How To Install And Tune A Mikuni 22 Carburetor

[@4legdfishman]

Very helpful and informative! I plan on building 2 predators for the grandson's go-cart build, and this carb along with a stage 1 kit should do the trick! Thanks for sharing!

[@GoPowerSports]

Glad it was helpful!

thankyou for showing the clip you pushed in with the spring couldn’t find that info anywhere

[@kylesyx8432]

I just installed a vm22 on my 212 !! 👍👍 I haven’t put any performance parts on my engine. However I’ve port/polish shaved head Recut valve s and of coarse reset valve clearance Just a header pipe homemade muffler She’ll fly around the neighborhood if you can keep the front wheel down! Lol I kept a 65 t on back and at about 5-6 grand I’m leaning over the handlebars lol ✌️

Sounds great!

[@bluestayslit]

I had the exact problem you described, thanks for the vid! It was the rod not properly seated in Carb! ❤

[@GoPowerSports]

Been there, done that. Glad this helped.

[@fusiongxge5105]

I have a tip for anyone struggling to get their engine running after changing carburetor or doing anything with the valve springs. If you try to start and it “pulls back” or stops coming out, your valve lash gapping is not correct and needs to be fixed. For a Honda clone 196 or predator 212 it is about 0.003”

[@GoPowerSports]

Good tip. Hope others take note.

[@commoncentsideas1215]

I have 212 predator with vm22 carburetor on go kart… it starts fine… but when i press the gas, it dies…. If i very slowly give it gas, i can get going… but again, once you press gas all the way… it dies… i heard i need to change the main jet… I didn’t have the bigger jet, so I drilled the main jet hole slightly bigger… didn’t make a difference… can’t figure it out.

Thank you for the information I just install a Mikuni 22 on my Coleman CT200u and having trouble with the idle.

[@scoc253]

should do a follow up vid with spark plug reading after tuning the carb if its rich or lean. how to compensate and adjust/tune again if what is the result.

[@Bulletman426]

I agree!!

[@kylesyx8432]

I know this was old news. But there’s a lot to say about learning the carb yourself. The vm is so simple. You basically have a high and a low Always point your bike towards a wall on the incase you screwed the throttle up. It comes set close enough for your bike to run. So set your idle screw first, I sit my bike on a cradle to free up my rear wheel. I gas the throttle- turn screw gas throttle turn screw and after 5 min of gassing the engine, your ready to ride 👍👍💕

[@maciej2695]

Best video for VM22 adjustment! Thank you.

[@stevenbutterfield9154]

Thanks for the video. What should I do with the carburetor when it cuts out at full throttle?

[@Princesslilly12]

It runs on main jet at WOT. Change main jet, probably larger. Look at spark plug to see if it's running lean or rich.

Got one of these few months back... Got it tuned after it was doing the run away bike thing.. i got one ride around my property, put it in the garage the next morning it didn't want to start i got it to run didn't get far til l was pushing it back to the garage.

[@TheBiliken]

Thank you! I just bought one of these from you all and plan to buy more. Is there a cover for the air filter as we go off-road or something you recommend? Thanks again for everything, long time customer.

[@GoPowerSports]

You could use the air filter cover that come with the stage 1 kits, and just zip tie. Other than that, we may use a UNI Air Filter Pod for added protection. But we currently do not sell a smaller filter cover.

[@Fatandslowbuthasthemostfun]

I used to use a plastic coffee can on my daughters Atv when it was muddy. Drill a couple holes and zip tie it to the carb

[@mikesbarn1858]

After installing a new carburetor I like to spray the contact points with break cleaner and listen for an rpm change. No change is good. Change is bad.

[@jeroldlafferty54]

That brake cleaner is hard on plastic and paint. If you're checking for vacuum leaks you may want to use a silicone spray. Very good point checking for possible vacuum leaks.

I have two pit bikes with lifan 125cc engines and genuine Mikuni VM22's. What size pilot and main jets would you recommend at sea level?

Just bought one. The wholes on the adapter don’t seem to line up with the holes on my block. Any ideas of what I’m missing. Also mine didn’t come with a gasket

[@Ghost88890REAL]

It's pretty cheap on amazon for the gasket, For the holes it might be a little off but it should be correct. Unless you meant the mounting holes which idk the answer.

Had problems with the Mikuni that came with my rebuilt XR200R motor, wherever the screws where it ran above 2000rpm choke worked as throttle no revs barely on throttle, so found one same as yours here said for XR200, had marks where it was set (idle 1.25t) kicked over ran a beaut straight away, been buzzing around the village on it tonight, just has a bubble in the fuel line issue cause it's modified with a CL360 tank and the fuel line is hooped down up over and down to the carb, atm has a fat clear fuel hose on, just need to let the air fizzle out 😂 it's like a soda 😂 then it runs great.....hoorah ✌🏻

[@JNC1973]

So I'm probably the only one here still using the stock appearing modified ruixxing carbs but I am getting ready to make the switch over to a slide carb. Right now I have the Go Power Sports Stage 3 .650 Race Carb on my Mini Bike. It will be my first time buying a slide carb. But I'm having a hard time trying to figure out if I should get a round slide or a flat slide? From what I've read people say the flat slide is superior in performance to the round slide but it's a pain in dee ash to get them tuned right. As a first timer am I better off getting the lesser performing round slide or are the flat slides not that difficult to tune? I got a modified 224 and was thing of getting a 28mm Mikuni Flat Slide. But would choose something else if it is going to be extremely difficult to get running right.

[@GoPowerSports]

Our 22mm Mikuni Style round carb is super easy to get up and running. Just slap it on and make sure the ports match up. But the flatslide 24 or 28 Mikuni is one of the best carbs to go with for performance. We have a jet kit. Take a few hours to test and play. It's fun! We can get you in ballpark to start off with. 866-846-5278 or [e-mail]

[@mattl7345]

How do I remove the stock long bolts from the manifold to install the new bolts to attach the carb?

[@grumpycat3436]

Screw on 2 nuts up against each other and back the inner one out while holding the outer one still using 2 wrenches. It will eventually lock up and you can unscrew the bolt just by unscrewing the inner nut. To get the nuts off hold the inner one still and unscrew the outer nut.

Will i have to go and buy my own fuel lines for the kit or does it come with them?

This kit will come with lines for venting but not for fuel intake.

I followed all your steps, got my bike running great, went to put my new air filter on and bike keeps dying. No dirt inside filter it’s bran new. Any idea why this keeps happening?

[@johnwick-ii6il]

If the motor die's as you are installing the aircleaner, you may have a bad seal on the main o=ring that seals the carb to the manifold. In many cases the seal will become off center when the carb is clocked level. If you cant remedy the failure issue, then take the carb and manifold off the motor...in one connected piece. Then look thru the manifold to see if the o-ring is showing anywhere. It should not be exposed in any areas. There isI also a small chance that a restrictive aircleaner will cause an already compromised o-ring to begin leaking. Good luck.

I watched your video, it's very good. One question there is a hose connection in front of the fuel inlet on the left side of the carb (choke side), what does that connect to?

It may be a vacuum line, not used on bikes and atv's

[@Deucealive75]

It's just a vent. Connect a hose to it and let it dangle down with the overflow hose that connects to the bottom of the bowl. Connecting a hose to it just helps keep dirt out of it.
