Only one tubing type listed as usable for motor oil, but none rated for operation above 80c temp.
I have not found any oil rated 130c or better pumps under $150 and using 12vdc at 2+ amps. I did find some used 12vdc oil pumps for turbine cooling in turbo equipped cars.
Another thought, how much oil can we have circulating in our cooler system without also having some additional oil storage? Can we use a one-way valve to prevent oil drain back and just add enough additional oil to fill the cooler, pump and lines. Also, what about a real oil filter while we are at it?
It's a beautiful day here in STL, MO. so I'm going to give the brain a rest and go ride.
Lets keep this thread rolling with the good ideas.

Sprocket, good idea, got me picturing the engine. If I remember correctly, the oil from the oil pump flows up to the head though the passage for a head bolt or stud. It returns, after lubricating the cam and valve components, down the cam chain passage to the crankcase.
I have noticed several mentions (in my brief time here) that the cam chain passage my be one of the hottest areas of the cylinder wall, so the oil returning to the crankcase may provide added cooling.
I do know enough about the casting internals too make any sense of what it would take to divert the oil pump output through a cooler before it arrives at the head.
I do know that I would pay someone $100 for a do-it-myself kit to keep oil temps at 230 F average and 260 F peaks
More comments welcome

I would start with looking for a ground problem.
