[QUOTE="PALMER84ONE, post: 93005, member: 6"] Most pipe companies have a jetting/mixture scale that you can look at to determine whats best. You have to remember with a 2T bike it has to do with temperature/humidity (time of the year depending on where you live) in addition to altitude. My YZ250 both have different pipes and different jetting. But because they are both in So. Cal run the same Super pump gas at 32:1 Yamalub R2, and ride the same areas, we never mess with jetting them even between 1500-5500. Yah they run a little rich up there but thats better than lean. Another thing I was taught by the master of the 2T is, never let a 2T idle longer than a minute, minute and half when you walk away from the bike, thats when it is getting the least amount of lubrication in the crank,piston,head, etc... Long lasting motors if you run them on the richer side. [/QUOTE]
