My compensator nut came loose and over the long period of time this was happening the engine at idle got rougher and the whole front end (the fairing seemed to ampify the vibration) would be shaking. This is my first harley (bought it used with over 60K miles on it)and I didn't know what sounds were normal for a high milage harley. Dealer said the noise it was making was a loose primary chain. They adjusted the chain and it was somewhat better. The following spring it was getting worse and when I decided to check the primary chain adjustment myself. I found a cracked tentioner shoe, a worn primary chain, a very loose compensator nut and an alternator rotor that was severaly worn from rockin on the crankshaft. Normally all these parts plus the cluthpack/flywheel rotate together as a single unit to dampen the pulsing of the engine, but with all the slack between the related parts the engine can develope some serious vibrations and a very rough idle.
