    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.

Carb leak

O.k. I've been working out some of the gremlins living in my bike and I have one that is keeping me from riding now. I have a fuel leak that is coming from between carbs 1 and 2. It is not coming from the overflow but rather looks like it is coming from the transfer tube. Kinda hard to see and it only leaks while running. My question is, (and I haven't been able to see it on carb breakdown) are there o-rings on the transfer tubes? I would like to source them before tearing them apart if so. If there aren't o-rings, how do I seal them? Thanks guys.

Yes there are O-Rings there. You can get a complete O-Ring set from http://www.cycleorings.com/ he uses this forum very often as well. I used him and so didnt many others.
 
If you still have the original transfer tubes, they are covered with a rubbery vinyl that covers the o-rings and makes them look like bumps on the tube. I have seen some success by wrapping a few turns of Teflon tape around the o-ring area and re-inserting the tube. Note that this is only a stop-gap measure that will work until you get your new o-rings, but it will keep you riding. 8-[

On my 650 (which was the last bank I fully dismantled) the middle tube was a molded plastic type of material (delrin? nylon?). The outside tubes were metal with o-rings. Never had trouble with the molded one, but Robert Barr's kit fixed the leaky outside tubes.
 
O.K. while I am at it, does the '83 16 valve have o-rings on the intake?
