I just read a super old post on the forums about the 'pingel' and this link:
w.streetfighters-usa.com/pingel_power_flo.htm
I believe it's dead, is the 1702c the one that will work ?
thanks guys

for what it's worth, the part number on my stock pet cock: 442 09 50

Hi Mr. zedman,

I just wanted to greet you properly. Yes, you can use a manual Pingel petcock. Just block the vacuum port from the carb and you may need an adapter plate for proper fitment. However, if you forget to turn off the petcock you will fill the crankcase with gasoline. That is not a good thing. Since the petcock rebuild kits are not reliable an OEM or OEM-style part is usually best. Now here's your "mega-welcome".

If you are here you probably have a 30 year old motorcycle that needs about 20 years worth of maintenance. You'll find all kinds of helpful tips, procedures, manuals, diagrams, "how-to" guides, etc, in the links below. Let's get started.

My '79 GS1000 for some reason had the '80 style petcock that has no lever on it, it must be turned with a screw driver. I tried a different style petcock that was specified for a '79 and it didn't fit. Maybe my tank is off an '80, I don't know. Anyway, I replaced it with the same style from oldbikebarn, I want to say it was like $60 shipped.

As you said most likely an '80 tank and petcock.

If you wait long enough and look hard enough, you'll find used ones on E-bay. I found 3 over a 9 month period, picking them up for about $25 or so.
But........ I still had to work on them to keep them from leaking.

Here is a photo of the external air mixture screw with some of the white powder resisdue when the srcrew is removed their will be more powder almost like pipe tape have to remove the jets to remove the screw and clean if read this correctly

I will also psot photos of the tank Pingle and petcock later on

Shouldint the petcock not allow fuel to flow into the cylinders if the floats are closed is thier any way around the problem?

All that white stuff is on the screw is the paint they used to seal it, or show that it was in this position. We're not supposed to mess with those screws as they are set forever at the factory (yeah, right!) Do you see that little indent on the carb next to the screw. That's factory imprinted to mark the original location of the screw slot (really!). It's usually about 1.5 turns out. Feel better now.
Should you mess with those screws, you got to get all that white paint out of there, once you see what they're set at.
Get this, and this is very, very, very important. When you screw in those screws, do not over do it, lightly seated. They have long tips that break off in holes you don't ever have to want to get to, nevermind try to get the broken tip out.
Remember, ever so lightly seated!

I'll probably order the PINGEL (I'm in the habit of turning fuel flow off anyways --lawn mowers, etc) then get a rebuild kit for my stock one for sh*ts and giggles !
Thanks all

Thank you for the welcome, I have seen your welcome post and have been on your site extensively thus far. I really do appreciate the time and effort you gents put into these sites, it sure makes owning these unique old beasts a lot easier !

Searching and reading more on this site, and looking at some pics, my petcock looks like a 78 gs1000e (two tiered filter). And I seem to recall the PO stating he swapped the gas tank from a 78.
I'm guessing bolt hole spacing is the same for 79 and I shan't worrry ?

[OldVet66]

'78 and '79 petcock were the same. The '78 had a small inset running down the center of each side of the tank (the black ones had a white stripe "skunk"). The '79 had smooth sides. The '80 looked identical to the '79 but had the lever-less petcock and even spaced holes from the screen where '78 and '79 were offset.

[zedman]

My tank has the 'skunk' stripes and small insets, she is a 78 tank.
I finally decided to pull my head out of my arse and figure this out. I took my digital caliper out, bolt hole center spacing is 44mm just like everyone else (duh).
Problem solved, thanks all !

I have a 79 1000L also and it had the same petcock. apparently it was made specifically for the 79 L. at least that's what I'm going with. I got one just like it from z1enterprises.com and love it. @zedman, give z1 a call I'm sure they could get you what you need.

[zedman]

Thanks for the info, I just ordered my pingel and adaptor plate ! I'll post how it all turns out when I get her done.
Thanks all. Cheers.
