I recently converted a 04' mod into a trail sled, it has a cudney head, factory twin pipes, reprogramed mpem, and kickass filters. I did not change any of the clutch settings or gearing when I did the conversion. The first time I took it out I noticed that the max rpm was 8000-7900 rpm on the tach, I wanted more rpm's because I have read that the twin pipes make more power at 8400 to 8600 rpm's. The stock pin weight was 18 grams and the clicker was set on #5. I adjusted the clicker to #6 and had a change of about 100 rpm, so I then I dropped the pin weight to 16.5 grams and clicker back to #5, but I am still not getting more than 8200. Should I take more weight out, 16.5 seems really low for a 800 mod especially with the clicker being set so high. The sled pulls really hard but I just hear everyone else running around 20 grams. I just want to make sure I am going in the right direction. Should I try the other angle in the team helix? Or should I go back to 18 grams and run it at 8000 rpms??????
