I have a 06 busa, 900mi on it. I have a stalling problem that occurs when coming off high revs. Also does this if i rev high and grab the clutch it just drops all the way and stalls. What i have done to the bike is, Yosh slipons, K&N air filter, cobra fi2000r. I fiddeled with the cobra but no matter what pot settings i have it at it still stalls. I also bumped up my idle from 800 to 1k rpms. Im thinking that when i let off the throttle the K&n is just sucking way to much air making this happen. I need some input from you guys or maybe its something else. any help would be much appreciated.
