Well I havent posted in awhile so here is my on going problem. The raider does not like to go over 55 mph and has no power past 2900 RPM. So far i have put the following new parts on. New dizzy, cap, rotor, wires, mech fuel pump, NGK plugs (gapped them), new 32/36 weber carb, new pacesetter header, checked timing (good), compression: #1=135,#2=150, #3=135, #4=155. No vauum leaks (used carb cleaner can to test), adjusted carb per weber instructions, removed jet valve adjusters to disable the jet valves, new coil, checked voltage to the coil (good). Dont know where to go from here? The fastest this thing will go on a slight downhill is 60 mph floored. I am wondering if i have a head problem or what? Any more advice would be appreciated. <img src="/forums/images/graemlins/patriot.gif" alt="" />
