I have the wierdest bog and its really starting to frustrate me. whenever i hit a bump or go off a jump my bike bogs and tries to die. For example yesterday i went riding and decided to launch off the top of this hillclimb and my bike bogged midair and when i hit the ground the bike was already dead and well i racked myself because of the sudden loss of momentum. I know this isnt normal or safe. what do you guys think i should do? the guys at the bike shop have mixed feelings...one guy told me the quick shot would help out but the other guy said that the quickshot wouldnt work and i should change my jetting. I dont want to spend the money on the quickshot if that isnt going to solve this problem. does anyone else have this problem and what did you do to fix it? thanks

Sounds like a float level issue.
