Greetings all, this is more of an informative post detailing my experience with a petcock rebuild kit. I am well aware that I am not the first, nor will I be the last to comment on this subject.
I procured several years back a gs1000 with many problems. One issue I ran into was a leaking petcock.
The style of petcock that was stock for this particular model, this particular year, is of the type seen here (1981, gs1000)

Pardon the obnoxious stamp
There was fuel bypassing the internal piston, whether from a weak spring or worn seal I could not determine. Further, the air-bleed hole was leaking fuel as well. The several problems experienced here led to fuel flowing freely into the carbs at all times, eventually bypassing a stuck float needle and filling the crankcase with fuel.
The first attempted solution was the universally-loathed rebuild kit. My experience with this, sadly, was the one that is common and known to all who have come before me. If anything, I noticed even MORE fuel flowing while at rest.
My ultimate solution was to take a spare petcock, one from the 1982 + series bikes - and one that is available for half the cost of the stock petcock (seen here: http://i.ebayimg.com/00/s/NzY4WDEwMjQ=/$T2eC16hHJIYE9qUcQYgzBQgG2rG,ig~~60_35.JPG) Apparently new restrictions prohibit posting more than one photo per post? Peculiar, but you can see it here.
Anyways - The benefit of using of the these different petcocks is thus: the central chamber through which the fuel flows is perfectly uniform - symmetrical.
First - I used pair of vice-grips to remove the nipple from the original side.
Second - I bored out the other side w/ drill press.
Third - JBWeld Steel-Stik epoxied in the nipple to the other side, and plugged the old hole.
After a couple of hours of curing, I had a like-new, better-than ever petcock for my gs1000! The design on this one is much more simplistic and low-profile, fewer parts, and generally better looking. Hope this helps someone out there dealing with this particular model / style of petcock, if anything to offer a potential alternative solution.
Hopefully I can find the pictures I took of that whole process, if I do I will certainly link them in. Have a great day everyone!
