Dave Swanson:
The bike that had both feet in the grave is starting to crawl out.

Dave Swanson:
The timer had the usual divot which I machined out on my lathe.

Dave Swanson:
The transmission was laying in bits in the bottom of one of the boxes for years, but it wasn't missing anything critical.

A new 4th gear was purchased from Harpers with the updated bronze bushing.  One of the shifter forks was severely worn, and good used shifter fork was purchased from The Guzzi Doctor.  The layshaft output roller bearing was replaced. 

Patrick Hayes modified the pre-selector housing for an o-ring seal. Patrick also machined and installed the stainless sleeve for the throwout system. 

It shifts on the bench very nice.

Dave Swanson:
Always a big step.
