leaking petcocks

[dontlikeoc]

DGXSER,

Using a hole punch makes the whole cut out process so much easier. You are saving my aXX so many times. Thank you again.

Larry, sorry if I was critical of you personally, not intended to be. Just the nit picky engineer in me coming out.

Dontlikeoc, I did not find those gaskets anywhere. I happen to have a spare sheet of gasket material on hand so I just cut them out. REALLY easy to do, just use a standard hole punch to poke some holes in the gasket material, then cut out roughly shaped pieces, put them on the screws and trim off. I used two layers of gasket material on each screw.

Semantics?

You know Larry, if for some reason you need to pull the tank off, say to work on something underneath it, that little octy device does not do crap to stop fuel from flowing out the petcocks when you pull the gas lines off them.

Brownbear1000 reported that his petcocks were "leaking" but didn't provide the details of how he came to that conclusion. Not known if it was due to seeing gas flow out of the airbox or seeing the fuel seep out around the petcock levers.

Maybe I might have said, "The automatic fuel shut-off to the carbs is done by the vacuum diaphragm/shut-off valve."

I've always clamped the fuel hoses before removing them as well.

Sorry about any confusion...

Please excuse me for a sidetrack.

Mine was probably a rare case but, afrer replacing O-rings with the petcock overhaul kit and oblong O-rings at the base of the petcocks, the right side petcock is still leaking gas. The only reason I can think of is the paper gasket around the screw at the base of the petcock.

I just have found out that those gaskets are no longer available...No luck at Autozone or Home Depot(plumming). Is my only choice cutting out from a gasket sheet? Did anybody find a slap on fit of readily available gasket?

I just happened to rebuild my petcocks and the octy valve from my special last night and did another photodocumentary of it. It is pretty self explanatory really. I did not get a chance to download th epics and do a write up yet though. Had to drive halfway across the US today. Sitting in a hotel in Rockford Ill.

And I have bought two sets of th petcock repair kits form Georgefix. Good kits and he is quick on shipping and fair on price. He does know his doodoo about the XS11 as well.

Here's another option:

I had only one original petcock when I got my bike. Had to replace them both with aftermarket units. Not exactly pleased with the clearance issues.

For the record, if you have the original petcocks/fuel system then the fuel shut-off is done by means of the vacuum operated shut-off valve/diaphragm (Octopus...) But if you say your petcocks are leaking then I guess we'll have to believe you...

I use georgefix on ebay to get those rebuild kits. fast Cheap shipping and he knows his stuff. Very easy to do once you see the kit it is pretty much self explanatory. You may have to recurve the spring a bit and maybe polish the end of the diverter, but not much to them.

The petcocks on my xs1100 special are leaking when i turn them off.
How can i fix them?
and where can I get the repair parts?
