Anybody know does my 01 warrior have a rev limiter on it? If it does I have never hit it. I have done a 366 big bore and cam and carb on mine and was racing my nephews 400 ex and after the race I noticed a noise in the engine. Tore it down and found the crank was getting bad. Put a new hotrods crank in yesterday and have it running like new again. I'm used to my kfx so I think I wound her up too much. What can these engines turn and be safe on the crank? Is there an aftermarket CDI that I can get that would have a limiter on it?
