1998 kawasaki bayou 220 Fuel Starved

[Hayden Pahnke]

Bought brand new petcock and carbetator, turned air fuel needle out 2 turns and machine still acts like its starving 4 fuel on top end. Any ideas?

How's your air filter? Did you buy a factory OEM carb or aftermarket and is it jetted? So on top end it's bogging down?

Air filter brand new. Aftermarket carb. Trying to replace stock Mikuni. Slide needle and brass mating tube wore out. I just installd carb. Backed out air fuel screw 2 turns and fired it up. It seems to lose power on top end. Like its hitting a rev limitter. Then backfires on way back down thru rpm's.???

Seems to be not getting enough gas past half throttle. Should i go up 1 size on main jet? Please help.

If its a factory replacement carburetor, you shouldn't have to change the jet size. Sounds like you have either an adjustment issue.

It idles great. It runs up to half throttle great, beyond that it wants to bogg down???

HA HA!!! Got it! Stock main jet is 110. Bought a 5$ 112.5 main jet, PROBLEM SOLVED. RUNS AWESOME.

Great news! Glad you figured it out. That's the problem with aftermarket sometimes.

Mine is doing the same thing.  Glad I stumbled here.  Where did you find the larger main jet?
