, any tips and tricks?

[@theghostly7]

anyone know what brand the blue frame is? looks familiar, specially around the engine mount area.

[@chrissargeant2254]

[@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?

[@brandongarcia9852]

i want to build my own mini bike but i don’t know where to get the parts. any suggestions l?

[@ryanedmondson6892]

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

[@ubiquidic9823]

Any idea on what type of frame the blue one is? or is it homemade

[@ubiquidic9823]

Thanks

[@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

[@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

[@carterlyons4026]

Hey I have the same engine and a mini bike frame but my freinds said that if you straight pipe it it decreases in power and ruins the valves because there is no back pressure please respond thank you

[@bignickthegreat]

CTL straight pipe exhausts are fine provided they are actually long enough. I try to make mine at least 18 inches long. If you make them any shorter than 12 inches that the problems your friends mentioned will likely start to show up. Tell your friends that they don’t know everything hahaha

[@carterlyons4026]

bignickthegreat thank you so much I have a frame exactly like your blue one

[@douglaswilson3978]

Awesome bike.❤❤

[@mazdagamming3559]

where I can buy mini bike wheels complete with his drum?

[@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!

[@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?

[@joewilliams783]

are you still going to use the same stuff that were in your project reveille vid in future projects

[@bignickthegreat]

+Joe Williams Yes, saving cash to buy better tools hahah

[@joewilliams783]

Thanks

[@et_builds5004]

What kind of welder do you have ?

[@ELMELOCOTONMARTIN]

what diameter of tires do you have there?

[@adraionmoney9422]

What kind of frame is this ???

[@brandonchavez3130]

what type of frame is the red one ?

[@nickcopek7804]

Sorry I'm new to this stuff, does an engine come with a gas tank?

[@charlieslattery5443]

Yes

[@evanradke3605]

You shouldn't have to apologize to ask a question man!

[@hectorinnes7427]

yes

[@leoscustombuilds9717]

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

[@propabilityfpv303]

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

[@andrewcharles5796]

where did u got those frames from

[@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

[@Mufassa]

What was the name of the second mini bike chassis?

[@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.

[@ryanedmondson6892]

i had one with a two speed stock transmission

[@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

[@doglegjake6788]

awesome work !!

[@aschbyg2718]

I want to build a mini bike but can u give me a list of all the parts I need? I'm new to this stuff.......

[@kaydeegee9859]

Aschby G look up mini bike kits bro

[@mikirodriguez209]

what does a torque converter do

[@brianmccann666]

In modern usage, a torque converter is generally a type of fluid coupling (but also being able to multiply torque) that is used to transfer rotating power from a prime mover, such as an internal combustion engine orelectric motor, to a rotating driven load. The torque converter normally takes the place of a mechanical clutch in a vehicle with an automatic transmission, allowing the load to be separated from the power source. It is usually located between the engine's flexplateand the transmission. The key characteristic of a torque converter is its ability to multiply torque when there is a substantial difference between input and output rotational speed, thus providing the equivalent of a reduction gear. Some of these devices are also equipped with a temporary locking mechanism which rigidly binds the engine to the transmission when their speeds are nearly equal, to avoid slippage and a resulting loss of efficiency.

[@patrikmuller151]

OMG you are baaack!!!!

[@ProjectRedfoot]

good set of bikes you got there

[@wakeywakey4289]

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

[@bumwater3597]

Yea!!!!!!! You're back!!!!!

[@DonovanBryant92]

i cant wait to get my mini bike running i saved it from getting parted out from a big junkyard and it had no motor i paid 10 bucks for it and im saving up for the motor so i hopefully should be able to get it running by next summer

[@justinbriggs9474]

how much would yhe blue one be

[@stefvdiepen]

Nick! you're back! nice job man

[@GeorgiaRidgerunner]

i like it thanks for the upload

[@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.

[@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

[@adrianflores6116]

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

[@eddieknox9874]

got a minibike frame in the junkpile o its way to the scrapper

[@udizzy1969]

Cool Projects brother, Cheers The Dizz.

[@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.

[@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.

[@python357magnum100]

I think that frame had a Hodaka Ace motor.

[@Samdonahue1]

What kind is the red frame?

[@glvlogs3934]

Sam Donahue probably a Jc penny's golden pinto or a sears bike, all from the 70s

[@robertspencer7372]

when are you going to upload more videos

[@ELVISRN1]

I put that motor and the torque converter in mine with no cutting. doodlebug.yes it is tight

[@ELVISRN1]

oblong the t-converter mount holes next time to eliminate the raising of the motor that high.

[@zachprinkey8874]

You should make a video for the cooler scooter thing we started a long time ago

[@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😄

What ever happened to the HUGE superbike engine? Great to see you back!

[@bignickthegreat]

+Nick Svendsen Still saving cash to buy machinery/tools to make the build happen!

[@Rocko892]

+bignickthegreat it'll be great!

[@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

[@redmantv1710]

Dude thats awsome

[@richardhatt6541]

Harbor freight has a 79cc that would fit on the bike. It would have matched the frame better.

[@ralphbenites1819]

I’m pretty sure thay used old edger engines mclane .briggs & Stratton

[@SamReinMotorsports]

Warning might be gas problems with gas tank. I mounted my gas tank under the seat and the engine runs like crap because it gets too much gas.

[@owens8859]

how much do you want for it?

[@tyscanlon4041]

Where can you get a mini nike

[@bignickthegreat]

Craigslist has always been my favorite

[@BuzzLOLOL]

Too bad those Predator engines run backwards, so the cylinder can't go forward... someone needs to sell a reverse rotation cam for them... and reverse ignition timing setup...
