Hi guys, first post... I've been searching and reading like crazy on here, but need a little clarification. A lot of info is geared towards the 06's, which I thought had slightly revised engines. My 2005 YZ450 seems a bit lean to me. I have a GYTR pilot screw set to 4 turns out. The ideal cold start for me is to pull the choke, and give the AP 4 squirts, then kick. Fires right up. Also, the 0%-25% TP range is really abrupt. I've seen a 45 pilot and 165 main recommended for sea level, hot, humid weather, but according to the ronayers fiche, those are the standard parts. What should I do?
