Hey Thanks for all the replies. Scotty, we won't mind if they laugh to hard as long as our bikes aren't running out of gas at full throttle. :lol:
OK, I did some measuring on my spare 1980 GS550L gas tank which is lying in my garage. On this particualr petcock, the holes are 50mm apart.
Some bikes are 44mm like yours is Scotty, which is the difference in Pingle part numbers.
I just got off the phone with Russ, the order guy at Pingle in Wisconsin who by the way is very nice and helpful. The Pingle petcock part number that our bikes use is either a 6211-AH which is the aluminum one, or the 6211-CR which is the chrome one. I chose the 6211-CR (chrome) because
Russ told me that the chrome cock had brass internals and was more durable and would hold up better, $10 dollars more at $72.30.
Here is the deal on the adapter plates. The A1902C ($11.35) is what you need if your bolt holes are 50mm apart like mine are. The A1702C is the part number if your bolts are at 44mm c to c. So I am told by Russ.
Russ also told me that the petcocks are fully rebuildable and that Pingle likes for you to ship the petcock back to them should you need service. If they can't rebuild it, they will replace it. I'm not sure about the cost, if any on that. Russ said that I will probably have to enlarge the hole where the pipe and screen extends up into the tank and if I need to cut the pipe off and trim the screen, I can.
He shipped it out today so, I'll let you know the results when I switch the valve on, fire it up and go hold it wide open for awhile to see how well it flows. :wink:
Cheers,
Blake
