I just recently put the power inc end dump pipes on my sxr 700 and I have the heel clicker 40-10 weights installed. I am running the recommended 3.8 in the shoulder, 3.3 in the center and 3.3 in the tip with the red spring and am running around 8400 RPM but fall to 8200 after a couple hundred feet. I was wondering if you have any suggestions on what weight to run and what secondary helix and spring to run. I am currently running a straight 43 degree helix i think. I do have a hauck g 49 41 degree helix to try. Any suggestions would be helpful. Thank you.
