Fool proof, no fuel no going anywhere, even did the same idea to my regular mount my "B" but it's not the same easy photo shoot as the "A"

I use a brake pipe clamp when the bikes is going to be stood for a while. You can't forget to remove it on a Prince because you have to remove the side panel to access the pipe. Leave the side panel on the seat.

A little OT, but I used a section of automatic transmission cooler hose for the pump suction feed. It was a bugger to get over the pipe, but I figured that on cars they see hot high pressure fluid for many thousands of miles and are never replaced, so it must be good on a Vin.

Having put up with sumping and resisting fitting a valve or tap for too long, I confess I have succumbed and fitted a tap. I like to try and maintain a standard appearance so I made an adaptor and fitted the tap as close to the tank as possible. No room for the operating lever here so I made a key to operate it by.
My front brake handle bar lever has a redundant hole in the blade for a brake lock . In the garage, the 'key' when finished will occupy this hole, that together with a bright red cord preventing the bar end mirror from folding out is my safety set up.

I realise it's not 100% fool proof but I am ok with it . On the plus side , not having to drain the oil before a ride is something of a novelty and a real pleasure. Another bonus is that the tap is very discrete and without its lever virtually tamper proof.
