If its not sucking air somewhere then it sounds like the injectors are out of sync.....but remember these bikes are very cold-blooded and take some time to warm up. In addition the cam timing will be slightly off \ out of sync until the cylinders grow and the belts get tight ....Here is my situation. Im pretty new to working on motorcycles and especially new to working on my Sport classic. I bought my 2006 SC1000 last year with 1400 miles on it. Everything but the clutch plate was mint. My only reference to how a motorcycle should run was a 2005 R6 and a 2007cbr 600RR. Those bikes you could start and go. This bike needs to warm up for a while till I can drive it and it wont die at the first stop light (letting the engine warm only reduces the chances). When I start it up to let it warm, 50% of the time it will die in idle by the first 5 minutes. I should also state it idles unevenly. Meaning it will sound faster and louder then creep back down to a slow lug. I tried a FATDUC O2 munipulater without much help. It just felt a little smoother in my midrange. What should my next step be? Should I get my ECU re-flashed? Should I consider remapping my fuel system? Any advice is appreciated.
PS I dont know if this is worth mentioning but I removed the charcoal box without any change and I have a few holes drilled into my baffles for added sound.
