while riding my 2000 Ultra the oil light went on off on off. I replaced the senor but it happened again. replace the syn. oil,new filter(3100 miles on old oil) and the light is off and the pressure is @ 30lbs @3000 rpms. Bike has 68000 miles. Now the bike is running ruff spitting back through the exhaust and the air intake with the check engine light on off on . The oil light remained off.
