I had a A7 with an engine that was badly damaged by the previous owner fitting a ball valve in the supply, which then stuck & starved the engine of oil. Fortunately repaired by the previous owner.  A factor that owners forget is that when starting, they, quite rightly check the return flow. BUT, to begin with, that flow is only what has collected in the crankcase. It does not mean that oil is being pumped into the engine. One must continue to check until spurts of oil continue from the return pipe for some while to ensure oil is being pumped into the engine & scavenged back.
As has been said before:-  Ball Valve- No, No, No, Sump Drain Plug- Yes, Yes, Yes. Get on your knees & worship. If you are married, you will be used to it!

Great feedback guys.
Thanks to all.
Great idea dutch regarding draining the tank post ride.
I might put in a tap to do just that.
But the same logic implies that I may forget to fill the tank before the next ride.
Some guys always have to learn the hard way.

SRM Sump plate with a drain bolt-the ONLY safe way!

I went this route.  If the bike sits for more than a week, I'll drain it.  Less than a week, there isn't enough to worry about.  Simple and Safe.

 I really don't think it's such a good idea, but has to be better than some hair-brained ideas and I don't and have no need to do it, but is simply an option. Obviously one would strap the oil container to the crank peddle or twist grip....or similar *dunno*

 One thing I have done, is utilise a length of 3mm SS filler rod (welding wire), cut some grooves in it for level indicators and leave it in the oil tank as a dip stick; surely people look in there occasionally to check the level, like before use..??

Here is the key-in-valve setup.
Hadn't started the bike three months, no problem, just turn it on and go, no oil on the floor, no messy draining and refilling, no smoking engine due to over filled sump.

this is the off position. You need to use the ignition key to turn the valve off. Once off, the key won't come away from the valve until oil flow is turned on again


On position. I leave it like this unless the bike is going to sit for an extended period.

Nice work Glen.
