1980 GS550L petcock conversion

[DougMarshall]

I just bought 1980 GS550L that's been sitting for 2 years in garage. First issue off the bat the gas leaking through old o-ring from tank to petcock and ordered one but before I try getting this stock petcock going, I have seen the name "dreaded" petcock for these 1980's a few times now and was wondering if I should or if its even possible to change this petcock out for something that's not so "dreaded"?

If you got the dreaded 1980 petcock, go the easy route and get new one from this florida guy $50- probably will outlast you, once you understand how it works

When I had my '80 750, I put on a Pingel and an adapter plate. It worked great but was an incredibly tight fit. The nice thing was that it was a high quality part and it had a 'reserve' but they've gotten pretty expensive these days. If you want to get an after market vacuum petcock, I'd suggest you buy it on Ebay.....they're cheaper, made in Japan and are probably pretty high quality. (The one Tom mentioned is probably the same thing, but for more money.)

There isn't much out there that swaps straight in. Things like an XS650 unit has the same spacing but when you read of the Yam guys swapping these out it seems rather pointless.

As said above, just get a new replacement part. That's what I did after trying to fix the one fitted to my bike and and suffering a flooded engine after the failure of a second unit I reconditioned.

I just used an after market universal petcock and plate just measure your holes and see which plate you need. Works fine on my Gs750 just cap you vacuum port on the carb. $38.00 for both.

I wouldn't buy anything from him.

I bought a petcock from him 5 years ago, fast free ship. Unit is decent quality probably made in same Japan factory as a suzuki oem. I have no idea about other stuff that he offers.

FYI the hole spacing is 50mm.
