We bought an $80 Flea Market Mini Bike and Turned it Into a 30 Horsepower Drag Racing MONSTER!

We turned a dirt bug mini bike (similar to a doodlebug mini bike) that we bought for $80 at the flea market into a drag mini bike! We installed a jr dragster front wheel and tire, a go power sports live axle kit, and we built a tillotson 236cc racing engine.

Thanks for the invite, boys! Had a blast working with yall on this mean mini!

[@CarsandCameras]

Engine build AND bike build in one episode? Heck yeah! Apologies for the late upload!

[@dynamite6507]

Yea were mad about the free content lol

[@kevinsellsit5584]

I don't want to put a damper on your beautiful dad engine building moment, but it is critical to have the dowel pins installed when checking your clearances. It is far less important when using that awesome cnc machined cover, but with a factory cover the dowels ARE the locator and the cheesy stock covers have huge loose fitting bolt holes. Otherwise a spectacular teaching job and a wicked sounding engine. Hang on tite!

[@dbomber69]

Port matching gets rid of the "Speedbumps".

[@JeffKopis]

Worth the wait!

[@JeffKopis]

I love these traditional style, old school minibikes. Like I had over 50 years ago! Small frame, small wheels, no suspension, tall skinny bars, and in the old days a 3hp Tecumseh or Briggs. Not the monster engines they make now!

[@pollyg562]

im bedridden and bored Over an hour episode is exactly what I needed

[@WyFoster]

Feel better my man!

[@Backend_Goat]

Hey guys @carsandcameras! To prep a methanol motor for storage you don't need to clean out the carburetor. Before the last oil change, shut your fuel off and then pull the fuel line. Start the engine up.. once it starts pulling the remaining methanol in the the line, submerge the fuel line into a bottle of Marvel's Mystery Oil. When the oil starts being pulled into the carburetor, give it slightly higher RPMs so that your engine doesn't die. It will run very boggy until all of the fuel is completely gone from the carburetor. Now your carb and all fuel components plus your cylinder and crankcase have all been lubricated for storage all in one swoop! Hope this helps!

[@Killerchicken10]

I do the same thing to my engine I mix mine 50/50 gas and marvels mystery oil

[@RRRIBEYE]

Rumor's been told that to this day, even Derek at Vice Grip Garage doesn't know what's in it! *IT'S A MYSTERY!* 🤣

[@andyredvolvo9434]

😂😂😂​@@RRRIBEYE

[@garychandler4296]

Well, it was made as an upper cylinder lubricant, back when oils didn't have our modern detergents, lube modifiers, viscosity control, etc. It's not necessary anymore, but the storage idea is great!

[@craigbowley6783]

That odyssey is sitting there just waiting for a hyabusa engine 😁

[@Ratkill9000]

I kind of prefer these later upload times. Home from work, get to kick back and relax!

[@joshuagibson2520]

Like you can't save and watch it anytime you want.

[@Ratkill9000]

I prefer to watch these in one sitting. And also like to comment within the first few minutes as well.

[@ohcopp]

Exactly!!

[@mathieulachance151]

Exactly

[@zippythinginvention]

The thought of pushing those forks at 100 miles an hour is more than vaguely terrifying.

[@flybik3es]

Really would love to see you guys build a old school style chopper mini bike from scratch .

[@Thesilver_6pnt2]

this would be awesome, id love to see a clean mini chopper build from these guys

[@carlowens3424]

First late drop has people’s anxiety heightened 😂

[@shiftymiata]

Switching to weekly uploads was such a good move for this channel, these videos are Incredible. Absolutely love the longer format videos like this with higher production quality, can't believe we get this content for free. Love you guys

[@brandonmorgan3772]

Well John knows as much as my wife about building engines Good thing for Ike and Google

[@kainthepain7126]

Is it me or is John getting a bit sassy.

[@xxIONBOMBxx]

For real He best put respect on IKEs name for real

[@roodick85]

Ok yeah I noticed that too..getting a lil too big for his britches

[@greenbassboosts8872]

I noticed years ago that this channel had a slightly gay vibe to it....? I don't care lol

[@seivaDsugnA]

Yes.

[@seivaDsugnA]

Yes and no.

[@rekik66]

Laying down some aluminum foil under the drain plug helps direct the oil a little better. You can shape it. I saw it on KZbin. 😂.

[@keithhasafastcar]

Are we ever going to get new kart build videos again? Or is this strictly a mini bike channel now

[@3v068]

WOOOOOOO!!!!! Much love from Texas guys! Austin area here and we love ya!

[@darrellnichter9894]

Hell ya I can't wait!

