Carb issue

[Johnpaulcurtis]

I have a Sikk MX 125 pitbike, and it is having issues when i crack into the throttle. When im riding it, and want to pull a wheelie, or throw a little rooster tail it just spits and spudders and cuts out. But when i take the air filter off it stops. Im guessings jets, but idk.. Can someone help me figure out what it is? I got a pic of what air filter im using.

First and foremost get rid of that junk filter and run a Uni filter.

Reckon that will probably solve your problem. If not some tweaking of the air/fuel screw may help.

If that all fails then yes it's jetting.

I almost bought one the other day. But why does it rev and not bog when i take the air filter competley off?

Because you are letting more air in. Uni filter will increase air flow.

Try giving the air/fuel misture screw a half turn out.

Just going to be a matter of playing around with it.

Okay. Ill grab one at the bike shop and for the heck lf it, get some jets.
I run a UNI filer on my race quad, and you can tell a big difference of air flow.
