whats up fellas , so check this out I had a bone stock 03 rm250 . I re-sleeved it , put a wiseco piston in it , vforce reeds , pro circuit ex chamber and a phat head, now my question is I think stock the main jet is at 172 which I think is too high now cause it smokes a little more then I want it too and drools out the pipe. Should I go lower then a 170 main or possibly need to go way lower?? Pwk38 mm stock carb