[@williamstamper442]

In 2019 i bought an exact same stock doodlebug in brand new condition for 250. It instantly got a 212 HF and a torque converter and i was hooked (again) as it had been over 40 years since my last mini. In no time at all, well by the next summer, it goes 8 50s @74 with relative ease. These are so simple and fun. Wheelie bars are a must for cvt torque-a-verter minis if you wanna go quick. Mine carries the front for at least the first 100 feet on the bars. Had a hard time at the track at first trying not to red light beause the tiny front wheel was going up and over the beams. Eventually I figured out how deep to stage and figured it out. I later built an identical doodlebug with nearly the same mods but it runs a hilliard inferno centrifugal. Very interesting testing both minis with only difference being the clutch and drive system

[@nszabados]

hell yeah the good ol doodlebug! such a fun little mini bike

[@1panther32]

This is the exact color of the first mini bike I ever built I started watching you guys to learn how to build it

[@user-gt3xx6lc1o]

I watch these mostly for entertainment but like to see you get more involved. I've learned over time to use an old main bearing that I grind down the od of of for easy removal and install to use for test fitting and 1st assembly of almost everything. Then I don't worry much about dirt and dust early on. I also don't put rings on.at this point - that lets me feel binding or tight spots easier. Then I disassemble everything, deburr, everything, remove bearing and scrub block in hot soapy water multiple times!!! Wipe bore with oil, install new bearing and seal and assemble. Once assembled put oil in and roll motor around every day or so and again when installing and you'll know oil is everywhere. Also, my theory on push rods is rocker should be level with head, and tip centered on valve tip at 1/2 of valve travel. That makes for the least stress on valve train in my eyes. Cool video!

[@quevicular]

Micro cart all the way guys. Next project!!

[@Dazg297]

Great video can't wait to see it rip up the track good luck guys

[@Wil_Liam1]

Actually,if one nicks the cranks rod journal that crank is still usuable as long as the nick is recessed, or emery emory cloth smoothed and polished back up as a slight depression is fine as the crank and bearings do not actually touch one another when the engine is running.. Thin layer of oil separates them and all you've done is create a place where extra oil will fill in... I've seen and built many engines with cranks that had marks and they've lasted 1000s of passes,laps,or 100s of 1000s of miles... Small nicks,or scratches yes,but not 1/4" by 1/2" trenches...

[@randallmartin9108]

Really like this format. Been watching as a enthusiast of engineering I follow you as I do grind hard plumbing keep up the good work

[@ni_wink84]

You don’t have an oil pump so Ike’s plan to go with assembly lube is definitely the way to go, btw boys I may be wrong here but “lapping” flywheel is for making sure the press fit is exact, not for the binding effect exactly, we do the same thing at the machine shop to make a balancer fit, we hone it slightly so press isn’t too tight or too loose, just my 2 cents

[@WyFoster]

The rod literally goes below the oil level in the crankcase. Assembly lube is pretty much pointless on these engines. You don't have to wait for oil to full up passages. It's instantly splashed on the first revolution. Just saturate the parts with the oil you'd use and you're good to go.

[@Skiridr22]

Love these videos, learned a lot frm this episode 👍🏾

[@racerothery2716]

That’s a dope, I did a 32/25 head on mine too but I bought mine from EC which was already smoothed out inside so I never had to mess with it. It had to be though because they sell it with the seats and valves already in it and I just replaced the valve springs and retainers with 55lb or 60lb dual springs. Oh and I got you beat on the black venoms because I got the 1.35 😂

[@25_mason]

Holy awesome guys, your builds are awsome

[@smenginemech]

I was waiting all day for a video

[@coopcommunityllc]

I bought the same one right out of the back of a guy's truck for 60 bucks 2 years ago it was just red but it was a doodle dirt bug. I bought a 79 CC threw it on there for my son and he loves the dang thing. Does about 30. Love the channel benefit all the way back to the rat rod wagon 💯

[@williamstamper442]

I see near the end you swapped a set of stock mega moto style handlebars. As hard as ive tried to make them work, just can't seem to get drag bars to work on a doodlebug. They hit your knees and put you in the most awkward riding position ever which won't even allow you to make a pass. Both my drag doodlebugs have either the one piece fork bars like stock or a set off an old bmx bike from the 80s. Ive even tried flat drag handlebars with 6 inch risers and nope just can't get them to work. This whole build is right up my alley boys. Been watching this channel since early 2017 and love how y'all have kept the same vibe over the years.

[@axoricgaming4873]

Love Yalls Content

[@JohnHill-jm7tm]

WOW 💪. What an awesome video 👍. The only problem this Old Man from Washington NC had to watch it on my phone 😭. Internet down again so no 70 inch TV. Always looking forward to your videos. 🛵🧔💝💝

[@hatchethut]

Nice job guys that bike is rad!!!

