Drag Mini Bike Head Work & Performance Carb

This week, we adjust the wheelie bar on our drag mini bike for better launches, port and polish the Predator 212cc head, try to install a Mikuni performance carburetor, and get the head shaved for higher compression.

Shooting in Ike's shop is a really nice location. I really loved the shot of the ending wrap up. You guys consistently make high quality and very entertaining videos. I'm glad I subscribed to you almost a year ago

[@isaacitllbefine7231]

thanks for watching us

[@edwardtimothytall]

love the length of modification and effort you guys put into these! it just makes me wish I had all this knowledge when I was younger! it's tempting me to build something so badly 😂

[@StevenLeoKorell]

Go Power Sports is right down the street from me. Ever since they talked me into a Predator 212 for my 60's era go kart frame a couple years ago, I've checked out your videos for tips and tricks. I'd like to see you guys on the 22nd and hopefully ask for a couple pointers. Safe travels!

[@schoolsout15]

I got a whole new appreciation for motorcycles and cars in general thanks to you guys. Keep it up!

[@gilbertsprojects2954]

Cannot wait for u to get it put back together and running again... great work guys!

[@07zx14White]

It's coming together nicely guys. I look forward to seeing how the new mods affect your driveway time slip. 15 years ago or so when me and my buddies were putting mini bikes together one of them used a race slick on the rear. It was flat and boxy but he just wanted it for launches and it seemed to help. It was an extremely soft compound. Just thought I'd throw that out there. Anyway, great job guys and I always enjoy watching the fun you guys have with all of this.

[@jamesbrandenburger3476]

thank you guys for your easy going attitudes towards telling us whats going on, great crew. keep posting videos.

[@bgd73]

I like the porting tip. The pause to puddle is vacuum meeting heat. As you learn one engine, it is a small distance behind the valve, all else can be super smooth.

[@dillongee2771]

I live 40 minutes away from there can't wait to meet y'all

[@isaacitllbefine7231]

cool

[@Fullthrottle440Garage]

Good stuff . Keep up the good work guys. enjoy every video

[@GARAGEEP]

Watching from the UK here! Keep up the great content!!!

[@CarsandCameras]

Thanks Sam

[@eryncole6347]

CarsandCameras I touched myself while watching the video

[@digitalbarrito3555]

As always, great stuff, makin mondays better, ya'll keep up the good work and it'll be fine.

[@AmityvilleMustang]

You guys are awesome. I always enjoy your videos and Ike's car collection!

[@CarsandCameras]

Which do you think would win in a drag race: the drag bike, the 670, or the AWD kart?

[@Jackandbear11]

CarsandCameras the 670. Its my favourite gocart

[@GARAGEEP]

The 670 would win all day long!

[@edward6488]

CarsandCameras once the drag buke is fully modded

[@edward6488]

bike

[@arvidlindman7499]

670

[@cbobscountrybunker2312]

I learned a lot about carburetor tunning from one of david vizzard books. To get the best off idle to midrange power. Grate videos thanks for making tv obsolete you guys are awesome.

[@reygar]

The take off on that bike sound really wicked!!!!

[@jok3yjesu339]

cant wait to see it

[@zukislumber]

I do actually learn a thing or two from u guyz once in a while.

[@keithfrisell4271]

Hey guys like ur videos. As for the cam and shaving the head I would check piston to valve clearance! Have a great day Keith

[@johninzerillo1510]

Great video. Neat trick with the air on the hand grip Ike.

[@looneysgokartbuilds8945]

just been going through watching your videos, love em and appreciate the amazing channel, my favorite to watch! you guys are awesome and I'm so thankful for you and all good :), God bless

[@bastarddoggy]

The love mixture of fuel and air is great. The word you're looking for is atomization.

[@javajack9197]

Hope the head comes back soon guys. Looking forward to the next video.

[@isaacitllbefine7231]

thanks

[@garynroe1332]

Weatherford Texas right here!

[@missionDan]

Air in handle bars! Genius!

[@ChevyZ-bw3kw]

luv watching ur videos both this one and ur channel ike

[@nateham92]

yaaaaaaay adjustment of the wheelie bar!

[@duncan9168]

this is gonna be a sick motor!

[@toddcostantino2717]

Been loving everything you guys put out! If I could recommend... find a set of re-popped Schwinn Stingray Crate sissy bars for the top tubes of the wheelie bar. It will give you some spring when the wheelie bar "plants" and will prevent the rear wheel from bouncing up on launch. Also, if you plan on spending some "hang time" on the wheelie bar, use the whole rear skateboard truck and wheels and you can actually steer it with a little "body english" with the front wheel in the air.

