Sounds like a plan, but the air filter was new and the intake is clean.
There could be sand in the crankcase, it was a very dusty rig from a dry
climate.  But it had minimal rust!

I'll spend the extra money for the purpose of increasing the collective
knowledge, even though I hate to put any more money than necessary into this
engine, which is headed for the metal recycler next fall (no earlier I
hope!)

Sometimes these reports can be a bit scary. The silicon and sodium is a sign
the air filter is not doing its job and the oil filter isn't helping. Also,
considering the engine with that mileage you are using the wrong oil. Now
for an experiment! Change the oil and filter. Use something with a higher
viscosity such as the Mobil 1, 15w-50. Get a good high performance oil
filter such as the M1-205, (yes I'm partial). Replace the air filter and
clean the air inlet tract as much as possible. Do the test again at 2,000
miles. You should see much improved values.

Just in case anyone is interested in what the oil looks like in a poorly
maintained '85 Westy with 140k miles after 2000 miles:

Good news is no coolant (probably)!  Bad news-lots of iron, lead and
aluminum.  No surprise with the low compression in two cylinders.  Iron
could be from a worn cam and lifters as well as cylinders and rings.  I'll
install an oil pressure gauge next to see how bad the bearings are.  Still
hope to get 3000 miles out of it this summer.
