Other then polishing the side plate, etc., How does one increase oil pressure in that pump without doing something to those gears?
I have an extra pump I'd experiment with.

I had three. I took the best gears and used a feeler gauge to measure them. The tolerances are in the manual. There's also a thinner gasket but they are hard to come by so I used the best one I had.

When I did mine, I noticed how thin the stock gasket was...... I also noticed the gasket in the Athena set was typical 1/32" paper which seemed about twice as thick as the stock one. I reused the stock one. I suspect using a 1/32" thick gasket could really screw up the pressure.

I'd check the pressure first. Another thing to check is the O ring between pump outlet and cranckcase.

These roller bearing cranks can tolerate low oil pressure, the smaller 400-750 aircooled fours with their plain shell bearing
cranks can't.

Test it. There's a O ring in between the case halves too. That being the case. the cases must be split to fix it.

It's back to normal now. The light comes on and shuts off when it starts. Might have been the heat since it first appeared 100 miles on typical Ga July afternoon. I plan on keeping an eye on it, investing in the oil pressure gauge and a temp gauge.

Find oil pressure gauge and check pressure at whatever RPM book says. Use heavier oil.
