if i do no handers or something where i cant give the bike gas it falls right down from a wheelie...i turn my idle to 4 or 5 k and still as soon as i stop choppin the throttle the idle wont keep the bike up...is this how a 636 idle is because i just got this bike but from riding other peoples 636 i never felt that weak idle until i got mine...has any one ever had this problem or felt this way after goin to a 636 compared to a f4i or such?

 

strange. check to see it your brake is sticking.

clean air helps a little too. but im going with a sticky brake.

my 636 idles sweet..

 

air filter, plugs, normal wear and tear **** I'd try to fix first
