engine cutting out on track - need troubleshooing advice
Hi everyone. 2013 cbr600rr on the track I have very intermittent issue with engine cutting.
Happens about 3 times per track day at around 14,700rpm engine cuts off for about 0.1 seconds. Completely dies, and instantly goes back on. Obviously it's a bit scary because my front end gets loaded up instantly, and then a slight slip of the rear/clutch when engine kicks back on.
Another possibly related issue, every time I turn on the bike, and rev past 2000rpm for the first time only, I have the same hesitation engine cut. After that, I can free rev from idle no problem.
if I turn off bike, and turn it back on - again, once I rev up in the pits at around 2000rpm, engine cuts for 0.1 seconds and comes back on. It does that every time without fail.
Any idea of what I should troubleshoot? Crank position sensor? Rectifier? I already tried a new battery.
