Yeah, the rev limiter is there for a reason. Something in the clutching is not right. Get the clutching right first. Make sure your belt is in good shape and not slipping causing the rpm's to run to high. You should be targeting 8600-8900 rpm on the engine. I changed a bunch of stuff on mine and have been slowly coming down to the right rpm. Mine doesn't hit the limiter until about 9250-9300 so you probably need to come down quite a bit.
