Cool. I like to find these things out. Guzzi parts can be extremely pricey.

Chevy small block valves will work if you cut the stem lenght down and recut
the keeper groove. I did a complete valve job on my Ambo for $40 years ago
by adapting common automotive parts.

John:
I hadn't weighed in on this issue yet, but this reminds me of when
my wife and I rode down to Mid-Ohio several years back, she was on the
'71 Ambo when it suddenly lost power while cruising around 70mph. She
nursed it to the next rest stop where I found that one piston had shut
down. After determining that it was still getting gas and spark and
that there was nothing else to do, we fired it up and she limped it
about 40 miles to Mid-Ohio on one cylinder.
The autopsy revealed that for some reason the valve kissed the
top of the piston and bent it enough to hold it open. After mentioning
the cost of a new valve to my machinist brother, he insisted that he
bend it back. 5000 miles later and that valve is still in there.

Thanks to those of you who responded with suggestions. My gut is
it's a valve. The sleeved are stepped and therefore can't move.
Piston clearance is also correct so that pretty much leaves the
valves.

Evidently there was a valve spring binding issue on the early V700's
which is what I have. It would seem like this would be RPM related
though, not load related.

Thanks again,

John
