Crankshaft is back from balancing. Marine Crankshaft inspected, magnafluxed, dynamic balanced the crank and micro polished the journals.  $240.00 with one way shipping back home.  I had wanted more exotic work, but Marine Crankshaft wasn't on board with going nuts. I can appreciate being told why and when I'm wrong, especially when it saves money. I have a windage tray/sloppage plate going in too.

here are some pics and the piston rod bobweight card.

They drilled the hell out of the weights. What % overbalance did they set it to?

I have no idea to be honest. sent them everything and told them what I was after and a wishlist including knife edging, polishing etc. Marine Crankshaft poo-pooed most of my ideas and only did what they though was needed. Probably saved me a good chunk of change too.

The crank still heavy. 20 lightening holes is like scraping a few cubes off of an iceberg.

If you add up all of the weights you get 1421 grams. Multiply that by 52% (a common balance factor for Guzzi engines) and you get 738.92 which is close to the 743.6 bob weight used. 52.3% gets you even closer - 743.18.

Engine is starting to go together. Here are pics of the Trankontinental clutch/flywheel assembly. The entire set up weighs 7.54 lbs.
If you look down into the motor, you can see the aluminum windage tray and the filter poking through it. Tom Hull machined an additional hole into the rear left side of the windage tray to ensure all of the oil drains back into the pan and doesn't pool on top when the bike is parked.
