I’d probly notice the type of sealing washer and offer some valuable technical advice, like you should use different washers on either side to counteract engine torque .
Edit-before we go off the rails, it’s the weight, not the color that makes it plausible ….

Good points.  Should probably use Aluminum bolts also.

I was thinking HHCS on right, SHCS on left......  One metric, one US standard.....

Brass washers on a Guzzi? Never! :smiley:
Laverda used copper washers under head nuts, and looks proper but preferably on an Orange Laverda.

I’ve always admired those and that one is a beauty.
As far as locking fasteners, a cross thread is one of your better safeties.

That bike is a beauty.  One of my favorite colors for motorcycles.

For the record, I was one of the early advocates of copper and Laverda orange as proper Engineering!

I was talking about that very bike a friend in Canada owns (owned?) yesterday.

My comment was, "wasn't that engine a big ass copy of a Honda Superhawk 305?"

He said "Yes it was, Laverda used a photocopier to enlarge the Honda blueprints!"

Laverda were not shy in stating the Honda CB77 was one of the factors that led to the design but beyond the very similar casting details the layout of the motors and ancillary components are quite different. Laverda use a generator and their large electric starter ( no kickstart), right hand shift, location of points etc…
All I can say is once tuned properly and with bar end weights it’s reasonably comfortable. It still has a buzz to it and it’s quite heavy, short steering lock doesn’t lend to U turns. Sounds great though.

Is that the same crank configuration as a 1970's Norton?  I always loved the way they sound.

My buddy near Toronto says it is bulletproof engine.  Old guy, been in bikes forever, originally from England.  He is one of my go-to-guys when it comes to the 70's machines I was too poor to experience back in the day.

He still owns that real cool yellow Moto Guzzi 350 "enduro" that I posted pictures of previously.
