Thanks! Me too. It's such a usable bike, I even took it to Germany for a weekend chasing my mates' Multistrada's through the twinties.
It has the vintage caferacer feeling, with modern performance and reliability.

It's for sale nonetheless.. I want to build another Guzzi next winter.

Took some time, but finally got my package from David Silver, with most importantly the re-engineered camchain tensoiner:

I love to see Moto Guzzis I hankered for a V50 - a girl I knew bought a brand new one  sometime around 1979/80 for commuting to work- they looked great value and that bit different to other bikes at the time.
I sat on one at the local dealers but it was rather small for me at 6ft 1in with a 33 inch inside leg- that was my excuse at the time in reality it was just out of my price range.

Unfortunately, the first start after closing the cases and putting everything back together did not go exactly as planned. In order of events:
- After putting fresh oil in, I have primed the oil system (sparkplugs out) by turning the crank from the right side of the engine.
- Oil light went out, so I should have pressure
- Spark plugs in
- Gave it a shot with the startermotor: everything sounds fine
- Added some more oil to bring the level up to max
- Opened the fuel tap, start: immediately sprung to life, no weird noises. Adjusted the choke so I had a nice stable 2000 rpm to let her warm up gently
- Again, no weird noises, even the valve train sounded a lot less noisy (with the new adjuster)
- After what must have been around 30-40 seconds, there was a zzzzZZPP sound and the engine stopped.

I feared the worst, so put the bike back on the lift, she cooled down a bit and I tried cranking it over from the crank nut. Seems pretty normal. Gave it a go on the starter motor, also sounded pretty normal (even wanted to fire, but I didn't give it any choke or throttle)

I don't know what is a wise next step now, in order to understand what happened. I "only" opened and shut the cases, and replaced all oil seals. So logically I would think maybe a crank bearing gave up (maybe it didn't like the heat from the welding, although the entire case was pre-heated and clamped down on a fixing table to avoid warping).
But a zzzZZZPPP sounds more like a piston to me (?). I would think knocking or clunking is how a bearing sounds....

All advice is welcome.
