The scooter engine reached it’s state of maximum entropy this round, and is coming back together.

I used a torch for the first time to install a replacement bearing for the fried fly side one. Let the bearing sit in the freezer while I braised the case with a tiny torch. It went in, though not the first time, but the second time, with some gentle persuasion and some refreezing from an inverted can of air (used to clean computer equipment – a tip I found on YouTube).

I was uncertain what should be lubed and how it should be lubed. I had to stand back and look again at how the system works, I figured it out. Gears on one side and explosions on the other. So, yeah, motor oil and two stroke oil everywhere.

After I “offered up” the fly side case with a rubber mallet, I pulled it back apart, and realized I needed to install the crank race separately, whispering the mantra “Patience, and gouge not.”

The next step is installing the piston and barrel. I’ve chamfered the barrel ports so I think maybe they won’t catch the rings, but maybe chamfer some more? I dunno. Peaceful times in the garage with a file.

We will see.
