finally making progress!
MSA were great, got a new set of NPR rings to me by 10:30 am so i was able to get the pistons assembled and installed. bottom end done, head on, timing chain installed. i was pleased to see that the slack side chain guide was able to pick up all the chain play even with the head shaved .060 and no tower shims. the cam gear is set at the #1 position and is about 2 degrees advanced with this setup - i figure i'll leave it as is unless there's a compelling reason to get it dead on with an eccentric. i've advanced cams 5 degrees with good success on ducati twins - not sure how the L6 responds to this...
spent the better part of the afternoon cleaning up the valve cover - it ain't show quality, but definitely nicer than it started out. a PO had the bright idea to put a clear coat on it, which was partially peeled and yellowed (looked like spar varnish) and was a major pita to get off - an hour with the wire wheel.
for the build i bought a little $50 bench-top parts washer and made an aluminum shelf on the exterior of the garage to keep the fumes outside. it works great for cleaning things up as i go - i give 'em a scrub, dry 'em off then hit 'em with WD40 to stave off flash rust. filled it up w/kerosene which works well as a solvent, very low odor and doesn't evaporate too quickly. parts come out looking brand new and it feels great to build the motor without all that old sludge, grit & baked-on oil all over everything.
tomorrow i hope to finish up with the front cover, water pump, oil pump, dizzy, alternator & motor mounts. then i need to replace the seals & gaskets on the 5-speed, give it a clean-up, install the flywheel & clutch and join it to the engine. pics from the last couple days below:
