Well my buddy just bought a 2005 RC51 yesterday, It has all of 4,500 miles on it, only Mods are two bros Slip-on pipes, and a PC III.....We picked up the bike around noon, drove around all day/night, finally about midnight we were in the city with about 12 bikes and it stalled out at a light... The key was on, the lights work, its getting power, even when you go to hit the start button it sounds like any bike starter and sounds like its going to fire up but it doesnt...It almost seems like a fuel issue like everything else is in place but its not getting fuel...What do you guys think? I just dont get why when we picked it up it was fine, and we rode all day/night, i was thinking maybe something with the PC III but then it would have been like that all day....idk im kinda at a loss, Ive only been firmiliar with RC51's from what ive read/heard and the 8+ hours or so my buddy has had the bike....you guys would know alot better then I would hence why I am here!....Any info is appriciate guys, just lookin for a little guidance in the right direction.....thanks.

Sounds silly, but make sure the engine stop is "ON". The RC will turn over without fuel pump with the engine stop off. WEIRD, my '00 929 will not turn over AT ALL with the engine stop off. I experienced this when I first got the bike and was confused. Make sure the switch is on, sidestand up, and KEY ON, you should hear the fuel pump cycle, then, it should start. Sorry for being so obvious, but this tripped me up DAY1 with my bike.

yea first thing i checked, the engine stop is ON....kickstand up, key ON, and the fuel pump actually kicks on, i can hear it like everytime you turn the bike on, but once i go to hit the start button, it just turns over but doesnt fire up...im at a total loss

Mike, I had a similar experience w/ mine and it was the plugs. I pulled both, dried them off and it fired right up. The RCs are notoriously finicky on plug, gaps, etc. Just another suggestion. Let us know what you find.

Don't have a reply but desperately need to know how things worked out! Was at the track on tuesday. Did two sessions with no trouble (and no crashes) and the end of the third session it started bogging and died. It started and ran for short distances two more times now will not start despite the starter cranking normally.

RC trouble

Replaced the plugs as many have suggested. They looked fine and bike still did not start. Took out the only non-Honda part responsible for it running, the PCII. Bike started, has run well in street and track day capacity. Still would like to have a PC but not sure I'd know the difference anyway. Thoughts on tires anyone. Pilot rear has a slow leak. Thinking about 2CT or Bridgestones (always use Michelin but Bridgestones 002 a little cheaper.

When the power commander is connected, it becomes a key system component.
It stands between the ECU and the injectors.
If it dies or has a problem, it can affect the whole fuel delivery path.
It's not the first time I've heard of this occuring, although it doesn't occur a lot.
They are pretty reliable.
But it's always good to simplify a problem, and disconnecting the power commander unit was good step.

alright guys i got my bike about a week ago didnt start but took it to the shop and they said that where the previous owner fueled up the gas had water in it so we flushed the fuel system and cleaned the tank started right up/// smell the gas if it has water it doesent smell as strong, also to test the gas is to spill a little and if it bubbles up it has water ...... let me know what happens..
