[QUOTE="Rich Rohrich, post: 1458908, member: 16241"] Your bike doesn't have a rev limiter other than the common sense that a rider should have. If you over-rev your bike the valves can have trouble following the cam profile. This is condition called valve float. As the valve springs wear this happens at lower and lower rpm. Valve float can make a lot of noise in the engine, and is really hard on parts. It could even cause a valve to hit the piston (usually the exhaust valve) if you get too carried away over-revving it.
