Ok.. just bought an XR650 all supermotard'd (is that a word??) out. When I reach the balance point during a wheelie the bike starts stuttering and running rough like it's trying to die. The further back I go the worse it gets.....and if you go back into a coaster as soon as the clutch is pulled in it dies and is hard to start back up.

Oh.. it also tries to die during stoppies too...

Anyone know what I need to try with the carb? floats, jets?

 

Sounds like the float is either too high or too low My .02$

 

yeah man sounds like the float needs to be adjusted...
