Progress.
Engine back together.
Work flow for getting the piston installed, since i cant find it anywhere on the site.
I took the starter out to do this, easy, 2 bolts. Rotated the crankshaft from the generator bolt until it was just below TDC with the crank on the rear side of the bike. Then put the starter back in. Now the starter is resisting the engine backdriving, so you can put a bit of downard force of the crank arm and it wont jut plunge down into the crankcase.
Now, install the rings in the piston, as per manual, and attach piston to crank with wristpin and spring clips. New Gasket on, drop the cylinder jug over the cylinder studs until it rest on top of the piston, which should be well oiled, as well as the cylinder. Now, one by one, squeeze the rings as tight as possible by hand while jiggling the cylinder down onto the piston. This is positioning the crank arm jsut on the rear-tire side of TDC helps, lets you push down on the piston a bit. Didnt take much, as the tapered bottom of the cylinder sleeve does a good job of easing the rings in.
Worked quite well. Then just rotated the crank a bit to make sure the piston moves smooth.
