UPDATE
Spent a good deal of this week waiting on parts, poor USPS must be having a terrible time this holiday season. Did manage to get a couple of things knocked out:
1) The jugs and pistons are at a machine shop - should be finished within a week or so.
2) Installed the valves with new valve seals. Everything checked out pretty good here.
3) Cleaned and rebuilt the clutch. Totally destroyed that keeper wire on the clutch boss, what a nightmare of a piece! My thanks to
@5twins and
@gggGary for helping me out with this.
3) Polished the left and right cases - was pleased with how they turned out.
4) Installed oil pump and tach assembly. I was not able to get this O-ring inserted. It is a new ring and well-lubed, any suggestions? It keeps folding-in when I try and insert the tach housing into the case.
5) Cleaned up the rotor and discovered it has low resistance. I have read
elsewhere in the forum that you are looking for 5 ohms across the rings. This one measured about 3.5 ohms. I assume this needs to be replaced? Options other than MikesXS?
6) Prepping for crankcase assembly. Got the crank and cam chain in, spent about a half hour getting the bearings seated correctly, but finally got it seated. Had to come up with a way to mount the top half inverted. The wood vice on my workbench worked out very nicely along with some tubular steel. I decided to replace much of the hardware on the lower end and am generally going to try and replace as much as is practical with stainless throughout the rest of the build. This assembly seems like the sort of thing that could go wrong in a hurry, so I am trying to get all my ducks in a row before attempting it. Some liquid courage may also be necessary.
Lastly, I did come across an issue with the #4 starter gear. It looks fairly worn, like it has been skipping on the crank teeth. I discovered this
post that claims all you need to do is pinch the spring, even for worn gears. Anyone have first-hand experience with this fix? It almost seems too good to be true...
Thanks all, will keep you posted!
