Been undoing a lot of PO's hack jobs on my '71 CB350 (one example, someone cut off the throttle cable at the "y" and locked the CV carbs wide open with to air cleaners... took a rubber mallet/wood dowel to make them move...) and VM30's are on my bench for install after engine clean/paint. Great video. Yall at DCC have been a great help/parts source for me the last year. Got my Brass seat pan painted up and ready for install. Keep up the awesome work and great parts selection. Rock on.
Nice explanation of the model differences and nice to point out the accelerator pumps. My only observation of all "new" carbs is all the rough edges and surfaces on castings compared to good old 70's units. The visual finish/appeal needs some scrutiny from their QC folks, but if they run like a bear who really cares.
@@hoedemakerbart Exactly right. Even our Honda XR125 was made in China. And it shows. Our Makita power-tools has lost it's reliability because of Chinese made.
@@Deontjie it depends. I have a scooter repair shop. I order Chinese made keihin under license and they work great finish is good. But they also have the Chinese copy and that one is crap
I just ordered myself a mini bike mikuni carburetor from go power sports to replace my stock carburetor, I've been having issues with it so I bought a aftermarket replacement and I'm having similar issues with bad gaskets and what not I got tired of messing with it and said today is the day I upgrade to a mikuni. Hopefully I dont break it 😐
Did the VM 30 s for my Honda CM 400T rebuild. It starts ........awesome .....but with the choke levers down and and maybe for 3 or 4 min. it runs and quits. Now i gotta turn screws or something ?
I need help mines is on but idk what tubes go where I'm new to this I have pics showing what I need to do I just need someone to lmk know if Im doing this right lol
Even if you find the Mikuni name stamped on the carburetor, how can you tell which Mikuni carb you have, a MV36, or MV38? Also, is there a bigger Mikuni than a VN38? Thx
I have an 82 vf750 sabre. Is there a flat slide kit for me? Can you reccomend something if not? Cams are going to be .020 more on lift over stock and an additional 12* duration. Ported heads and a 4/1 open exhaust
Can you tell me if the tm carb is taller than a VM carb of same size. Specifically how they differ from bore center to the top of the slide tower. For my project there is very little room on top of the carb due to the exhaust pipe crossing over there. Currantly I have a 34mm mikuni and I would like to try a 36mm flat slide. Thank you bro.
Not to be super contrary, but you didn't actually explain how to identify the specific model of Mikuni carb on a bike. For example. I am specifically trying to figure out which Mikuni carb, or rather what series, is on the 90-94 Suzuki DR250s. Do you know by chance?
personally idk just cuz of the change in elevation. you should look at something like lectron carbs, or smart carb, they're a bit more expensive but pretty awesome, especially for something where you have huge elevation changes
I got a 4stroke thumper 125 cc is a vm22 or tm 24 gonna be better for my racing it’s had the vm22 from stock but I can swap manifold to stick the tm on the bike
Hi, great video I´ve been told that the TM and the RS series are exactly the same carburetors, with the only difference being that the TM is made for single use while the RS is made to fit with a total of four carburetors. Can you confirm if thats correct? Reason I´m asking is that one of my RS36 carburetors needs a new mixing body wich seems impossible to find as a spare part, and since I can´t find a place where I can buy just one RS36 carburetor I would have to pay 800-1000$ for a new set with four carburetors. But a well known motorcycle mechanic around here told me that the TM36 is the same carb and that it could be modified to fit with my three RS36´s, at a cost of about 300$. So I would just like someone with good knowledge of the Mikuni carbs to confirm that this is correct before I place my order on a new TM36 carb. Best regards Marcus
Hey James I'm Nick I have a old mikuni carburetor on my Polaris trail boss 250 I seen to can't find a part number to order a valve niddle and seat because it overflows like gas just when to 10c I have had it apart several times. do these carburetor have exchanging parts or would I have to have a specific part?
Are all the mikuni carbs have the same size choke spring nut ? the original one I had was plastic and broke when I was putting it back together. the one have is 11.8 mm and that is the threads that go into the carb. HELP anyone please and thanks.
So I'm rebuilding a 1985 Kawasaki Klt160 Atc and it has a Mikuni Carb but I have no idea what one it is, how do you tell what model and size of the carb?
I have a question. I'm using a 16mm mikuni carb, which is maybe a cpi scooter carburetor. I have cpi sx 50, yesterday i installed 75cc cylinder on it. It was brutally weak and slow before, and also now. I'm planning to buy a 21mm carb.
So I have a stomp z3 140 I bought a mikuni carb and a bucci manifold as a company said it all fits. The manifold and carb fit together but it won’t all fit onto the engine as it won’t allow the carb to then fit
Hi, I’m looking for carb for Kawasaki klt 160, the book says it takes VM22SS CARB with 110 and 22.5 jets. Any chance you could come up with one like it?
I've been spoiled being born in the era of EFI. Next bike I am planning on getting is a running a Mikuni carb. I'm nervous about going from EFI to carb. Is it a step backwards?
I have a genuine VM22 and have had it for 2 weeks and STILL unable to tune it right! HALPPPPP I know it's running rich but dont know what size jets I need!
Well you might need a new flange for it but it could probably be done. I have a polaris 400 and went from what I believe to be a VM30 to a VM34. Was tight fit on the flange and had to adapt fuel line from 1/4 to 5/16, but other than that have had 0 issues.
So yeah my beard is smaller but you don’t know carbs. The model I.d. Was very enlightening how ever. Throttle response was and still is why cv carbs are used. Your “average guy” wants to snap the throttle. You cannot snap a mechanical carb and be happy. You have to learn how to ride the slide. Cv is EZ. Twist at will and you will get your thrill. Mech=race. Cv=street. stop peddling knowledge you don’t have.
@@amadorrodriguez2718 needle n seat not properly working or float level incorrect, only way it can leak...also your fuel shutoff is probably not..allowing gas into your oil and washing down your cylinder wall..pretty important, any time I upgrade a carb i update the petcock
I know this is old post but any carbs off of a honda( keihn) 750 or even a gs 750 will work.you need to measure the bore(where the carb plugs into the carb boots) .any gs750 or 650 carbs (mikuni) should work,just gotta get the jets right, but i think if you took carbs off another 650 should jive probably.?hope this helps
I forgot to bump Keihin. Keihin is racing. Mikuni is civilian. Just the way it is. Love for both. Cleaning and tuning them has been 75% of my work for 18 years. Hash tag stop lying to the guys that end up in my shop for repairs. Wait is that too long? I normally only hash browns….
Mikuni carbs are the worst I've ever owned. I have had a 19 mm round slide and a 24mm flat slide and it didn't matter what jets sizes and how much we tried getting the air/fuel mixture screw adjusted for the right spot and you could get it adjusted to where you think it's going to run ok but go for a ride and it maybe ok but then next time I'd get on it and it be fucked up and not act right and no one had touched it. I trashed those carbs bought a Nibbi 24mm round slide and my motor purrs and screams when it's supposed to. So don't sit there pushing a company product that's a real piece of shit
