I have not done the seals one one of these engines yet. But from the parts manual, it appears easy to change in the frame. You will need a flywheel puller and some sort of pinion gear puller of course.

Most of my vintage 2-strokes have bad seals, especially the dry side. But if yours is smoking and using gearbox oil, of course it would be the clutch side.

When I had one new I ran synthetic oil at much less than 20:1. Likely 32:1 but I don’t remember anymore. Using a very good modern synthetic, I speculate you can run much less oil than that easily. But I have not tried. I do run 50:1 with Motorex full synth on my vintage OSSA Super Pioneer and it works well. But a lot depends on how hard you ride it and how hot it gets. It is very critical to get fuel mixture correct. If it gets a little lean- bad things happen in a hurry.

Around 7 volts if I recall. I think the 8 would ‘cook’ the tiny little battery pretty quickly.

A 12V nominal charges about 14V.

I measured, and it appears to be 22 x 1.0 mm.

I am going out to local shop and see if they have one so I can be certain.
They didn’t have one. I ordered a kit with a bunch of different sizes. Should be handy
