Insane Carburetor Project!!

Insane Carburetor Project!!

Just. For the heck of it I'm gonna polish this carburetor to a mirror shine now. I'm not usually a fan of polished aluminum but I think it would look cool on this carburetor now it's been about 10 or so years since I've brought aluminum to a chrome-like finish so. Bear with me as I knock, off the rust so. There's a few things I want to pull off just to make the polishing, process a little bit easier mainly. The choke a few, of these screws and the. Cable guide up on top. This. Is what I'll be using to knock out the polishing, it's got a little electric, dremel tool along. With the accessories, that came with and then. A crap ton of other polish and supplies I've had around the shop alright, roll up your sleeves boys it's about to get dirty the first attachment I'll be trying out is this little cloth wheel and also. Supplied in the kit was, the stick of polishing, compound, and with any grinding or polishing project, you gotta wear a respirator. I'm. Starting, to realize this is gonna be a ton of work a lot more than I was hoping for it, wouldn't be bad just polishing out the football, but the carburetor body itself would need to be sanded down because, it's got this casting. Texture, on it and all that would need to be knocked down in order to polish it out to a mirror shine so what I'm gonna do instead is pull the carburetor completely, apart polish. The football and the, throttle cap and then. Seracote, the carburetor body this, should look pretty cool. Now. I've got the carburetor completely. Apart it is gonna be so much easier polishing. Out the football and throttle, cap over on the buffing machine first off I'm gonna clean up these two pieces with, a scotch brite wheel and what, this is gonna do is remove. Some of the scratches, smooth, out the finish and get it ready for the first stage of buffing. I've, got some ridges here on the edge of the football and some deeper scratches that, I'm gonna take care of with the sanding drum. The. First stage of buffing will be with what they call a sown wheel and a. Triply compound. So. The wheel I was using earlier this one right here actually is not a stone, wheel this. One on the buffer is indeed I came across it in the cabinet and it seems to work a lot better a little more aggressive after the first stage this stuff is starting to take shape, but you just wait until the final stage is done and that will involve using a loose style wheel along, with a white Rouge.

Not, Bad at all it's gonna clean up some of this buffing compound may. Be touched up a little bit and then call again well, guys I am gonna have to call that done polishing, definitely. Is not my strong point these. Things did not turn out quite perfect, but. You know what it, was a fun little challenge and I think it'll still look pretty cool all put together next. On the list is prepping. The carburetor body for sarah coding if you guys want to see the entire sarah coding process explained. In a video just, click the circle right up here in the corner so basically, the sarah coding process is first. Starting. Out by soaking it in acetone for, 30 minutes then Sam, bossing it followed up with a preheat, at 300, degrees for, a full hour then. Spring up the seracote and then. Curing the seracote back in the oven for another hour. Since, there's a few areas that do not want a sand blast or seracote I'm gonna have to do some masking here. That, was actually a whole lot of masking I don't, know why I've always enjoyed masking, though next, up is Sam blasting. I. Went. Ahead and touched up some of the masking since parts of it were peeling up from the sandblasting, and I, wanted to get all the sand out of the inside of the carburetor one. Thing I need to do before I run this part through the oven is cut. Some slits here. In the masking tape that way doesn't shrivel, up in the oven. All. Right I've got the carburetor hanging, and it's ready to go into the oven for the preheat process, which will burn off any remaining oil and residue. This, is what it looks like when you don't cut enough of a relief into the masking tape it'll. Shrivel, up in the oven once. I fix this it'll be ready to spray uh-oh, as I, was masking, I noticed there's some oil or some sort of residue coming out around these screws so. That's an indicator there's still some oil or something, left in the material, and that'll. Have to be removed before I spray, so, I'm gonna wipe it down with acetone, once again and then bake it in the oven for another hour now. I've got a lot of oil coming out of these screws so I'm just gonna pull them out and wreak, lean the whole carburetor, completely. Frustrating. I'm. Actually glad I went through and pulled this thing apart a little further now. I know 100% is, not gonna be anything leaking out and ruining that sarah coding so, now we just need to soak it in acetone mask. It off again and then, preheat. It in the oven and it, should be all ready to spray after that finally. The carburetor gassed out fine and there are no signs of any oil residue, time. To mix up some seracote and spray, out the carburetor so. I've got two seracote colors here, a burnt, bronze and a tungsten and I'm having a tough time deciding, between the two I know, I can't go wrong either way but, just, hard to know without having an actual. Part spray it out with either color in front of me. Hmm. I'm. Thinking for this carburetor a bronze, is gonna stand out more the. Tungsten is kind, of like a charcoal, color so. It's not gonna be like, that far off of what, color it is already so. I'm just gonna go with the bronze. All. Right I've had the carburetor in the oven for an hour now and it should be all cured, and good, to go check. That thing out for. You guys I love the look of seracote and want some work done make, sure you get a hold of Clayton over, at trick engineering, super. Good guy he'll set you up with some really good pricing and work I'll put his info down below, all. Right I've got the carburetor in a million pieces and it is now ready to go back together, thankfully. All Balls Racing sent over a carburetor, rebuild kit and it looks like it's got everything, I need to completely, overhaul the carburetor all.

