Bro, more info please. In what way is your bike not running right...Hard starting? Misses at low speed, will not idle Flutters while accelerating? Pings or seems to rev after you let off the throttle etc???

The easy answer is to pull off the mag cover, on the upper right side there is a mark in the cases, there are also 3 marks on the stator assembly, standard has the middle stator mark lining up with the single mark on the cases. the difficult way is to use a degree wheel and a dial indicator in the end you will be at the same place, the marks should line up, that is unless you've sheared a key, have you checked that?

So what is the popular setup to run for timing? And is it even adjustable?

Neither are stock, and both are great desert bikes.

yes it is adjustable.  I tend to run mine a little on the advanced position while I've read that Stewart seems to like it retarded for a little more over-rev.  As far as any reccomendation, I believe its all in preference.  I know two of my buddies that I race with had their bikes build identical, to a "T" and one thought his worked better advanced and the other retarded.  So I would say just play with it to see what you think feels best to you.

 From what I get, the adjustment is still between the marks. Center one is standard, the one counterclockwise retards the timing adding to top rpm's, and the next mark clockwise to the center is advancing it. Supposed to be better for tight technical tracks. Can't see needing more bottom end, so I went to the retard line. so I guess its true when people say that I'm retarded. :-P The book warns that damage will occur outside of those lines, so be careful testing.
