ive got a 00 busa. mods are small airbox mod, k&n filter, pcII, clutch mod and cushion kit, ram air scoops, and pair removed. i had an akro evo full exhaust with akro map before and the bike only backfired when i was in the 9k rpm ranged and snapped the throttle shut. even then it would only backfire once or twice in a row. i have now since changed to the brock gen3 pipe and BDE-014-G3 map and im getting backfire like crazy even when shutting the throttle at low rpm's. like around 5k and even when closing the throttle slowly. if i do it a 9 or 10k rpms it backfires about 6-8 times in a row. any help is appreciated. it doesnt feel like im loosing any power but its annoying as hell. dont know if this helps but it has a very poor throttle response from a 1st gear roll on at about 5-7 mph. id expect it to break the tire loose like crazy but it stumbles at first and then picks up like its suppose to. i have adjusted the tps sensor...could the exhaust bolts be loose causing it to suck air (i reused exhaust gaskets), or could the throttle bodies be out of sync? its got 18000 miles and they've never been synced.
