Sometimes I cringe when I think that my bike's previous owner had intended on just cleaning the carb and seeing if he could get the CA95 to run. Based on what I now know, he'd never have succeeded, but as I dig deeper with this restoration, it's clear that he would have only made things worse.
While my cylinders are at the machine shop getting bored .25mm over, I decided to take apart the speedometer drive. I'm glad I did, because deep within the grease, I found some little metal surprises.
I found what used to be a thrust washer, all ground up and settled into all the corners and between some gear teeth. This just reinforced my belief that everything needs to come apart for inspection before these vintage machines go back on the road.
Fortunately, the worm gear teeth are in decent shape, so I'll get another thrust washer and put this back together with some new grease.
