My boy got a present for Christmas that he wasn't expecting:
Over the next couple of years, we're going to build him a moped!
The goal is to get it done by the time he's old enough for a license.
I found an old Bing on eBay, which we cleaned up and bought some new parts for.
And we've taken apart an old E50 engine. Several parts are damaged or missing, so we'll be replacing them.
I'm not sure what to make of this dust pattern on the cylinder wall. The wall is smooth to the touch, and it doesn't seem to be real dust. It has a couple of scores on the wall, so I'll probably not be reusing it anyway. But it is a curiosity.
