2001 F4i fuel/electric issue.
Ive done some searching on forums with many mixed cures but nothing thats definete. My first post here. Over the past 2 weeks my f4i with 29,500 miles has been having problems. Bike mods: micron exhaust chopped to roughly 4". No tune, dont believe valves have been done. Here are the symptoms.
All this happens above 165į+ on the cluster temp, the hotter it is worse the bike runs most of the time.
FI light comes on at random times, usually at engine brakeing or steady pace riding.
Stalling, unable to start again unless maybe bump start or turning it on and off a couple times. If im at speed when it stalls i can sometimes bump it on and keep going.
Rich exhaust smell
Unusual gas efficiency
Unsteady engine speeds when steady (if im steady at 5k for example, rpm stutters between 4800-5200 roughly without changing throttle positioning
A week ago i replaced the fuel pressure regulator, didnt fix the issue.
I have come to believe that it could be r/r, stator, fuel pump, battery, ground issue, could be anything. I dont have disposable funds to just fix everything on it so i am looking for help to narrow down possible issues, any questions or more details i need to provide dont hesitate to ask
