Hello guys I'm back. I just picked up a leftover (new) 08 and want a little more top end. On my previous 700 Rhino I installed a machined sheave and Dynatek cdi and was very pleased. A buddy just traded in his rhino and sold me his dragon fire cdi for $100 but I need to know what is a better route to go for the drive system mod: Coop45's mods or WV Hotrods machined sheave with greasless guts? Anyone have experiance with both?
