    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...

  • Returning Visitors

    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.

I finished the world's longest head rebuild, (about a year :oops: ), and just flashed up the old 750 today. Small problem, the gas line tee that goes into 2 and 3 carbs leaks! :roll: There are no o-rings it per say, it looks like the rubber is formed onto the tee. I checked Alpha Sports, (computer is closer than the Suzuki shop), and their part number is 13685-45020, which is "not available." Is there a cheap fix for this, or do I have to darken the doors of the dreaded Suzuki dealer and be told it's "discontinued"? Anyone?
 
You may be able to get one of the brass T's from a different bike and use Herr Barr's o-rings to seal it up. It might take a little searching and/or a knowledgeable parts guy, but its a thought.

Kevin,

Not saying that it WILL work, but try leaving the T there were it is a day or two, if it's not leaking too badly. Have had that happen a few times on some bikes myself when the carbs have been disassembled long enough for the carb-to-carb fittings to dry out.. It almost always solved itself overnight, after the rubberized part slowly swells back up when surrounded with fuel.

I thought of that, but it was leaking enough to not make that an option. Thanks for the suggestion anyway. :-D
 
I think your only options are:

- find a fitting that uses the o-rings - they're pretty rare
- machine one youself - not easy
- try cutting off the sharp corner of the openings on the carbs where the fitting goes in. Then put an o-ring on the fitting (over the rubber sleeve) so that when it is assembled the o-ring is squeezed against the opening in the carb. Several folks have had success with that. Not a good explanation, I realize...these may help:

- Another option is to take the tee off and just soak it (and the sleeve) in gas and hope it swells sufficiently...

Good luck...
 
Thanks, Paul! Looks like Sandy has the fix. I think I'll give that a try. Gotta fix my damn sundeck first though....:evil:

Kevin, I thought I put this in the tips and tricks section but could not find it? Anyway, what you can do is take a sharp Exacto blade and cut the ribbed areas out of the t just like you were trying to free o-rings. You may need to use the blade then to scrape and clean up the area under where those rises where but now you can install o-rings onto the tube. I used some from a carb rebuild kit I bought so I am not sure what exact size to use but most likely some of the o-rings Robert Barr sells would work. Anyway, I did this and if fixed the problem permanently and now if and when they ever wear out I can just install new o-rings. Of course, those carbs are gone and the bike has different carbs now but it held up for years like that. Hope that helps.

Sheer genius, Hoom!
