1980 lever less petcock diagram ?

[suzukiSam]

does anyone know where i can find a diagram (similar to this one) for 1 1980 GS1100E petcock ? (the one that doesn't have the level on it).. I need to know if the order of parts/re-build between the main housing, and the final plate is.. 1. main plate (attached to tank), 2. then rubber diaphram with o-ring down, then 3. the spring, and then the final plate. (four screws)

The o-ring goes up into the tank.

Don't waste your time trying to rebuild that style petcock. For one thing, they are the cheapest off all the GS petcocks, and secondly, there is a built in check valve that often fails, and is not serviceable.

Did you introduce yourself and your bike in the GS OWNERS thread? If not definately do so, as you will get a welcome message with tons of info on your bike and all GS related repair/mainteneace, including an owners and service manual for your bike. ALso go to quick links above in the blue bar and choose "edit signiture" from the drop down menu and add your bike, year/model so we always know what bike you are talking about and you dont always have to type it in.
I just bought the 45$ petcock Nessism showed in the first e bay ad....looks like a nice unit and I dont have to worry about a malfunctioning unit. go for it!

ah, so that's what all that black goo was - old rubber from an inaccessible check valve. thank's for the links to the replacement options. saves me some time searching the weeb.

cheers.