[@connorbudsan8920]

Awesome video keep up the good work

[@isaacitllbefine7231]

thanks

[@comixkidgaming4281]

Man the thing is going to be fast :)

[@shark11175]

Love watchin tte old vids

[@kyrovld]

[@joshjarvis4618]

670. All the way that cart is sweet👍 love the vids guys

[@Edgar-and-Wrench]

in going!!! im stationed right down the road from gps :D

[@isaacitllbefine7231]

hope to see you there

[@jackk_tvv]

Mikuni Carbs Are Pretty Good, I Run Them On My 125 Pit And Its Great, Never Had Any Problems

[@trooperandcooperale3057]

Glad you click on to putting air in for the grip. Works also with putting the air gun into the grip it self on the bar. That how bike shops do it.

[@sykwookiee]

Trooperandcooper Ale ...Ikes twin runs a bike shop...for every task, there's several ways to do it...most of them are right...opinions, opinions...have a nice day

[@lucassantefort4137]

I ride BMX, and we use air compressors to put on handlebar grips. It usually works better than Windex, because there is never any lubrication between the bars and the grip. Rubbing alcohol sounds like a good idea too.

[@yousifa6549]

YES, FINALLY!

[@WeBuildStuff]

vice bolted to the table! big changes from a few years back!

[@christickle3160]

love how you representing my town college ELON shout out from burlington

[@ThatDrummerBen]

I put pro taper pillow top grips on my mini bike, and it was the best mod I have ever done

[@shifthappens8475]

Man I've been watching for a while now and never knew you were about 20 minutes from me Haha

[@waceymitchell6786]

"Fuel atomization" is the words you are looking for Ike. Lol.

[@isaacitllbefine7231]

yep. thanks. lol

[@TheRealSmithFamily]

With a rubber grip like that, the easiest (if you have it) is to use compressed air and float them on and off. (SERIOUSLY)

[@Partnerthedog]

Oh wd40 works too

[@1981dasimpson]

i tend to use washing up liquid for putting grips on as it also acts like a glue once dry

[@GasNBullets]

So lucky... Wish I had my vice bolted to a table... Hmmm project day...

[@kita17n]

brake cleaner is the best for installing grips, slide em on then the chems turn the grip into its own glue - just an fyi - keep up the great work men

[@Partnerthedog]

"Fuel Atomization" is the word you were looking for. That's when the fuel is a nice spray and stays misty for the engine to suck up

[@garysetter5328]

If you're not running a super high lift cam and/or stroker crank, .050" isn't too much but now your push rods will be longer and throw off the valve geometry in a OHV. If you want to be sure there's valve clearance, put a blob of modeling clay on the piston top, install the head and spin it. Remove the head and measure the thickness of the clay where the valves hit. If you got .060" your good.

[@1981dasimpson]

on a carbed engine you only polish the exhuast port as the burs and such on the inlet allow for better atomisation of the fuel

[@raveracer77]

For the wheelie bar, if the increased power still over drives the wheelie bar try making the top bracket slide and add a spring and or gas piston as a damper.

[@bdd_dbe]

She got a cam in 'er!

[@Malcolmstuartcole]

Tilt the hbars forward....Loving your new minis....

[@JokerFromHell]

i see that 4x4 chasie behind you guys :)

[@Jomama7272]

Omg, you guys should definitely make a go-kart with handle bars instead of a steering wheel.

[@robertmiller5735]

find some small pair of struts (from a very small light car or bike) and replace the top 2 drag bars . this should eliminate the tire spin . But i feel it is good enough as is .

[@nathanwolff2505]

Can you paint the wheelie bar black?

[@jacobcribbs6284]

Can you guys do a video on internal parts and how to get the crankshaft out please

[@ThriftStoreHacker]

can you adjust the stall rate on the torque converter to make it engage at higher rpms?

[@speedbob712]

With such a small area you can use sandpaper glued to a flat surface and some elbow grease. you know, on the cheep.

[@FireAndGasoline]

CarsandCameras mini bike VS FireAndGasoline mini bike!!! LET'S RACE!!! Both have same frame, torque converter, and sprockets just different engines.

[@rednecklife-uu3je]

Get em bro!!

[@FireAndGasoline]

Hell yeah! 9hp vanguard stock Vs Modified predator 212. We need to find out if there is or isn't a replacement for displacement.

[@dbd1317]

8hp flat-head briggs does the job

[@FireAndGasoline]

DBD yea but we gotta work with what we've got. We did pretty well and everything including paint was under $150. It's FAST!

[@dbd1317]

Yeah what you have is nice. Wow that price is amazing! Our engine and frame were free but but we spent close to that on a clutch, chain, and a new rear tire. Never found the top speed, ~50 mph on a mini bike gets sketchy.

[@anonymouscyclist1233]

mods for the drag minibike, for traction a square section tyre? how about a little nitrous kit too?

