Bike only starts with WOT...then just stumbles.
----SOLVED---- Thanks 600RR Net!
Sorry for another 'wont start' thread... But, Honestly I have read many many 'wont start' threads on here, none with my problem.
Bike is a 03
I just finished reinstalling the engine after having the lower case off to be welded.
The bike starts if you crank it with the throttle pinned WOT. The engine slowly starts to fire and stumble till it finally will sustain rpm without the starter motor engauged. Continueing WOT results in the rpm getting to 1500 till it finally dies.
I have replaced wiring harness, ecu, remove pc3, changed map, jumped the bas. Charged the battery.
When pulling the lower case I had to remove/reinstall a timing chain guide, I am going to check cam timing in the morning... Does this sound like a cam timing issue?
While the PC3 was plugged in the LEDs on it went up and down with the throttle, so I believe the TPS is ok...
I have ohm checked the cam and crank angle sensors... they check out according to the Honda manual.
I have my was complete running 04 600rr sitting next to this one I am stealing parts off of to restore my late friends bike as a tribute. So logic would say I can make his run.
Thanks for your time and knowledge.
