Ok, so it's definitely speed related. Anyone know what the top rpm spec for a Grizzly is? Is it possible the clutch is slipping letting it wind too high in forward? I know it starts to crack up at about 7 grand which to me sounds awfully high for a four stroke. Personally, I can't see a need for much more than 5000RPM at any time. Anybody? Anyhew, if the rpm settings are normal, and if the limiter does kick in at 7000 on a normal day, then we have a slipping clutch....piece of cake. Too bad I won't be riding it at 85km/h (50mph) to test it.
Speed ain't my thang....
So, clutch maybe? thoughts, ideas?
