I have an 02 Grizzly 660. I am running 28" Zillas and just did the 2mm shim to the primary.

Since putting it back together the belt sits about a 1/2” below the top of the sheaves. Is this normal? Top speed is around 40-45mph. I used to see 60mph+ with the stock tires.

I don’t feel an improvement in low end power from the shims.

Any help appreciated
