I have a 2014 FZ09 with a full M4 exhaust. As far as I know it hasn't had the ecu reflashed and I do not have a powercommander. At about 7k rpm the bike cuts out, sort of like hitting rev limiter. The power curve is good and then it just drops on its face, it was so bad I thought it only reved to 7k and the rest of the gauge RPMs were for show. I stayed hard on the throttle one pull this evening and it powered through the rough stage 6800ish to 7300ish and once it hit 8k RPM it pulled like hell as it should. Has anyone else had this issue?
