I use my 10 for drag racing. This past weekend it wouldn't go past 7K rpms with the clutch in. If you let the clutch out a little it would go past 7K, but then it was hard to control the rpms. It sounds as if it's hitting rev limiter at 7K. A couple people looked at the bike. We were able to duplicate the problem the first time, but the second time the bike went past 7K without any problems. The bike was up to temp each time. Anyone know what it might be?
