Astrid: Start and Start Again

Pulled the camshaft to do the pencil test and confirmed it's an S90 grind.  While I was at it, I also re-gapped the plug (narrowed it a bit), set the exhaust valve clearance (opened it up a bit), and set the static timing back to the mark (it was a little advanced).

Bike started with three kicks off of 6.33V, but also unfortunately found some oil leaks.
