Wholly Guacamole, getting to the valves on this puppy is quite the project!
It turns out that all of the valves are right a spec save the verticle exhaust opener, so I have to wait till the shops open to get a replacement.. It is 2 or3 loose, butt I have a piece of feeler gauge that is 2, so I was thinking, I could cut a circle and fit it under the valve shim, and it would be just about right!

I acquired the needed shim after some "issues", and got it installed in the motor. This bike has a chamber that the crankcase breather vents into that then feeds the airbox. The chamber had a good sized hole melted into it, looking like it had rested on a hot cylinder head. Upon reassembly it was quite clear of the head so I have no idea how it became melted, butt I filled the hole with JB weld so no more unfiltered air into the motor. Only now it idles quite a bit slower than before.
At least it does run!
As I worked on the bike I had many thoughts along the lines of "why did they do that?" Removing the fuel tank was easy save for the quick disconnects fighting me at every step. Then there was the air box that had dirt lying in the bottom... The hole in the breather box explained most of that, butt when I went to remove the screws holding the nose piece on the corrosion made them very reluctant to give up. Getting them out proved to be easier than getting them back in, though! This was designed to be assembled without the electrical system in place, it would seem!
There is a tradition in the vintage woodworking tool community that a tool does not belong to you until it has tasted your blood. The Bimota and I are now inextricably linked.

Laughing Yeah, it's definately a love/ hate relationship with these beauties.