Right Let's get this thing back together a lot. Of times my projects, don't really go to plan throughout, videos things, will come up I'll have to shift things around but. There's always a workaround, I just, hate given up on a plan or a project but, with this carburetor I think, it would look pretty cool I'll polish it out but. It should look even better with the sarahx coated body and polish. Flow bolt and cap we'll. See how it turns out so, it should be pretty straightforward bolting. This carburetor back together the only thing I'm gonna walk you through is setting. The float height. So. How I'm gonna check the float height on this carburetor is by setting it level and letting. The floats extend. To their full length. So. They're the art extend it all the way out and. Then. I'm gonna let the floats return to the resting position so. Right there, so. It's not pushing, in the, needle or the valve just. Resting, right up on top of that plunger so, when I push the, floats down, that. Is compressing. The. Plunger. On the, needle valve there so, we want it resting right up on top so, I'll do that once again. So. Right there it's, at its resting, position and if. You can see there's a line on the floats here that, should be parallel with the. Football, line right here on the carburetor so, when the floats are in the resting, position right there we. Need those two lines parallel so. This one is just slightly off and to. Adjust that I'm gonna, bend the tab on the float just a little bit so in order to get the floats level with the football surface I'm, gonna have to bend this tab right here the tab up the needle valve is hanging from I'm. Gonna Bend that up just, a smidge. It. Really doesn't take much to, make an adjustment here. All. Right now let's check it again. So. That is looking pretty parallel right there I'm gonna call that good so, if your float level is too high meaning it's right about there you'll. Need to bend that tab down instead, of bending it up setting, your float height is something you definitely should not skip if, your float height is off it'll pretty much nullify, any jetting, changes and it'll. Really affect, the way the bike runs so get it right the first time. You. If. You guys would like to support what I'm doing with this channel I actually, just got some more stickers in stock head, over to prime Memex comm and grab your stickers. So. All balls provided, a new needle with this kit and I'm gonna go ahead and set the clip position, in the. Same spot as the original one so, this one is one, down from the top and how, this works is if, the clip is farther down that'll, richen it up and farther. Up will lean out the bike. A. Lot. Of times new o-rings don't really want to stay in a place so. Applying, a little bit of grease will help that out and this is where the mini grease gun really comes in handy I can. Put the grease exactly, where I need it and I put a couple dabs, on. This cover here. Of course. I'm gonna have to pop the cap off to get the thrall cable on but, I figured in the meantime might, as well see how it looks and steal. The carburetor up a little bit I also, got a new air screw as well I'm, gonna go ahead and install, that now. So. The factory, setting for the air screw is one and a half turns out from, lightly, seated, I'm.

