I've been facing a fuel supply problem on my 2002 CBR 954 since a very long time. I have tried getting around it, but the solution all these times has been only temporary.
Fuel supply seems to cut off on rapid opening up of the throttle between 1800 - 2800 RPM odd. I can sometimes get away if I control the throttle very very gradually. It seems find until the bike is warmed up. At idle the bike sounds like parallel twin due to the distortion in fuel supply.
I have in the past replaced the ignition coils, had the injectors cleaned, but the perfect state seemed only temporary. I've even tried switching maps on the PC but that didnt make any difference whatsoever.
I have had the bike since 3 years and it ran rather well till a year ago since when I've been having this issue.
I am running a PC3
and an Arata full system on this bike, but it doesnt seem connected to either since I have been having this problem before I installed either of them. Infact I've had the PC ever since I bought the bike.
I had gone dry on fuel a couple of times a year ago due to the warning light not coming on, and I'm forced to think that may have caused the fuel filter to get clogged with whatever impure paticles there could have been on the bottom of the tank.
Am I thinking on the right track? Any other areas to look at?
