On another note, I checked and re-set my valve lash. There is an unexplained quandary surrounding this operation. In the Guzzi english language service manual, the lash clearances are given as .10mm exhaust, .05mm intake. On the other had, in the italian language manual they give the spec as much looser .20 exhaust, .10 intake. I set my valve to the loose italian specs and the motor made noticeably more noise. Tick tick tick. I went back and re-set to the tighter standards (with a loose drag on the feelers). The motor sounds much better but I'll have to check back in a thousand miles to make sure the gap hasnt closed up.
