I have an 05 Busa with scorpion bolt ons and a recent new battery. mostly a stock bike though. I have been having this low idle problem where the bike does not run steady at idle, it surges always below 1000 rpm. if i rev the motor and let go of the throttle it will stop running, sometimes at a stoplight, sometimes in the garage. it has 6000 miles on the clock. i always use super unleaded. on occasion the bike will act like the battery is weak when starting and other times it fires right up. other than that it runs great. i thought that maybe the bolt on pipes and the heat here in arizona made the bike run different. i put on a PCIII usb today and the thing sounds better with some throttle but it still idles very low and quits when i rev it and let go. can anyone help?
