I'll keep reading the manual to ya if u hang on to the FTZ head till Wednesday for me. Haha! I wound up turning mine a little farther past 360' until I had the transition from mid range to top end that I wanted. Having that PV set right really makes a difference. I ride in the woods here in KY alot, and for an old two stroke, mine has a pretty smooth powerband. Mine currently has a mostly stock 87 motor with a 39mm PWK carb and an FMF fatty pipe. I'm running an airbox with lid removed, a 58 slow jet and a 160 main jet. The PV dial is about 45' past the 360'. It idles great, has good bottom end, with real strong mid, and screams on the top end. I love it!
