02 RC51 - Dear God, Please Help Me!
First post, lots of problems! (apologies in advance for the long post)
I recently picked up an 02 RC51 WITH 9400 original miles for a song, but it was not running. After really getting into this beast, Ive come to the conclusion that its been sitting for some time (a few years I think). So far I've done basics like change the oil, new plugs, flush the hydraulic clutch sytem, and flush the coolant.
After getting the bike home I immediately noticed my fuel pump wasn't priming. I pulled the service manual and tested all the appropriate sensors and the checked the wiring to the pump. Decided the pump itself was bad (due to neglect) and ordered a new one. While I had the pump out, I cleaned up the surface rust and sealed the tank with POR-15. I installed the new pump and, hooray, it primes. I refilled the tank with new premium fuel and added in some Seafoam for good measure.
The bike will now start if I give it a little throttle, but not idle. I tried adjusting the Idle Control screw, but it doesnt seem to be making a difference (yes im using the choke as well). It is also running really rich with some white smoke coming out of the pipes, so I know its dumping to much fuel. I initally thought it was a TPS problem due to an FI light (all cleared now), but I checked the connection and it was just loose.
The odd thing I noticed (which brings me to where I'm at now with the bike) is that it will start and idle just fine when its cold, but it starts stalling out the warmer it gets. When taking it for a short test ride, it stays running under throttle (although it jumps and jerks a good bit), but stalls when coming to a stop.
I'm in the process (and dear god is it a process) of removing the airbox to get at the injectors. Ive come to the conclusion that I either have a stuck open injector or a bad fuel pressure regulator.
Any tips on testing FPR? Any help, support, advice you guys can give me on this would be awesome, because I feel like I'm taking 1 step forward and 2 steps back.
