Bike is running, started first crank, no oil leaks so far. When I was doing the oil sump, I took a look a the cylinder walls and they still show crosshatched marks.
Still waiting for the head protectors from powder coating. I was able to go slowly for a short ride, and get the oil up to temperature.
A couple of reflections for anybody attempting to do this at home:
Patience, patience, patience.
Italian hardware does not age gracefully, this is something I've also suffered with my Aprilia, you don't want to round any nut of bolt head.
Have good quality Allen keys ready, and I mean good quality, it will save you a lot of time and grief.
Go over the instructions here in the forum. Print them and have them handy if that suits you. When in doubt, stop and ask questions, there is no such thing as a dumb question.
Make sure you have all dowel pins in place, for the heads and for the cam carriers.
Did I say Patience? This is supposed to be fun, take your time.
Finally big thank you to Pete and all the people on the forum, that with their posts, helped me through this process.
