OK, done 700 miles now, had an annoying vibration at 4000 rpm, real filling shaker. Fitted my H&B bars today and found the rear subframe bolts had loosened off during the shakedown i suppose, fitted the bars, tightened them all up and the vibration has gone! Glad really as it worried me slightly, considering what I have done...
So, I did a few miles today and still not happy with the engine. There is an annoying tappet noise from the r/h side. I did the tappets on the 500 service half expecting them to be loose but no. After the ride today I listened to it at idle and the noise is definately camshaft speed on the r/h/s.
Stripped the cam box off, and found the followers like this;
I'll get a couple of new ones, fit them and see how it goes. The cam is sound, plenty of oil there so it can only be these? Looks like they've lost their hardening?
Should have them by wednesday so I'll post up how it went!
