2004 FX HO problem to get to top speed and top RPM

Newb, not mechanically educated but did some research prior to post this thread.
My FXHO has 70 hours worked very good since day 1 till now and since 2 days I cannot go more than 8000 rpm and max speed at 38-40 mph. Used to get into the 54 mph.
I checked on the forum and will go through some basic checks: Will check and change this week the spark plugs. I checked the impeller though the inlet and there is no seaweed of sand. I could not check the impellers itself but will do it.
Engine is running fine as usual. I am not on L-mode (I locked it, unlocked it and get the 2 beep for the regular mode).
Is anybody had similar issues and fixed ?

Do all the basic checks. Compression etc and write back. Also check fuel pressure with a gauge. Replace the plugs first though. It wont be anything in the pump causing it to only rev to 8000. Possibly cam position sensor.
