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??????

thanks,
kep

I am not sure on the primary spring or helix setting. I was hoping to get a way with what was already installed, but it sounds like I may need a different primary spring. The question is do I need a higher finish rate or lower to fix this problem????? I do have a stock primary spring from a 04' 440 on hand but do not know if thats going in the right direction?????

thanks,
kep

lower finish rate on the helix will bring those rpm's up from my understanding.

Kep do you want to sell those 419 ramps you have in there. I have a set of 415 ramps that I would be willing to trade plus sum cash
