I bought a factory shop manual for my 2001 Yamaha Mountain Max, I would suggest the same for you. They give you much better specs than any aftermarket manual. Mine shows me clutching/jetting chart for different altitudes. I do know that the pto (belt side) *outside cylinder on the mountain max is jetted fatter than the mag or center cyl. My manual covers the mountain max, sx 700, and the touring machines and they all use a fatter (or leaner, the manual is around here somewhere) jet for the pto side. My plugs are real black. I read that the factory does that so you won't smoke the engine running it to lean, I have to come down a step or two, but I am going to wait till it has more miles on it (only got 200) good luck.
Winning/Reliability/Economy= choosing one eliminates all other possibilities.
