Usually the starter overrunning clutch is the first part to fail in a modern (post 1988) Big Twin. Unlike earlier Harley starters, modern ones have the starter motor, solenoid and overrunning clutch built into a single unit, just like a car's starter.
In fact, Harley's starters are the exact same ones used in many cars, like Toyota.
So how do you know if the starter clutch is failing or has failed? The starter motor turns but doesn't crank the bike's engine.
You can pay big bucks to your Harley dealer or buy the same starter clutch much cheaper and install it yourself. The starter isn't complicated at all.
Do a web search for any of these part numbers:
Toyota part #0283010010
WAI part #54-82401
NAPA Auto Parts #4-1071
Remove the starter and have it bench tested at your local auto parts store.

10 Psi is all that's required..the Harley engine needs oil Volume..not pressure..the lifters rquire 8-10 psi of oil pressure...Use a Synthetic oil..not the mineral .
Your solonoid needs replacing. Solenoid.
Bad earth or battery terminals need cleaning. Failing that the starter motor needs replacing.
if its a sportster evo and all you hear when pressing start button is a clicking from under the seat chances are the starter relay needs replacing, take off the seat, undo the retaining bolt, unplug the relay and take it to any auto electrical supplies and get it matched, (or you could go to your local hd dealer, but add a 0 to the price)
If the starter is whining while the engine is running at an idle you have a problem with the ignition switch or the starter solenoid is stuck. The starter should not be engaged while the engine is running unless you are holding the key over on the start position.
