Winter Project

Oh Christmas Tree, Oh Christmas Tree.........!

This winter, I want to tear down my bike. I want to install the 03 YZ450 exhaust cam, a James Dean jet kit, and get the head ported and polished. Does anyone have any suggestions on where to send the head for the port/polish job? How much of a difference will it make? Will the difference be mainly on top end pull, or clear thru the rpm range? Thanks guys!

Go to www.mototuneusa.com his ideas about porting make lots of sense. :)
