Guys I have a 04 Busa with 92k miles on it just got few months ago was stumbling during takeoff so I replaced plugs,fuel injectors and coils and it seemed to fix problem but now after month of riding it is now missing at a steady rpm, and taking off, its good when you are getting on it, but taking off and steady cruising it missfires, and also sometimes I heard small backfires when letting off the throttle, stumped ! thinking maybe in tank filter clogging up, bad coil I purchased even though I did a resistance test on them they look good, no load test on them though..... dont know, anyone with any ideas
