Was running at Barber Motorsports Park last month, bike was doing great, 3rd session of the day, went through turn 8 and lost power, managed to nurse it back to the pits. Initially she would fire up, and I could feed her some gas, let off the throttle and she would go dead. Eventually she just would not start, turns over pops and spits but that is about it. Seems like the timing is off, replaced the crank sensor, and swapped back to the stock ECM, still doing the same thing. Any ideas would be appreciated.

Off the top of my head, have you checked the fuel pressure?

Voltage okay?

Aside from the simple stuff, have you checked the sump screen for pieces of cam chain guides, or other significant debris?

What all have you checked so far?

TPS?

IAC?

New fuel pump, screen clean, will have to check TPS and IAC. Thanks

Always a good idea to verify all the ground points when troubleshooting anything as dependent on stable voltage and electronics as these bikes are.

Have you checked for trouble codes?
