I just picked up the bike yesterday, and could use some suggestions for a baseline set up on jetting for 3-7000ft. The bike is completely stock, except I am installing a 52 rear sprocket, and an Power Pack from SLP(like a power now)in the carb. I am 180lbs with gear and am an intermediate rider. Suspention starting point would be nice as well. I ride tight trails (like 5 miles of hell), with some open sand washes, but mostly trails. Also, can I run Mobil1 20-40 oil in this bike, or will it make the clutch slip. I don't think Mobil1 has any friction modifiers in it, but am not sure. Thanks in advance.
