    GP800 compression boost?

    Anybody ever figure out how much to mill off to safely bump up compression on the GP800. Also will it give me any more power/RPM up top. Just looking for some cheap easy power for an old ski.

    i dont know how much they mill off. i think its like for every .10 its like 10psi....or something like that...Im not sure about rpm but it will increase your low end power. As for staying pump gas safe it doesnt help top end unless its like extreme race gas compression.
