Not much to update except new crank bearings are ordered, and I'll probably get a gasket kit soon. Need a new piston also. The gas tank is also in need of a liner, and i'm kinda thinking SL175 fenders will be a nice change too. Little more trim than the crusty oem ones at least.
nice project while youi have the crank on the bench you should check the big end of the rod for radial clearance
a dial indicator is the only way really a bit tricky but if you hold the rod gently sideways against the thrust washer then you can push pull to get a reading
really needs to be done flushed clean and dry,so the grungy oil doesn't interfere with the measurement
somewhere you could find an upper limit but anything over .003" is getting close to all done
