Anyone tried this? Seems like a reasonable idea to keep the oil in and to be able to reuse the plugs.

"The factory would punch the center of the welch plug to flatten it out, expanding the O.D. and sealing the system. When the welch plug is installed this way and if it ever needed to be removed for maintence or whatever, you would have to drill and tap the welch plug in order to pull it from the swingarm. We have found that placing a clean dry welch plug into a clean dry swingarm end and putting a bead of silicone adhesive sealant around and over the plug, will seal the end of the swingarm and hold the welch plug in place. This allows for easy removal of the welch plug by removing the silicone and using a strong magnet. Since the swingarm ends are not visable, using clear silicone does not distract from the appearance of the bike."

I would think a nice bead would do the same versus the big smear that they show?
 
It works for a few years, then the silicone comes loose and the plug falls out.

I have done this on my MK2a for fifteen years. It works well. Just make certain that the area is completely clean before applying the silicone.

I've tried it, and ended up using epoxy. Aesthetically it looks better than an oil leak.

I've had the welch plugs out of my MKII once in 40 years. Don't expect to need to do it again. I tapped them in place and ran a bead of clear RTV around the outside.
