Just picked up some of simons pipes and need to know the set up. I tried to call him today but his mail box was full. What rpm do the run at? what jetting I ride in upper wi, and some clutch help. Thnks
Run 47.5 pilots; 147.5 main jets & raise needles 1/2 right across. Clutch it to run at about 9k rpm.

I ran those pipes and mine seemed to run better at 9100-9150 on top end. I ran 150 mains and they were rich but i had a tempaflow, 147.5 should be right on the money. Really were good pipes when you get some heat into them.
