What pressure is the oil pressure relief valve to be set at?

From recent testing by a builder of oil pumps, 3 shims = bad, 2 shims = a bit too high, 1 shim = ideal, no shims = still more than enough to achieve enough pressure. Thankfully, if someone forgets to put any shims in they will be OK.

Do you happen to know why shims are specified for Norton but not Triumph?

According to the workshop manuals, 45/55psi. I assume that this is with one shim but do not know for sure. Since the pump is a gear pump the pressure is quite low at idle and the OPRV is doing nothing until the RPMs come up quite a bit.

I've seen gauges show a max of 60 and a min of 0. Of course, it not really 0, as the same bike with a oil pressure switch set to 4-6 PSI shows that there is pressure.

It should be with however many shims it takes to produce the required 45/55 psi oil pressure.
