I am using an oil pressure gauge on my G/S and

heat engine 90-100 C, oil castrol gtx 20-50

ıdle 1000-1500 rpm 30-40 psi, (2 - 2.7 bar)
riding (mostly) 3000-3500 rpm 50-60 psi (3.4 - 4.1 bar)

Idle looks fine. Midrange looks fine, high end maybe too high. Gather other opinions. Got a clean oil filter on it? What are the pressures with the engine cold (to DX the pressure relief valve)

Cold - up to 160PSI peak in the first seconds, quickling going down to about 80PSI at idle or so
warm idle - less than 20PSI
4000rpm - around 50-60PSI depending on riding condition

Instrument: cheap 0-160PSI air gauge, non-calibrated

That high pressure at start-up make me think that revving the bike at start-up might not be the best idea!

You can say that out loud, Ken. Once you see your needle on the other end of a 270deg/160psi scale you close the throttle pretty fast!

...and is the cause of oil filters that look like someone squeezed them very hard.
