open air box

  1. J

    Pleasee help..

    So I have a 1992 blaster and I’m new to two strokes. I just got the quad it has an open air box and a fmf silencer but stock pipe. I believe it has a 240 main jet and a 30 pilot jet. So the air screw is all the way in and it still seems lean. Not much smoke and I’m running 32:1. So do I go up on...