[@SamReinMotorsports]

I have a fully built 212 predator. My mini bike can easily hit 50 mph. I had to slow down because i ran out of road. But it was still puling when it hit 50.

[@ClumsyCars]

i took about a 16th of an ich of my 12.5 briggs flat head and it ran fine. it run hot but i never adjusted the timing. strong motor though, lol. oh yea, i did this by hand with sand paper,a glass table and soapy water and elbow grease.

[@jpollard1984]

Lol I know exactly where that shop is. My parents bought a house about 15 mins from there. That’s pretty cool.

[@speedstergarage6393]

You can put clay on the valve and turn it over a couple of times and then measure how close it is with some calipers. .0050 won't be too much. I took .0085 off of my Chines clone and it still has room to go more but since yours is a hemi it could interfere differently than mine. Can't wait to see how it turns out.

[@Dec4ption]

yall should have a meet and greet in north carolina! i live there too and could actually go! haha

[@isaacitllbefine7231]

we will be at the charlotte auto fair this weekend looking around

[@philtripe]

cant wait to see how the motorcycle carb works...ive been saying for years those motors would wake up with a good carb but now im having some doubts, like what if the timing doesnt advance enough to take all the extra fuel...do these things even have a vacuum advance? without any kind of advance it would be difficult to get more speed out of the engine

[@irishokie2319]

I have a yerf dog and have measured and a 670 will fit in it with a little modifications to the frame tha would be cool to see

[@williamscott9206]

I think the drag bike will win!!!! go drag bike!!!!!!!!!!!!!!!

[@joebartell3656]

hair spray is the best because it dry and it gets sticky so it makes the handle bar grips stick the the handle bars

[@Revdonlee74]

Yer' gittin' wheel spin cause of those knobby tires, ya need a slick on 'er. What cam did ya's put in it?

[@noahkline6042]

When will y'all work on the all wheel drive go kart

[@36thgallardo]

A thought I had on a wider rear tire - maybe if instead of one wide tire there was 2 smaller slicks on the same rear axle and the chain + sprocket went inbetween them? That would probably still require frame mods but maybe it wouldn't require as much engine relocation. Even if that's not the most practical solution it'd be interesting at least.

[@wademckenney6858]

man i wish i lived closer i want to go to the meet insted im way up north

[@buckykattguitar]

Have you thought about seeing if there's a go kart slick tire that'll fit the rear rim? That should give you the traction you need.

[@BlakJak]

I live an hour away and I will see you there!

[@cootersgarage4408]

Will the 212 engine fit in this bike with the factory gas tank on it? I picked one of those bikes before the swap meet.

[@voltron63]

HEY red beard's garage . has a small nitrous kit for the 212 predator...

[@robertbronson5248]

Young Skywalker really has to work on his headful anticipation.very funny trials

[@walkerlandreth4761]

how can i determine what size carb i would need for a 6.5hp briggs and Stratton engine?

[@Puffalupagus360]

for a cheap intermediate Better tire i would recommend a Carlisle Turf Saver II 20x8.00-8

[@mworld]

Can you get a carby with an accelerator pump on it for that engine ?

[@andrewwilson8317]

Put foot pegs right far back on the wheelie bars and extend handlebars much more forward and down. Get down prone on it! Less drag=faster top end.

[@austinroussel8615]

carsandcameras what shop did yall send yall head to because i'm doing a mini drag bike

[@jamest.5001]

what happened to the little turbo? you guys had on a cart. I haven't seen it in a while.

[@redeye850]

atomization = a love mixture of horsepower

[@stevewilson2745]

the head on your predator motor has built in rocker mounts? mine has the stupid studs that break off if you even look at them wrong lol. which reminds me, i need to order yet another set..

[@crazzyzack]

What you need next is a pocket bike nos kit for it.

[@Edgar-and-Wrench]

did yall remove the gov before installing the mikuno

[@rolandzurillo7758]

The southerner does all the wrenchin

[@dylanwestbrooks8016]

15:30 use zip ties I use like 4 to 5 when you put on the grips it works really well

[@mikaelhgn1]

You guys need to do a meet up in NC

[@isaacitllbefine7231]

we are going to be at the charlotte auto fair this weekend looking around

[@butchs.4239]

That's cool, are you bringing any of Ike's Rides out to the show? I'll be out there both days, hope I run into you two.

[@Ben-rm9jx]

how about change the rear sprocket

[@bobaganooshy]

wow I figured you guys would just set the head on a belt sander

[@isaacitllbefine7231]

we have but we wanted this one rite

[@TheAmericanUhate]

When are you going to do a smog pump supercharged go-kart??

[@chriss8206]

John is the most awkward person on two wheels I've ever seen. Love when he kick starts something he jumps off the ground. And when he drag races his starts look like he's taking a dump. Lol

[@th3ragegamer56]

To think this was 4 years ago is insane
