'04 144" Viper Mountain

My Detonation Sensor keeps coming on when I'm on the throttle hard (w.o)
Engine turning up to 8900 rpm's.Bought sled new as a non-current model.

What clutch set-up are you's running on these things. Right now it's all stock.
What weight rivet should I be adding. Spoke with dealer for heavier rivets in tips but he says 4.5 is heaviest and that's what is already in there?

Thanks.

If you are stock, I'm pretty sure +-8500 is what you should be pulling. Unless it shanged with the 04's. What fuel are you running and at what elevation. You might through a tank of premium through and see what that does. Look for Turks post as he seems to be one of the resident clutching gurus.

My friend order a viper mnt last year from a dealer here in MI. WE had a week trip planned for the u.p. and that sled had something flashing 50% of the time up there and no top end. Took it back to the dealer and told them to CLUTCH and JET it for MI!!!!! It was set up from the factory for something like 5000ft.