Gonna Turn, this thing all the way in until it seats and then go one, in half turns out alright, right there is seated. All the way. You. Go half one. And, one. And a half and so what the air screw does is it controls the mixture from closed to about eight turn, to the throttle ideally. With this two-stroke carburetor you want to be between one and three turns, out if you're, below one turnout you need to go larger yep, larger. On the pilot jet and then. More, than three turns out you want to go smaller on the pilot jet and that last of all we have the throttle stop screw this. Is what controls the idle. And. This. Screw needs to be set with the engine running so I'm just gonna set it about. Where it was when, I pulled it apart and that. Should be I, want to say like two or three turns out alrighty, guys that is gonna be it for the carburetor assembly, turned, out absolutely wicked. Definitely. Happy with it. Real. Quick just gonna pick the winner of the giveaway from, that last video go. Ahead and tally, up the comments here looks. Like we've got 373. When. I hit start it's gonna pick a random comment. From that video. All. Right Tyler, Reece says, Honda, right, on man, all right Tyler message, me with your, shipping address here on YouTube and I, will get this master, cylinder kit over to you hopefully you can use it, if. You guys enjoyed watching this, carburetor get all decked out make, sure you smash that like button all, right thank you so much for watching everyone. You.

If you're curious about any of the supplies used throughout the video, I have them linked in the description. Enjoy guys!

Hey Cameron, do you have a clue why the throttle turns and get stuck? The one in the carb, not the Throttle grip. Dont know what its called in english

Now it looks better than new...

That was awesome man. I bet no one else on earth has a carb looking like that.

Cameron Niemela nice video my friend

Je crois que tu as cramé le joint du puit d'aiguille au four...

Your works always look amazing once finished and that carburetor was no exception, I'm anxious to see how all the parts will look in their place, greetings from Guatemala


This would be cool on a CB750F/CB900F/CB1100F based RCB/RS1000 replica - the original Keihin CV carbs on the '76 RCB Endurance Racers were sandcast MAGNESIUM - I've heard they were something like $5000-$6000 for a rack of 'em, and that was in '76-'77 dollars! UNSANE - They charged a lot of $$$ for the works parts in those days! So I've always wanted to do a proper REPLICA of 'em, with that whole "MAGNESIUM PASSIVATE" tint on the carb bodies. They're not the only carbs used on these bikes, maybe not even the most interesting 'cause after all they were functionally similar to the street-bike carbs. Meanwhile there were plastic LECTRON carbs used on some of AHM's AMA Superbikes, there were Keihin racing carbs with clear float bowls, there was a ton of very interesting carbs used on the RCB's & RS1000's - But the fake Magnesium "works replica" project might be about the cheapest "race-replica" carburetor mod you could ever do with these bikes. They had some interesting multicolour "KEIHIN" stickers on 'em too, so of course you'd want to get a batch of those things printed up somehow. Could be awesome though, imho.....

The carb project looks exceptional ... Excellent work


Hey, love your vids! BTW the "choke" is actually an inricher

lol i knew you would change your mind about polishing the actual body its way too much work! Awesome job though the cerakote was a great idea!!

I order from all balls racing too

Hey have you made sure your new jets are the same as what was in there, if it was jetted and running good dont change it lol just my advice :) love the vids such melow vibes

I need that exact carb for my dirt bike do you sell it? Or can you find me one? Ill buy it from you thanks! Btw nice video keep it up

This was like porn to me. Fucking great job man!

Haha thanks man!


Man thats nice good job!

Why didn't I paint my carbs this color

Very nice, great work! Super satisfying to see

Check out kapton tape, it's resistant to heat and used in electronic circuits for insulation

That is insane man!

I don’t see a point in this cause it’s just gonna get dirty again


Cerakote the whole engine

Hey awesome video. I have a Yamaha pw50. I am using it as a pit bike. Here is the question. The cases are Black. What is the Best Way to get the paint off and make the color like other Dirt bikes. I am not sure What the color is called. But the color that is on your 125. Should i sandblast it? Paint strip or What should i do?

Cameron Niemela ok Thanks man

Thanks! You could use paint stripper or just sand blast them.

Just curious how much weight all this cerakote adds

The coating is very thin, so just a few grams for something like a carburetor.

Parts look awesome specially in that bronze color. How would cerakote hold up to hubs or rims?

