    Not enough to notice... Something that minute you will never notice.

    Just go up a tooth on the Counter-shaft sprocket - use a Banshee aftermarket one. Personally, I put 22" D Devels on mine and I was really happy with the results. I don't think you will notice much of a difference anyway.

    On my 85 Z I went with 22 inch turf tamers so I didn't lose any top speed or ground clearance.
