    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Fuel joint

Hi all I have a gs750 1980 UK model with vm carbs I am leaking at the fuel joint where
the tee enters the carbs. There appears to be a kind of sleeve as opposed to o rings.
All lists point to o rings, but there are no grooves for the o rings to sit in? Can any one help?
Cheers Rob
 
Recently had the chance to try out putting o-rings on mine and it works quite well. The ones for mine where size -011, they're a standardized 11mm ring and the local auto parts store had them in stock.
 
There are various aftermarket metal fuel Tee's on the market. Ebay should provide some enlightenment.
 
replace all of them with aluminum ones with orings. My opinion is these dipped up pieces of sciit suzuki came up with is possibly the worst fuel management idea ever
 
I don't know about the Z1 Tee for the GS750 but their Tee for the KZ1000's have O-rings that are too fat. I had to swap them out for something thinner. That's one of the reasons I decided to make my own in subsequent builds (since I have a lathe.)

Yeah, they're too fat for the 750 too, The Robert Barr kit fixed that though.
 
I've had success in carrrrrrrrrrreeeeeffffuulllllyyyy cutting out the raised "o-ring-ish" bits of the crappy rubber coating with an X-Acto knife, then installing o-rings in the resulting grooves.

You might also be able to soak them in a mixture containing methyl salicylate (wintergreen oil) to swell and soften the rubber a bit. I've done this with other rubber parts and had some success.




But honestly, I'd just replace the damn things with proper aluminum or brass equivalents with o-rings and be done with it. (I don't know exactly which to recommend for your particular carbs.) Both the above re-use tactics bear some risk of failure and repeating disassembly/assembly, and really aren't worth the potential waste of time. Not to mention dumping gas on your engine and tire kinda sucks.
