CB750FOUR OIL PRESSURE

ADEEL MIRZA
Any idea of checking the oil pump pressure of Honda CB750 Four K4 (1976 model)?

You can check it by installing an oil pressure gauge on the engine. It goes on where the large nut is on the right side of the engine above, and to the left of the points cover.

What should the pressure be? Min and Max values?

Don't know the minimum, but the maximum should be 72 PSI @ 7,000 RPM, as per the FSM (for the DOHC's, I assume the SOHC would be the same, though).  Cheers!

My oil pressure tops out at about 75psi. SOHC's are dry sump so it pretty much runs a constant oil pressure. The gauge will fluctuate some,but about 75 is the max norm.
