Everyone, thanks for your input!   I replaced the thermostat, made in
China, with one I bought at FLAPS, also made in China, and noticed an
immediate difference.  The engine warmed in a very reasonable amount
of time, more of what I vaguely remembered from my previous '85 Westy,
and the temp never ventured above the LED this time.

And also thanks to Vanagonauts website for their nice write up and
thermostat replacement tips.  I did it in 20 minutes at lunch.
