I just bought a 09 summit 154 with the Bikeman 880 kit, has the y pipe, pipe and can, bikeman clutching and the timbersled intake. I ride at about 9,000 to 12,000 feet. 1st ride it was OK but not pulling past 7,800. Clickers were on # 2, went up to 3 and then # 4 now it will pull close to 8,100 and Im wondering if I should run it higher? have not looked at jetting but the plugs look great. I'm running about 25-30% sunoco 110 leaded and 91 pump gas. it pulls pretty good, faster than my stock 06 but not scary fast. I run it WOT a lot. any recommendations would be great!!
