Little by little in past month speed has been slowing slightly while rpms have been slightly increasing. Now I seem to hear a slight rattle (as if not getting quite enough oil but there is no other indication of this) or miss (running a little rough). This does seem to smooth out after running for awhile though if there is an increase in actual performance it is not noticeable. Engine was running at 5500 rpm and 48mph. Now is running at 6000 rpm and 43 mph by gps.
Your thoughts, please.
