OK, I've got a 2002 KDX220 with an FMF Gnarly pipe and Turbine CoreII silencer. The thing really hauls once your on the pipe which by the way is about half rev'd out. The problem and my question is what is the best mod to get some throttle responce(snap) in first gear low rev situations? I'm looking at getting the head milled by RB Designs and then gearing down some. I ride tight woods and getting over obstacles is a bear with the KDX. Any other suggestions, comments?
