The oil supply to the engine goes past the oil pump gears, then past a spring loaded ball bearing onto the crankshaft and big end. It's usually crud or a pit on the seating for the ball that allows the oil past. Cleaning the seat and oil ways, followed by reseating the ball usually works(well for me it does).

PPS I talked to the owner at Feked and asked him to explain how one of these taps could work on one of my 40's mag bikes.....and he agreed it can't!!

yes Rob, my understanding of things is,,the oil seeps past the gears in oil pump, into the oil gallery that feeds the crank ,the ball and spring are also off the gallery . no doubt  someone  will give us the definitive  answer. I have replaced ball and spring with no effect,  so I have fitted  a tap, I don't use the c much ,but when  I want to use it it is ready to go without draining the sump

Rather like the inevitable cries of "change the oil every year" even when the bike's only done maybe 500 miles since the last oil change.
They were never so cossetted in the first twenty-odd years of their lives when it really mattered.

Quite so but back then there was a BSA dealer in every shopping village, a bike breaker every few miles and a bike shop on every street corner.
So when something went bag you could push it a few miles buy a not quite worn out part for less than a pint shove it on & continue along your merry way.
Now Australia has no BSA specialist shops at all , bike breakers do not hold vast stocks of C series parts, all the motorcycle shops on street corners sell HD regalia.
Thus things have to be a bit different  .
I use 2 systems
Some of the bikes have extended sumps with magnetic brain plugs and these get removed the instant I come back from a ride.
The plug will sit on the fuel cap & the bike gets covered with a cotton cover.
When using next time, the plug is replaced & oil collected underneath may get returned to the oil tank if it looks reasonable , or I top up with fresh oil.

The other bikes just get left there & when needed again, get started and allowed to idle till the excessive oil has been returned to it's rightful place.
The sole exception is the M 20 where I remove the primary oil level bolt to stop the clutch being drowned.

all geared type oil pumps seem to have this problem but my triumph has a plunger pump and that doesnt suffer .my Norton dominator empties the oil tank in 2 or 3 weeks .

By the very nature of a gear pump.it will pass oil when not moving.

Plunger pumps are a better design all round. Less moving parts, no problems with draining down and virtually ever-lasting.

Yes I had heard that the 'magneto guys' have developed a system with a "points cap cut out" ......But none of it's for me though! Thanks Ron

What is never mentioned in service details is occasionally you have to recut / refinish the seat for the ball.
So from time to time you need to CUT the surface to remove all of imbedded crud and in particular the crud that gets hammered into the surface because people do not bother to clean the seating surface before shoving in the ball  & punch before smacking it way too hard with your 20 lb hammer.
A spray gun brush works very well for this.
