Im still confused if I need to go leaner or richer. With the obeln needle #3 I am getting a studder when I get on it only in first and sometimes second gear as the rpms increase, but when I shift into 3rd,fourth and fifth it flies with no studder. I tried to see at what throttle position the studder was happening, from what I could tell maybe it was a quarter open or somewhere around there. Its hard to tell exactly. I tried clip 4 with smaller mains 162 and 160 and it ran worse, more studders. I tried clip two with a 168mj and it just seemed slower, studdered also. clip 3 by far feels most explosive. I put it back on clip 3 and tried a 40 pj and a 45pj. 45pj ran terrible and 40 seemed a little slow to rev. The pj screw was about 1 out on each. So I'm back to obeln #3, with stock settings and not sure were to go from here. I ride in Gaylord Michigan, I think Im around 1000ft with mods in signiture. From looking at older posts, Im just getting more confused. With the uncorked pipe and air lid removed you would think things would be leaned out, but when I went to clip 4 it jsut ran like hell. Also when I start my bike cold I can pull the choke in right away and it will run. Is that a sign of rich pj. Any help would be greatly appreciated.
