The Specials do not share petcocks with the standards. The one for the mating surface on the standard is diamond shaped, IIRC.Marty (in Mississippi)

Do you mean the one to mount it, or the one to seal where the valve goes into the housing?Life is what happens while your planning everything else!

The petcock to tank o-ring for the Standards is not a simple shape

He has a special, and they are just a round o-ring. Not sure on the size though. You have to be sure you get one that's fuel resistant though.1980 XS850SG - Sold

Ah, OK, the Specials have a simple ring, Yamaha still supply them, it'll be about $3.

When I had a special tank I actually used RTV to seal the petcocks on, worked great! (probably wouldn\'t do it again though)Nathan

I have a couple spares I can measure. The ones that come in the kits are not oval they come round.Life is what happens while your planning everything else!

Nate, RTV won't hold up to gasoline. Wile E. P.O., Soooper Genius! used it for the petcocks on Columbo instead of repairing/replacing them and putting in new o-rings.Originally posted by natemoen View Post
Over time the gas seeped out around the petcocks and went under/through the paint. It stripped the paint off the bottom edge of the tank and made a mess that was really hard to clean up, seal and repaint.

O-ring
The "gaskets" between tank and petcock are not O-rings, they are oval's, some with dividers to insure screw/fuel seal. Just buy the right "gasket" for your bike/year
After all, they are cheap/ adv. and gas leaking down on to a hot motor/exaust

That's not an o-ring. It's a flat rubber valve. There is an o-ring that wraps around the lever itself though. If the flat rubber valve is in need of replacement, I would replace ALL the rubber bits in the rebuild kit.Originally posted by ruffrider View Post1980 XS850SG - Sold