I love the bronze color. Yes it'd be great for hubs, but for rims it would wear off over time like most other coatings.


that is a sexy carb!! I hope to see this cr250 all built up soon.

Cameron, you've outdone yourself this time!!!! That is incredible.

Thanks! Yeah this was a heck of a project.

looks amazing, i like the two tone better than all polished out

polish those torx screws where the oil leaked ;)

im a fan of surface finishing (i know sounds weird :D). left a sub.

Thank You!

amazing work

This is the best approach to repairing a motorcycle, I will also try to shuffle up, but in Russia there are no such materials, where you can order them from the US?

Cameron typical video, *see an ultra clean part "this thing is pretty dirty, let's clean it all" hahaha, love it

Haha true!

im excited to see whole bike and i am very happy that i finally found out how to adjust needle valve, i had a lot of problems with it. Also it was interesting what you say about jets, please tell about these things more. Thanks

I'll be sure to do a video on jetting!

Your videos are so good! I have learned so much how to work on a bike and maintain it. Keep up the amazing work! Thanks a lot.

Thanks for watching!

That is one sexy looking carb! Never seen any like it before.

Hope that carb runs as good as it looks.

If you carry on like this the finished bike will be to pretty to ride.

This is porn

Very nice but you should have cerakote the drain plug

When will this bike be fully put togetor I can’t wait to see it

Hopefully soon!

Can't wait to see this bike up on the track !

Oh yeah that's going to be fun!

The engine will be finished this month?


I think those screws that u sandplasted will get rusted :/ But the carb looks awesome!

Get yourself a can of 2K clearcoat and clear the polished parts... otherwise they'll tarnish within a week.


That is a very impressive job, Well done. I'm really looking forward to seeing the finished result all put together.

Thank You! I can't wait to put it together

Great job

are you finnish-born?

Cameron Niemela torille

My grandparents are from Finland. I was born in the U.S

Are you going to do the engine the same?

Going to be doing something special that's for sure!

Kick ass work

What is the best supplier for carb rebuild kits?

All Balls Racing

next video about cerakoting the piston rings

Are u just cerakoteing everything so u have an excuse for every part to be spotless

Haha yup!

can't wait to see this bike

Do you still part out bikes? I loved that content! But don’t get me wrong this build is beyond amazing.

Yes I do

It still bothers me that the part is first soaked in acetone and then sandblasted, all the heavy oils get sanded away by the sandblasting component anyway and the part is even more dusty after the sandblasting. The only oil I could imagine beeing left on the part is AFTER the sandblasting from the compressor that is powering the blasting nozzle... So it makes even more sense to soak them after the blasting to get oils and dust off them.

The process I use is exactly what the manufacturer recommends. Not going to go against that.

watch in 1.25 speed

Dan Tube no

Just perfect

Best 20 minutes of my day

Haha thanks dude!

Thanks Cameron! You are that mechanic that we need all

Thank you for watching!

Very nice!

Very nice video

19:43 missing float bowl screw :)

Great one as every one of them, i really like the look of that carby, it is a piece of art.

That turned out awesome! Never seen that done before.

Thanks man!

Perfect job

Cant wait to see the bike

Is that the mikuni tmx 38?

Hi bro what sort of tape are u using


Can you coat the pipe ?

let us know how this badboy wears. I think it looks great at the moment.

I found out about the TMX carburetor is it's very lazy on the start mine came on a 2001 CR250 so I did a lot of research. In the TMX carb it comes with a number 9 dump tube if you go to a number 7 dump tube it makes the bike even more Snappy. Then I also bought a 2007 needle for the newer style Mikuni and it was like fuel injection on the bike just giving you guys a heads up. That way you don't have to go bye a new carburetor

nice cam

Way shinier then they was.

I have a question about a bike I am trying to get running. It is a 81 suzuki gs550 t. It has 4 carbs. I have tried just about everything to get it running. First I cleaned the carbs and it would idle but die. Then I fixed the pilot screws and it wouldn't start without starting fluid and it wont stay running. I dont know what's wrong and I dont want to have to take it to a shop. Any ideas?

benson420710 I usually start it using a battery starter so I dont kill the battery. How difficult is it to check valves?

