Need help!!!! Did a full service on my 2003 sportster and ran it for about 1 hr and it ran great. On my final run was throttleing out at 6800 rpms then the engine started to throttle down to about 3500-4000 rpms and wont go higher. Engine seems to be running smooth not knocking or vibratiions. No alarms or beeps! Boat cranks up perfect and Idles nicely. Can Someone please help?
