Here is the problem.... When I jump my bike, in mid air, it will stall (sometimes). Now these aren't any large jumps either. Just some small doubles and a short tabletop. Everytime I hit the air, it will die. My son was riding it the other day and complained of it stalling while corning on our berm (left turn). That one only happens rarely though. Any ideas?? I have yet to mess with the fuel screw (just not enough hours in the day). Is that where I should be looking??
