Struggling with 929 not running
- Hello all,
I have a 2000 929rr that I tracked successfully for years, then stored. I began to revive it as another street project and have recently hit an absolute wall and need help.
The bike will start, run great for 3 or 4 seconds, then begin to chug gently at first, then it will continue to get worse and worse until it seemingly drowns itself. I cannot ever get the rpm above 4000. Smells and looks from the exhaust to be running rich.
I have been attempting to trouble shoot and have already accomplished the following with No success...
-Changed all 4 plugs
-Changed all 4 coils
-When it does idle, all 4 downtubes reach equal temp, so I'm guess valves are operating properly
-New fuel pressure regulator (2 just in case)
-New fuel pump assembly including filter
-New oil change, filter, and coolant flush
-New Intake air temp sensor
-New fuel injectors
-Removed and cleaned fuel rail
-Disconnected and cleaned fuel rail and vaccuum lines
-New MAP sensor
-Disconnected PC III and tried to eliminate that as a source of trouble
The only thing I haven't done yet was replace the wax valve heated by coolant on the underside of the throttle bodies. Not sure if that could be stuck.
If you have ANY suggestions, I am obviously willing to spend the time and money to get the bike back to running properly. FYI, I pulled codes and nothing relevant seems to be appearing.
Thanks a million,
Ryan

Do you know anyone else with a 929 that you could borrow the ECU from for 6 minutes?
