On Friday I rode up to the Guzzi Doc's place so we could do some final adjustments. The transmission had been giving me a hard time downshifting and by the time I got out of town on Friday all I had was 4th and 5th gear. That, plus the bike only wanting to idle on the left cylinder made for a shitty ride, but I managed to limp it the 25 miles or so up there.
It turned out that after a few rides the gearshift bias adjustment had gone out just enough so that the bike would not downshift to lower gears. The adjuster nut is on the back of the trans and more or less inaccessible, but we eventually got it adjusted and shifting through the gears fine.
We tore into the right side and found a cracked insulator for the carb to intake manifold, and re-cleaned out all the idle circuits, and got the carbs synced and idling perfectly.
Unfortunately as I was leaving I discovered we had destroyed the rear brake switch so I had to ride home in the dark with no brake light. Joe gave me a couple of original brake switches that could be rebuilt so I watched my ass on the ride home and eventually made it without issues.
Yesterday I wanted to ride, so I cut apart one of the brake switches, polished up the contacts, greased with dielectric grease and reassembled it with some gasket maker. Got it adjusted and now I have a rear brake switch again. (The front brake switch is integrated into the cable and absolutely sucks, it doesn't work unless the brake is barely useable so I'm dealing with that with the company it came from).
