    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.

Hoes...Er...HOSE, What size hose?

Um, what size hose do you need to connect the petcock up to the carbs.

I want to install an inline shutoff valve so I went out and got some hose that was clear and it was too small to go over the fuel inlet nipple on the carb. I even tried heating and streching it but the hose tore up instead.
Then after trying again heating streching and letting it cool the hose apparently was too soft to push onto the nipple and it kept buckling.
Went to use the needle nose pliers to pull it on and it tore again.
I believe the heat compromises the strength of that particular hose.

Anyhow it was too small. So what is the right size?
Bike is a 1981 GS750L with 34mm CV carbs.

I use 5/16" for the fuel and 3/16" for the vacuum. I don't know where the heck you'd find metric line...my dealer doesn't either. Also, I would keep away from the acquarium line, I used to replace it every year when I had a snowmobile. It gets really hard and even uglier with age.

My 79 750E uses 5/16" for the fuel and 1/4" for the vacuum line.

Awesome, Thanks guys. I will go buy some 5/16th fuel line hose today at lunch.
One more question...
The 80's+ GS bikes come with CDI ignition right?
Just asking cause I've bid on a set of Coils on EBAY that say they're for CDI ignition. Mine's a 81'GS750L so I think I'm safe.


Thank you,
