what main jet is in there now?

are you running the stock lid, or not one at all, or a vented one

what do you mean by not running right, where are you experiencing problems,

0 - 1/4 1/4 - 1-2 or 1/2 - to full throttle

I run a 130 main jet and stock needle position and mine runs good with this jet.

I have a 126 in it now with the air box lid on and no vents. It sounds like it is heavily modified because it kinda pops and sputters when u hold the throtle at maybe a 1/4 but when u get in it , it takes off without hesitation and runs good. After I get my axle bearings back in I can try the 130 out. That axle nut is giving me a fit.........
