Read the ring gear, it tells you what the pinion is doing.
How about you, Mike? You are mechanically talented and know the ways of Guzzi.
After wasting a lot of time trying to read the pinion gear teeth as the two Guzzi manuals describe, I switched to the ring gear. Much easier to read.I am getting there now. I'll likely need to order some more shims, but I am close.Next up is figuring out how to measure the free play.This 8/35 should let me use 4th a bit more, and run about 4000 RPM on the highway, like I want.
Pretty warm. Am I just being overly cautious?
Yes. 12 miles isn't far enough to get it up to operating temp. It is a good start, you said smooth and no noise, leaks etc. Go do a 50 or 75 mile loop and you'll probably see 140 ish temps. Good enough to boil off the condensation and then change the oil when you get home and inspect for any weird stuff. Probably just fine. Paul B
They do run hotter than I thought they would, generally around 175F or more after about a half hour at road speed, depending on ambient temp, of course.
