Fuel issue with 2004 CBR600RR
Long time lurker here. You guys have helped me heaps in the past.
I know there are many posts about this already but none have helped.
I seem to be having a fuel issue with my bike which is a 2004 CBR600RR with 36xxx I'm on the clock.
If the throttle is fully open the bike losses power but if I back off it gains more power.
As per other threads, I have done numerous things to attempt to fix it. I have put new spark plugs in, I have had the injectors cleaned and most recently I installed a brand new OEM fuel pump assembly which cost a fortune at $643 in Australia but it hasn't helped at all. While the tank was off, I was able to check that there were no kinks in any of the fuel hoses.
I do have a slip on exhaust installed but this issue was happening pre installing the exhaust (but before I had tried doing anything to fix it).
Does anyone else have any other suggestions for what my issue my be? I have been putting off doing further track days until my bike is fixed and am really keen to get back out there.
Thanks in advance!
