i have a 2004 yfz450. It starts great and runs really good, but it seems to hit the rev limiter too soon in my opinion. It accelerates really good, but if I really get on it, it cuts out like it's hitting the limiter. Can the limiter be adjusted? Could it be an electrical problem? No cam mod, all stock. Any other possible problems that could cause this?

Thanks

are you sure its the rev limiter and not your jetting? If it is the rev limiter......put a tach on it to make sure its hitting at the right rpm.......These things do have a ton of power and you can hit the limiter fairly quick........they do make high rev boxes too!

The YFZ will seem like it will hit the limiter soon but it just revs very fast. If your clutch is slipping it will seem really bad too.