MilesGC1999 check the valves and battery voltage

Great video . I can't wait for a step by step on jetting a carb .

Thanks! Good idea

sorry to ask. 1. so if the air mixture screw is half or one turn to open from close position, the pilot jet need to be bigger right ? 2. if it otherwise, the pilot jet need to be smaller right ?. if you can help me it will be great. im bit confuse in jetting the carb.

+Cameron Niemela yess

Yes, with two stroke carbs the pilot will need to be bigger if the screw is less than a turn out.

When will the whole bike be done?

Just a little touch to make the screws look a little better would be painting the screw heads gloss black. Love the vids keep it up

What kind of buffing compound leaves a black residue/color on your wheel? At my school we use just a handheld 6 inch (i believe) buffer with the 3m trizact compounds and that doesnt leave anything on the pads. Thats strange.

beautiful job

It's all about the details I know your pain with perfectionism my friend. Great Job I feel better too. Have you tried any of the 30 other colors of Cerakote?

Haha, it's a struggle. Yeah, I've used 4 of the colors so far.

You should sell that carb and get a kehin pwk airstriker 38mm. I had the old tmx carb on my 02 cr250 and bought the kehin, best thing I’ve done for the bike. Amazing difference in bottom and mid range

That mikuni looks sick bro! But you should sell it and get a keihen owl 38 mm.. all good though. That carb is just nearly impossible to keep dialed under elevation, and temp changes. Makes better over rev though dialed. Did you do any cylinder work? The CRs from this era like .30milled off the base, and head squish corrected if you run pump gas to avoid pinging. Dude that CR is going to seriously look sick! I’m jealous a little.. lol I think I might get my calipers and masters done by the company you recommended. Thanks again bro! That CR is going to be magazine worthy for sure! Peace bro

This bike is going to look amazing with all these swanky pimped out parts :)

Yeah I sure hope so!

That’s funny I actually have a carb cleaning I need to do soon.

When are u going to put the bike together

Nice video

Hey man, can you not just put the oven rack in backwards so you don't have to tip it up with the part on it? In some ovens, you can. :-)

Nope this one wont go in backwards

Love the carb and creativity man! Looks dope

Thanks dude!

Mikune Not Good, Put Keihin Pwk The Best...

Are you still tearing bikes down in the back round for revive moto during this build Cam?

You should of coated the nut where you can access the main jet at

Definitely turned out awesome. Im hooked and want to try ceracote myself

Awesome project! I do recommend swapping out the mikuni carb though as the pwk carb makes the bike run so much more crisp.

Samuel Clemens dynojet has a good kit for mikuni carbs, my dr200 gained almost 10hp with the stock pipe at stage 3

sangat bagus ilmu yang bermanfaat. (indonesia )

Amazing looking carb! If you had to pick between doing powdercoat and cerakote, which is better to get into? Is one cheaper than the other?

Thanks man! I personally prefer Cerakote, but it is more expensive.

Jourdon Gulick he’s made a video on that topic

Man I I thought I was a detail oriented nut after watching your build I realized I'm not that bad

I wish i had all the tools like you do bro, makes things so easy

Never have I ever seen such a good looking carburetor, It was very nice that at the same time as you out it back together you introduced the way it works and i finally realized whats wrong with my carburetor and now my Aerox is running smooth as silk thank you for the tip!. Btw very nice video so clean and fun to look at high quality stuff.

damn that looks good!

Thanks Levi!



Keep doing this kind of content sir

Jeebus! You do nice work!

Nice looking Carburetor. Can you power coat a Weber DCEO Carburetor?

Hey that is a Mikuni tmx38 that was only on like 2 years of cr250s! It was on my 2002 KTM 125 for some reason lol. Had to do a lot of readers to figure out what it was.

How well does the coating hold up against fuel?