[@davidkallstrom4349]

great video

[@waynesart8385]

Uncle Ike strikes again😅

[@sadik5945]

Finally a minibike video🤘

[@craiggiles8156]

Feature length fun. Great build lads.

[@elisomers8819]

That was first ever mini bike I had

[@lucassarchet6712]

Nice work, fellas! 😮

[@Joshers2077]

Just saw the shelf of beans fits in perfectly

[@skinnyswheelz5330]

Perfect!

[@caseyhatfield1017]

I noticed a swap meet Honda Oddysey in the background!!!!

[@lukecombs5242]

I’m stoked that you guys bought the fl350r odyssey 😊can’t wait to see you guys ride it they are a blast.

[@lx1402]

Nice welds👍

[@mathieulachance151]

I love the intro of your videos 😂 they never fail to make me laugh.

[@jonathancrissinger2301]

Watching you guys at the track is going to be awesome. That is one wicked machine. Good luck and be safe. I will see you later.

[@kaiosobreira]

i really wanna see a video on that blue car

[@michaelb.42112]

I had no idea mini bikes were on the rise. I'm 55 and in 1979 in 5th grade I used to go to the library nearly daily to look at the book, "Minibikes" and dream of owning one. I ended up buying a Honda XR80 and I was the coolest kid (to me, even though I was still a total dork). EDIT : WOW $80 for a running minibike !

[@Ty-bz7zx]

Far from running.... was rusted out & locked up. The opposite of running.

[@daledodson4368]

I can say for a fact this will hold 450 lbs easy. Me and my buddy used to double up on one of these in highschool and ride around our town took everything we threw at it to the point I had a rope to start it and a MTN dew bottle as a gas tank for a bit but then I tore it down gave it full suspension and Honda xr100 motor but sadly while waiting for parts like a new tank and seat someone threw it in the scrap 😂

[@williamstamper442]

Hey ike, around 1:31:50 when a fresh engine gets hard to pull ive found the valves need to be lashed again to whatever spec you wanna run, especially with a little heat in the motor. Hot lash is even more important than cold lash. If you run the valves i bet it pulls like butter...lets see what happens...

[@jammin-w-joseph.musicvideo9494]

Great episode guys!

[@Bikescameras849]

Great job fellas

[@shanewright6958]

Another great video guys 👍👍

[@2015-Koenigsegg-agera-rs]

This is the bad ass stuff I like to watch

[@crowtubecrozier2857]

Good luck, great cool build

[@BruceLyeg]

I've got two Dirt Bugs and they're my favorite mini bikes. To me they're the quintessential mini bike. One of mine has a 302cc on it, the frame doesn't flex as much once you're sitting on it

[@Robert-ni6ut]

Man you guys did a great job building that engine it sounds awesome ❤👍

[@Greg1096]

I used to be super careful with h engine builds like that, though that was before i had pulled multiple siezed motors out of the junkyard broke em loose and had them run for years without being opened up, they arent as sensitive to dust and dirt as you would think, bow of course its not ideal to run a ton of shavings or dirt through a newly built engine but it also isnt going to trash it like some engine builder lead you to believe either.

[@PatrickTolmie-fe1ty]

Have a good time guys and as always be good be safe

[@darellsimons2687]

Amazing build

[@junkinstein2856]

Death trap should be this one’s name 😂 and make a small boat from the 79cc kne of those like long tails with the king shaft drive

[@GratefulEd907]

When I picture a mini bike I picture a doodlebug

[@rong4189]

2:17 Haha Ike, I saw it, I feel ya man!

[@Razor6On3]

I mean credit where it's due, but john is really riding that Paul dude's shock.😂

[@Raynerbart]

That's sweet I might do that will mine

[@ezraskope5997]

Excellent Content

[@NotMeeither]

Just a FYI I never put lube on a shaft where it fits in a ball roller or needle bearing unless the shaft also acts as the inner race .

[@daleosborn3729]

Amazing video.

[@DIYWilly]

Guys.. I wish you would have got it together enough to make a run around the Grand Prix. Yes I know it would have been at the bottom of the leaderboard but would have been really cool. You guys don’t have a 79cc on the leaderboard. Thanks for sharing!!

[@Dusky_The_Husky]

You turned it from the Doodlebug, to the Doodle Bob... Me Hoi Minoy... XD

[@philiprowney]

[ yes, I am a pedant, an Autistic one :-P ] 35:00 - Fugal, petal means inward... ED To avoid in future, just say 'angular momentum' it's science. NB Look up Centrifuge and it's purpose for a reminder.

