Wtf?

defector · 07-23-2009, 12:06 AM

I had to lift (yes, lift) my bike (CBR 929RR) into my truck and now there is literally raw fuel coming out of the pipe when I start it. The bike has been sitting since Saturday when it was lifted into the truck. No other leaks of any kind that I can see as of yet. What, if anything, should I be looking for in particular when I get the plastics off? Plugs will obviously be changed when I change the oil this weekend.

Lift as in vertical, or lift as in horizontal?

Vertical.

Its still FI so that shouldn't be anything crazy.

Have you started it since?

My guess would be that your CPU is freaking out, or you've blown a sensor.

The only thing you could look for, (visually) is loose/corroded connections.

Have you done any re-mapping?

Yes, and it runs like shyte. Sounds / smells like it is loading up with fuel. Badly.

My thoughts as well, but nothing jumping out at me currently.

No re-mapping, factory map.
I am sure it is something retardedly simple, I just haven't happened upon it yet. Or I am too simple to figure it out. I think I may pull the fuel rail and injectors to see if I have one leaking down in some strange coincidence.

fuel pressure regulator has failed. thats why its running poorly and has raw fuel coming out the pipe.

Good call. If the bladder has failed, the fuel could be leaking down a vacuum line.

That makes perfect sense. As I recall it was a fairly common problem on the Fireblade board as well. Thanks!
