This little Sherco motor is starting to look a little healthier. That smokers cough has almost disappeared and it seems to have a lot brighter disposition!
The combustion chamber came up remarkably well. The dirt flaked off reasonably easily, and some scotch-brite and WD-40 put the sheen back into the dome. New seals, bearings, and assorted rings, pins, clips etc – chemically cleaned, plenty of elbow grease and it’s starting to look like an engine again.
