I've heard many people are running the stock gearing combo. I guess it depends on where you ride.

I run 99.9% dunes on stock gearing but with the DG pipe being more of a hi rpm pipe, I've thought about dropping a tooth in the rear, just have done it yet, also I would like to go to a ESR pipe, just haven't done either.


Once you get your parts, go out and ride it. jet it properly and you'll know if you need to change anything.