[@simonpaul9795]

I like the longer video

[@drblakeslovick4607]

I'm super late to the party 🎉... A channel who takes there time with builds. 🏆😁 I got rid of cable TV. This is amazing. Appreciate these long form episodes. 🍻🍿

[@JR-Rollin]

I like your buddy's idea of supermanning it. I'd weld some pegs off the back or off the wheelie bars so you can lay out like a drag bike, so your not so squished up...definitely would be better for aerodynamics and way more stable when hitting high speeds for sure. Or just drag your feet off the back at least, to be more stable. Just my 2 cents... Love the build though, that thing looks sick too. 👍👍

[@wurthmannd024]

Those amazon electric transfer pumps are amazing. still running the same D battery mine came with 2 years ago. Fills my kerosene heater in the winter, and my boat in the summer! haha

[@REALISMMODSAC]

sick video watched you since i was 13 im now 20 hahaha! learned so much from you and front axle forks setups same on my pw80

[@theonlydemi-god7858]

Never napped so good i actually enjoyed this ran it back and all

[@sandmanbub]

Extended forks also help keep the front wheel down during hard acceleration (drag racing)

[@Youngster69420]

Fastest way, I learn to start an engine, take the spark plug out, put some brake cleaner in the head and put the plug back in and pull

[@Youngster69420]

Starts every time

[@c.a.mcneil7599]

I remember as I kid that had a bonanza mini bike. We would shove stuff in the centrifugal clutch at the top of a hill get her going again. Yes that was after losing interest in lawn darts. But what’s funny the teacher in my wood shop lost a few of his fingers. What a great teacher of wood shop. Some may think he learned a lesson. I say he is why there is a warning not to replace a fan belt while motor is running.

[@Jay-lc1nh]

Ike (23:30/24:50) Just easin' the tension, baby. Just easin' the tension! Lol. Carl Weathers/Happy Gilmore. Great job guy's.

[@shk2564]

Best of luck! 🤞

[@jasonjgr8580]

Cool build , it would be cool to see a revival of the cross cart I believe it's the one with the honda motorcycle engine.

[@sandmanbub]

I wanna see Captain America's mini chopper. 🤗

[@ManiacRacing]

Slitting the fork tube wont make it stronger. Just weld the axle plate on from both sides with full penetration. Cutting a slot for it weakens the fork tubing a LOT

[@user-cg1ki9gt4p]

i will always like a movie. hell yea. thank you people.

[@WyFoster]

Let's go boys!!!

[@xpndblhero5170]

It took me an hour to realize that the video was and hour and a half long.... 😅😂 Edit: You should put a drain tube through that engine plate... That's kind of ridiculous to get oil all over such an awesome bike. I Love the Paperboy look at the end.... Well Done Guys, well done. 😁👍❤️

[@charlirmartin2981]

Ike reminds me of my dad and John reminds me of… me 😂 we ask the same questions and get the simplest answers, “ use your finger and just * swoop air noise* “ 😂 love the vids guys I’m 17 now and I’ve been subbed and watching since my 13th birthday when I got my FIRST mini bike 😁😁😁

[@65BAJA]

Buddy and I just got an old kart. Yanked the Briggs off it and threw on a Predator 212. Got some issues to work through but it's a runner now. Floor pan need to be rewelded. It's 1/2 hanging off. Need to rig a return spring for the throttle. Also needs a spacer plate to raise the motor a but to tighten the chain. May end up extending the chassis 4-6 inches too.

[@kylestuppy5908]

my birthday is the same month and day as your connecting rod lol thats amazing

[@hunnybunnysheavymetalmusic6542]

Waiting to see the continuance of the development of the DRAG RAIL!!!

[@ontariofishing1790]

Debate time! Smooth bore intake Or Dimple intake to allow the golf ball effect. Or swirl intake to improve the squish and swirl of the fuel air ratio for superior combustion

[@whatsinanamethatthecaptive577]

I hope the frame does not flex too much when you test it on pavement with some traction. Can't wait to see it go down the track.

[@Anthony23585]

You guys should take a off-road gocart upgrade the suspension and put a motorcycle motor on it for trail riding

[@Skiridr22]

Its even more satisfying when nothing is hitting 😊👍🏾

[@bren42069]

my first engine build was a zeda 80 firestorm, a bicycle 2 stroke. it's a good beginner engine, you'll learn a lot, and there's no valves so it's pretty simple. 200 bucks for a whole ass kit good luck fellas, that's a nice lookin build

[@greenbassboosts8872]

It's always surprising how well am little 2 stroke can run. I wish the 49cc pocket bike engines had a robust trans on them like the bike kits... They have a flywheel fan cooling them and the bike kits tend to get hot. Otherwise, an eBay 49cc (40cc ish) engine is only $43 and there can be mods done to learn on. I have one, runs ok but needs a bigger jet out the box

[@murrayminimotors1674]

Sweeeet video thanks 😊 🙏🏾

[@motorhead1884]

I just did a similar thing but with a 20 dollar scrap yard find I've posted a couple shorts about it
