Common Wear Items:
Clutch plates, primary chain tensioner (especially on earlier Twin Cam models, though improved by 2013), fork seals, and wheel bearings are typical wear items.
Electrical Gremlins:
While the Twin Cam 103 is robust, electrical connections and grounds can sometimes be a source of intermittent issues, particularly with age and exposure. The manual's detailed wiring diagrams are crucial here.
Crankcase Sensors:
Issues with crankshaft position sensors or camshaft position sensors can lead to starting problems or poor running conditions.
Valve Adjustments:
Twin Cam engines typically require periodic valve lash adjustments. The manual provides precise procedures and specifications.
