Gasket/Seal and not reving while in gear sometimes?

[Cantfindit]

Hi! I'm new to the GS as I bought mine recently. I've been tinkering with it on my days off and finally got it running and driving but the RPMs will surge sometimes and wont rev while in gear on others. I've narrowed the surging RPMs to a bad intake boot on one of the carbs so ill be buying 4 new ones just in case, along with the little rubber plugs for the pilot jet in the carbs so it'll get enough fuel in the lower range. It has a small leak under the jug/head(the part of the head that holds the valves) and I took it off today to find a pristine gasket and 3(out of 4 I'm assuming) little gaskets/oil seals that look like little black rubber washers. I've looked at partzilla for the part but I've got several options so if anyone knows if this is the right part, please let me know. Also if the surging and not reving while in gear has happened to anyone else, please let me know the fix. Thanks! 1981 Suzuki GS650L

It's the gasket right under the top part of the head underneath the valves. Sadly this site doesn't let me post the large pictures my phone takes so I cant show exactly where. I took the valve cover off and removed the camshafts and chain and then removed the top part of the head and that's where it was leaking from. It was leaking from the front left of the engine and that's where the missing oil seal was supposed to be.

Tom, I found to be what looks like the gasket I'm talking about. This one has only two little rubber seals on the corners. Those are the ones I'm looking for.

I think I finally found the ones I'm looking for, I'll post the link in case anyone else is looking for these fuel/oil seals.

What fun ! That’s the head gasket ....as far as I know new ones come with the oil seals installed in gasket....(there’s oil pressure running up thru each). So you took off head and found those oil seal washers floating around?
As was previously mentioned, you should replace the the base gasket too ,as it will likely leak. A Genuine Suzuki head gasket ain’t cheap by itself....might want to search for a complete Suzuki OEM gasket set ,as you’ll likely need other gaskets.

Got it back together and runs now. I finally found the oil seals, their part number is 11143-06b00. I think I got them from partzilla so they're available. Now I need a place to sync my carbs. If anyone reads this and has a shop in middle Tennessee, leave the name of a reliable shop I can go to in order to get my GS running right. Thanks again!
