Thumpergod,do a search on jetting & read on.Also you may want to check some of the signatures of the guys that are riding near your elevation.YZ needles seem to be the choice of most.I run an OBELN form YZ250F.I think you would probably want to try something a bit leaner at you elev.Maybe OBEKP Hope that helps :)

I posted my specs a few times and after reading numerous threads from 02, 426 owners, it seems more and more people are using the same settings.
