'81 GS650G petcock application puzzler

[hank2]

I read Admiral Beez's thread on petcock troubles below. That got me checking on availability if or when I need one. ( no trouble right now). Partzilla shows "not available" for a OEM vacuum petcock for my GS650 G for "X" model. I believe that's '81. They do have availability for the "Z" model. Is the "Z" model an '82? One of the one model year deals on a model with it's own unique features, is that the '81 does not have a gas gauge. I don't know why that would matter? Checking Z1, they have a few petcocks left that they apply to almost all the GS's. Same with the George fix shop store link that someone had posted.

Anyone been there with a GS650G or have thoughts? Maybe different pickup heights?

They use the same petcock, BUT there are two styles....most common is the one you mentioned off Georgefix site....used on lots of models... There is another style that has less reserve capacity than standard. I bought this style for my L tank . With the G tank , I'd get the other for its extra reserve. The Georgefix site lists both.

Thanks, tom203 and Redman!

In answer to your other question, it was the 1980 model year that had the "dreaded" petcock.

Fortunately, it did not affect the non-L shafties.
