Hi, does someone know what number "O" ring is used for the oil filler cap on a 1980 gs850g? Thanks Ted

Suzuki's number is 09280-32005.
Not sure if one from the auto parts or plumbing shop would stand up to the heat, so choose carefully.
Flatout has that o-ring for the exhorbitant amount of 99 cents, your dealer might charge a little more, but probably won't charge shipping.
(Click on the link, select CRANKCASE COVER, then look at item #8.)

Ditto on the heat issue. Look for Viton? or some other fluorocarbon (FKM). If you want, measure the groove dimensions, and I'll look it up in my charts. I'd go measure mine, but the battery is dead in my calipers.
More than you ever wanted to know about o-rings:

I'd post a link to Parker's o-ring handbook too, but I can't find it on their web page. Impenetrable garbage.
I have boldy ventured forth into my garage and verified that a #125 o-ring will fit the standard GS oil cap (30mm threads, o-ring slot ID of 32mm).
It takes just a tiny bit of persuasion to go into the slot -- it's a weeeeeeee tiny bit too large in diameter at first, but you can push it in just fine and it stays in place.
The #125 o-rings I had were Viton (Doesn't everyone keep a stock of Viton o-rings? That's normal, isn't it?), but for this application, you probably don't really need Viton -- the clutch cover doesn't get that hot.
I'd throw in a #125 o-ring from the hardware store and ride happy. Order a new one from Suzuki the next time you order up a batch of parts. Or ask for the part number next time you're at the dealer -- a lot of generic seals, o-rings, and such are kept as stock shop supplies.
In case you were wondering, #125 Viton o-rings also work great for the intake boots on a 1979 GS850 (32mm ID o-ring). #128 fits 80-83 GS850 (38mm), and #129 fits a whole bunch of models (40mm). \\

Thanks for the number size. I don't think the clutch cover gets that hot to influence the properties of the o ring, so I'II just pick one up at the local industrial supplier. If you want just one or two they hand them out for free. Ted
You're probably right but keep your eye on it for awhile to make sure it doesn't get "gummy".:-s

Nitrile rubber should be fine in that application. Viton (fluorocarbon) is overkill. But when your major expense is driving to get it, or S&H, spending the few extra cents makes sense.
