Hi V11 Max
Unfortunately I am unable to shed any light on your current predicament, but I can offer you a warm welcome aboard.
There are a few Guzzi enthusiasts lurking on here which may be able to throw a few cents worth of advise in, I would also suggest (if you haven't already), find us on Facebook:
Grease Monkeys - Bike Builders Club
Ask the same question there, and you may very well get a quicker response.
And a lot of advice... good and bad.
