I just replaced the throttle and idle cables on my bike as they somehow ended up cracked and bent after a service at my dealer 
I think I have the throttle cable adjusted properly, but didn't adjust the idle at all.
Seems that the throttle handle turns smooth and returns to idle quickly so I left the idle alone. Maybe if the throttle is adjusted right you don't even have to mess with idle?
Sometimes when I start my bike now I smell gas more than I thought before. I did put in a new air filter though.
Anyway, if someone has any thoughts, I would appreciate them.
