Actually that's a good point, and I also could use the help the deeper it gets. I'll send him a link and have him join in.
OK, I've got the case split and here is what I've found so far...
Crankshaft - This thing is definitely whacked. The primary side actually has .010" TIR; the stator-side has .027"; the web/counter-balancer(s) show visible wobble (left/right). Heck there are even some jaw marks where someone clamped the crank in a vice! I've already sent an email to Lyn Garland at Vintage Specialties and he gave me pricing for a rebuild (around $600). But I think I'll email him back and see what his concern level is about the condition of the crank. I do have a local option for a used crank and stator for $120, which should be in better condition than what I have.
(vice marks in web - also note how the bearing wasn't positioned/rotated correctly by the person that did the last tear-down, the raised dot is supposed to mate with machined notches that are in the front where the cases meet)
(points cam with deep pits)
Pistons - they both show signs of scuffing but there is no damage to be concerned about. They also measure 2.116" (53.76mm). I believe this is the stock size, even though one of them has #5 next to the arrow on the piston crown. The cylinder bores also show some slight scuffing and measure 2.128" (50.05mm). I plan on doing the top end too and Lyn Garland recommended Bore Tech in Ohio, so I sent an email off to them for some info and pricing.
(piston top - cleaned up a bit with a wire brush)
Obviously I wasn't expecting this from a bike that is supposed to have only 6K miles on it, especially since the rest of the bike is so clean. Oh, well...next up cleaning the cases and more inspection.
