I am finally going to have to do something to cure/improve wet sumping. It's many years since I restored my Rapide, so my question is, can the plunger OP30 be extracted without any other dismantling ie will it clear the G50 plate?
I can't bring myself to fit a anti sumping valve, a tap maybe with some kind of safety measure incorporated . Has anyone fitted the combined tap and ignition isolator from Kingpin Components or the Magneto Guys ? Pictures of members tap/switch installations would be great and much appreciated.
Thank you.

There have been quite a number of the Kingpin taps fitted to Commandos and other wet sumpers on the Norton Access site.
There are also a number of similar type units sold by others. Lots of these have been fitted as well.
I would guess that by now a few thousand of these taps have been fitted. Kingpin is often out of stock, then they get a batch of 100, then they are out of stock again. There are a lot of wetsumpers out there! Gravity is a constant.
For years now, on the Norton site, there have been dire warnings of catastrophic destruction if one of these taps so much as comes close to your bike. Some of the doomsayers will start to foam at the mouth with any mention of one of these valves.
The reality has been zero problems, unless you call not having a full sump and a puddle of oil under the bike a problem.
There have been some engines ruined by the automatic type spring and ball check valves and also by manual taps installed without an ignition safety interlock. Sounds like Ted Davis had a manual tap without a safety.
Those and the auto check valves are very risky options best avoided.
But it's been 15 years or so and we are still waiting for the first report of an engine ruined by the type of tap you are considering, a manual tap with ignition interlock.
I'll dig out a photo of one I conjured up. It's a bit different in that there is no electrical switch or wiring involved, but it still disables the ignition when the tap is shut.
