i had my bike jetted and eversince then when i stop quick and hold the clutch in my bike dies. some times when i start to shift from reverse to the drive gears it dies and i have to rev it right when i start it to go. some times it wont idle at all. i dont know what to do

 

any mods? elevation? temperatue??

 

First i'd try turning up the idle a little. If it's still not right, the idle mix probably needs richened up a little. For that you can just turn the fuel screw out a half-turn at a time until it starts idling right.
