I also like the detail regarding testing! :puke: :lol:

If you would like to edit your post to include my images, that's fine. It would allow you to shorten your post a little. I'll also be editing my post to advise people to read yours.

The subsitute feul cock was great info too. From the pic, the gasket between the fuel cock and the tank looks a little thicker and who knows, it might change the reserve tank a little but 18 dollars??!! I would strongly consider that next time.

Try to update this in maybe a year or so to state if it has had any problems and if it is still working. I wonder about the bevel issue as I'm sure you do. Does Suzuki MAKE a beveled o-ring or does it sitting in there change its shape?

So a quick update. I've had the o-ring in the petcock for about 2 weeks, and I have had no issues at all. The bike doesn't leak, and doesn't starve for fuel under full throttle, so the o-ring is sealing and unsealing completely normal. I also disassembled the petcock to check the o-ring's shape, and it seems to have a tapering to it now, although not quite as much as the original o-ring had. Which leads me to believe that the o-ring may never have been tapered from the factory, and may very well just do that with age to a point where it will no longer seal correctly.
