Low oil pressure in 2001 Classic VX1600

[geoff1]

The pesky oil pressure issue on my 1600 VX 8 valve seems to be getting worse- was 40 psi cold 20 hot then 20 cold ten hot then ten cold and naff all hot though warning light does not come on- revs make no difference-  new mechanical gauge so its not that- couple of minor oil leaks but no smoke or smells or rattles and compression good on all cylinders plus no petrol in the oil and the engine to all intents and purposes seems happy but I am not-  any ideas? looks like another trip to see Ian at PT Sports
