My 2007 roadglide has issues with starting. Sometomes it starts fine 30%-40%, some times it grinds but starts 30% - 40%, othertimes there is a knarley nashing and it stops turning over and does not start. The bike is 100 % stock with 42K miles. There was a service bulletin on this stating to look for signs of arking at ground points. I have pulled the starter, cleaned all mating surfaces to inner primary and ground cables with grinder / scotch pad. no help. pulled starter 2nd time and opened primary to inspect gears all look good. This bike NEVER started nice/ smooth like any of my other bikes.You can feel it engage in the seat of your pants.
