Re: 2004 Breva 750 Running rough on constant throttle
Mmmm so I though I had this worked out.
With the O2 sensor plugged back in after running for a while (feels like 5~7 min) the red EFI light would illuminate. Restart bike and light would stay on for a little while, but then go out. Not really running for long enough to see if it would come back on.
That was pretty consistent behavior with time being the only variable, but then I ride home today and the EFI light didn't come on at all. Mysterious self repairing electrics :lol:
Of course since none of this makes any difference to how she runs the "fix" (assuming the red EFI light is going to come back on) is to plug the black box from the PC-III back in but it's an intriguing puzzle
(I also wonder what this Service Bulletin - faulty illumination of EFI light had to say)
p.s. since reverting the PC-III to the zero map not only does she now run smoother but the bluing on the headers is disappearing. LHS header now has a big chrome strip up the middle where it use to be blue.
