Come morning, I descended to Silver City and knew something else was wrong. Sure enough when I stopped in town at the visitor center it died. The ground for the coil had evidence of arcing and half the tab was missing. The gap between the disconnected wire was grounding across that gap. No wonder my mileage was down to 89mpg and had a little blowby.
I was able to do some service on the scooter and surprised myself that it has about 1700 miles on it since leaving LA and 2000 since the last oil change. After reuniting the muffler and scraping the crud off the magnetic drain plug, and a headlight allignment, Tortuga should be ready to Mess With Texas!
