Don"t install the valve.If you insist on doing so do not install it next to the tank.That way oil below the valve will drain into the engine and you will have an empty oil pipe between the valve and the pump.When you start the engine it will be several minutes before the pump manages to draw oil via the empty pipe and the valve into the engine in that time your big ends will be without oil pressure. They will not last long.If you install the valve put it directly on to the the inlet pipe fitting.Best grit your teeth pull off the timing cover and investigate the problem.A slow leak into the engine seems almost general

i believe the oil pump should be in top condition to minimise wet sumping.i have seen oil pumps mounted on studs,others with bolts.with the bolts i drill holes in the bolt head so i can wire all three bolt heads together after tightening.in theory this should prevent pump bolts vibrating loose.a proper fitting gasket is essential.the later cast iron pumps are best but hey if ya can afford an srm pump all the better.an oil filter on the return line goes along way to keep the blood clean,sump plate with magnetic drain plug also a useful addition.a regular oil change is also a good habit to get into.

Just my 2 centimes worth; my A65 had not run for at least 8 years when I got it, I spent my time getting it running and whilst stripping the primary side NEVER looked behind the inner cover on the timing side. I put up a note on the board that I had filled the tank several weeks before start up and the level did'nt move, I had expected some wet sumping so why no oil drain into the engine? The concensus of opinion was that as the pump had not drawn oil there may have been an air lock in the feed line ; I run the bike regularly now and even if it is left for a month or so the oil level in the tank does'nt drop appreciably, all I can suggest is get in there and fix it because losing this much oil past the pump in such short time strongly suggests something is WRONG which won't be fixed by an inline valve.

Working from memory here (NOT the most reliable), don't Velocettes use a spring-loaded check valve on the feed line just below the oil tank?

I have this problem with my '40 Indian Scout. I've been thinking about installing a manual valve at the oil tank and wiring it through the ignition switch. That way it would only start with the valve in the "ON" position. Anyone tried this?
