Hi, my 2014 ultra lx is not supercharge, are not reaching full potential with full throttle.
The ski are not running over 30 mph, I just installed a new jet pump, new impeller, and spark plug, the engine has 140psi, the gas pump has 45psi. The engine are running 100% when you run with the ski the acceleration reach 8000rpm but after the ski reach 25mph the rpm drops to 6000rpm. What that possibly could be?
