SOOO, it's either try my luck with one of the Z-1 aftermarkets, or go with a '78 OEM from Bike Bandit for twice the price, over $80 I believe. Did I mention ??

I've use several of the Z1 (K&L) aftermarket petcocks with no issues. One flavor has a higher fuel tube which results in having to switch to reserve earlier. I would not recommend that one for an "L" tank, as you'll be switching to reserve fairly quickly...

I think that's all the endorsement I need. I hate to give up the stock item, but I was thinking, every time the petcock needs a new part I'm going to buy a new one? tah HECK with that!

I got a kit from CarbKitCapitol.com for my 79 GS1000 L

I'm installing it today.. I'll post how it goes..

Some they fit, some they don't. Too bad they don't tell you which ones.

While my bike is apart I took the petcock apart to check it out, because I notice it's been getting a little 'weepy' (not to mention floats were starting to stick). The problem turned out to be the O ring on the diaphragm, it wasn't sealing properly. I've read about the rebuild kits but I already had a spare diaphragm that came with the bike, and was in good shape - so I put it in, hey it couldn't hurt to try. Well the think really oozes gas now, not full volume but a LOT. After some studying I conclude that the metal post that the O ring mounts on is not long enough to properly seat the O ring in the petcock, thus letting gas enter from the tank at all times. No matter what I do the thing will not seat, yet when I install the diaphragm without the nylon spacer it DOES seat. My theory is that these K&L kits are sold as a one size fits all, but in reality one size does NOT fit all. These people really have no business being in business. I bet I could take the O ring off and put it on my old diaphragm, which probably was okay, but I was stupid and threw it away . SOOO, it's either try my luck with one of the Z-1 aftermarkets, or go with a '78 OEM from Bike Bandit for twice the price, over $80 I believe. Did I mention ??

If you buy ONE Pingel petcock, it will last the life of your bike! Simple as that. Or, you can keep buying stock diaphram petcocks that will continue to fail. I use Pingels for a reason. Ray.

Got to disagree with you Ray. Those poxy O-rings wear out too fast and the blo*dy things leak as if they were run by BP. The OEM ones do wear out but buying a new one every 20 years or so ain't bad.

Or replace the things with the old fashioned cork seal type. They fail a bit quicker but making a new cork seal every now and then for pennys (or use the cork out of an empty wine bottle for nothing) is hard to beat.
