The Yamaha part# is 371-14966-60-00... I have never seen them in-stock anywhere ,  for sale online, and of course the rebuild kits do not included them.....
   
 I am looking into a "fuel safe" material to mould  a few sets ( I have one good set of these in my '74,  yet have another set of carbs without any right now )

Does anyone know of a fuel safe resin that can be purchased in small qty...  - nitrile, fluorosilicone, or urethane that remains pliable when cured?

Here's a plug that Yamaha still carries that can easily be made to work on the TX/XS500 Keihin carbs. They are used on the original Vmax, XVZ12/13 and XV500/535 carbs. Part number 22V-14968-00-00. It's a little too long so you have to trim a couple of mm off the plug end down to 4.0mm like the original so that you won't block the fuel feed passage to the jet.

Good find Guy! 

Similar 22U-14968-00-00 plug went into quite a few V-max and Virago models, and looks like it would fit apart from the shoulder possibly needing trimming this time....

Must admit though, I was originally considering these at probably a couple of pence each!

If they don't melt from the exposure to fuel then they look like a much cheaper choice. The Yamaha ones are pricey but they will stand up to gasoline and alcohol.

I was wondering since these are Keihin carbs if some Honda models might use the same plug?

Yes, I think that one could be made to work too and is actually found along side the 22V plug in the same carbs. The 22V has the right sized head on it though.