So far it's held up great on other projects

Have you tried to buffing Cerakote

Cameron Niemela it may give it a brushed look

I haven't yet

Thanks! Yes, it is possible to powdercoat a carburetor

I recently did that to my carb too, just with paper towels and AUTOSOL. Almost same result

that's badass! nicely done!

Best Carburetor porn I've seen lately. You attention to detail and choice of coating colors are spot on! Thanks for the inspiration for my 2004 Bandit 1200S...sweet!

Thanks Matt!

Looks a lot like a magnesium bodied carb. Very worksy man!

Looks fantastic!

Over 50k views in a month. Your the man broski.

That grease gun is so satisfying



Why you polish it when you sandblast it in the second step?

Make sure you put the air fuel mixture screw (the one with the spring) in right it requires a certain amount of turns on a 400ex its 2 and a half turns

cerakote some dirt bike rims and see how strong the paint in compared to powder coat and anodize

Cool idea and nice job! Wont be the 4 screews on the sides rusty after a while? Because you sandblasted those and they possibly will loose their coatings, won't they?

hey.. sorry for posting on an old video. not sure if this will catch your attention or not. I have reading about ceramic coated piston for a while an I was wondering if cerakote is an alternative solution for professional piston ceramic coating. since you have the experience on using cerakote, what is the maximum temperature that cerakote can withstand and do you think it can be used for this particular application? thank you.

nice job

I like your videos cuz you don't go on about crap and have annoying music

I smashed it....nice lookin Mikuni ya done built. CAN'T WAIT TO SEE THIS BEAST COME TOGETHER, probably the cleanest 03 on the planet...I'll buy it for $800.

Good work my friend


What is that tape called you masked off with?

I hate carbs....

Absolute perfection


hawe a problem with index finger from left hand ? you don't use too much

hey Cameron, can you not remove the scratches with drexel?

I'm satisfied by your work! Keep up the good work man. Keep your hands busy. Lazy hands, are the devil's playground hahaha

jan hebat

I’m serious, you’ve got the nicest shit that most of us blue collared people don’t

What do u do for a living

that burnt bronze looks amazing.

your nit a fan of polished aluminum??? really?? youre a douche!!!

Have you ever tried soda blasting (baking soda as a media)? It works well and you can wash the part with water without having to worry about the sand getting into your engine

That carb looks awesome!

wanna see you do a am6 motor rebuild and tuning!

Bolts aren't look as shine as other parts. And it's spoil the picture.

Thing is a work of art

This video shows again how beautiful technology, attention to detail and craftsmanship is.

You should do a sample piece with the coating and do a scratch resistance test.

Looks amazing !! Full polished would have looked just as good. But this carb is to die for

u should make some d v d on bike repair .it would help d rest of us thanks for showing us how2 do it.

To do the edges use the last soft wheel light not to aggressive just lightly you’ll have great results try it

An unusual blend of rookie and expert work shown in a slick and professional presentation with a great musical backing score, you got me, I'm subscribing.

Cameron your vidos are the best you inspire myself and many others and just wanted to say thank you for the videos super helpful

Macho ALFA!!! :D

Beautiful work

perfect/ Watching you.

Do you know Niemela or Niemelä is Finnish last name

do you ever use a torque wrench? how important is it to use one?

Congratulations on work.

Everything is looking good man! You seem to have enough patience to make every detail exactly the way you want it. I'm usually to impatient to spend this much time on one part! Also man it would be hard for me to ride a dirt bike that's going to be this refined as hard and through as much crap as I other bikes.

*Buys electron *

Wow man good job. My son and I enjoyed all your videos. Be safe.

You do amazing work dude, i learn so much from your videos. you gave me a new interest in detailing engine parts between cerakote, powder coating, and polishing. Definitely something i want to get into, stay positive brother wish you the best.

You're an artist!!

What paint did you use?

You know what would make a sick vid bro? If you made a vid on the explanation between the meaning of rich/lean and how to change them.

Incredible Work Cameron. Subscribed

The carburetor appears to be zinc, not aluminum. To make the body shine like chrome, you degrease in an ultrasonic cleaner, then zinc plate using a brightener in the zinc bath.
