I fitted a tap some time ago, and although it appeared to stop the wet-sumping, it seeped a bit of oil, albeit very very slowly, at the tap. I tried a tiny bit of goo on the olives but the leak continued, so I replaced the tap with another new one (same kind, which was probably a mistake) but the slight leak persists. It's not a big problem so I haven't done anything further, but from time to time I think I might fit one of these (see photo.) Are they absolutely reliable?
In the meantime, to help me remember to turn the tap on, when I turn it off I attach a bit of string with a makeshift penants/flags on (a bit of duck tape folded over it), and a loop at each end - one loop goes over the tap, the other over the choke lever on the handlebars, and I loop the middle part of the string around the petrol filler cap, so it's very visible when I come to start the bike (I think I got the idea from someone on this forum.)
Any thoughts on the switch in the photo?
