I have an 09 M1000. I put a SLP y pipe, pipe and can on the sled with an Attitude control box. I dropped the weights to 77 g and it pulls 7600 RPM for the most part. My question is: Would putting a different helix and springs help me even more to get more hp to the track? My brother has an 09 dragon and i'm just barely beating him when with 200 more cc's I should be killing him with no problem. What setup should I switch to if any? (I ride at 8000-1000 ft and weigh 185).
