    I'm working on a 1986 sportster 1100 with drag pipes as the only modifaction to the bike, what is the rule to start jetting at? Right now low speed seems fine but when I rev it it falls on its face, the high speed is a 175 right now, I went to the dealer today and asked what stock jetting on the bike is and he said 155. Any help thanks.
