bansheeryder_69 Posted March 12, 2006 Report Posted March 12, 2006 as long as your not messing with the fuel/air/exhaust/or intake you shouldn't have to mess with the jetting. When you mill the head all it does is bump the compression up which is just how the fuel/air is combusted within the cylinder so you should be fine Quote
