Red: 7.5 Volts

Realized that if I was short on voltage with the engine running and the lights on, then why not add a couple extra?  Seemed like the low horn volume when running was simply due to the low volts.

So rigged up an extra D battery to clip into the existing harness.  Tested ok, so then soldered everything together.

Test run showed a much better horn volume, though still not super loud...

Red: Close Call

Cut a gasket for the left crankcase cover using the Fel-Pro cork-rubber 1/16" material.  A bit fiddly with all the holes, but actually not as much trouble as I would have thought.

Drained the oil and installed it, but in doing so discovered the chain was covered with small metal filings!!

Both bolts on the front sprocket were so loose they were wobbling in place!

That then caused the sprocket itself to be loose and grind.  Luckily it seems like the teeth themselves where ok.  The grinding took place lower down.

But had to then completely remove the chain for cleaning.  Brushed and scrubbed it and hosed it down repeatedly until all the shavings were gone.

Put LocTite on the bolts when re-installing as well.  Lubed the chain as usual.

Close call!
