    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.

Stupid question.

I have a 1981 gs1000GL. Could someone please tell me the functions of each of the 3 hoses coming from the gas tank. 2 on the right side (at the petcock), I would imagine that these 2 are fuel supply and vacuum. But what is the hose on the right side of the tank for?
 
It's an overflow line in case the plate the float arm is attached to starts leaking. Keeps the fuel from ended up on a hot motor.

Ditto. It should run down between carbs 3 & 4 and end up below the engine/transmission (but hopefully not right infront of the rear wheel).

You must have edited something. I did not see the 'stupid question'. :-k

If you have a genuine interest in learing about your bike, you will either have to examine the bike until it becomes clear or ask a question of somebody that might have been there, done that before.

You may get a couple of stupid replies or even some half-

Oh, yeah, Billy Ricks has the right answer for you.

Now, I have a question for you. You made this statement:

How did you get your petcock on the RIGHT side? Since you are learning about your bike, it will also help to learn that left/right is always referenced when you are sitting on the bike, ready to ride. The cylinders are numbered left to right, too, so #1 is under your clutch hand, #4 is under your throttle hand. Keeping this little bit straight will help you as you ask more questions.

Everyone starts somewhere. There are actually some helpful old geezers on here who are happy to help with anything. There are some boneheads too but that's just the law of averages. Generally it's a good forum.

If you're really not sure about a question feel free to send a private message. :)
 
ok, i followed the hose on the right (my "non-petcock" right and it goes to the vent connection between 1 and 2 carbs. Is this bad. Should i mention that i cant get the bike to fire up. It has spark and will crank fine. i get a hint when i squirted a shot of starting fluid in Cyl 1. This wouldn't have anything to do with it ....would it?
 
First of all,

PUT THE STARTING FLUID AWAY. :eek:

That stuff can do nasty stuff if used incorrectly and it's way too easy to use it incorrectly.

List of hoses:
Larger hose from petcock goes to 'T' between carbs 2 and 3
Smaller hose from petcock goes to fitting on carb 2
Hose from 'T' between 1 and 2 is a vent, it goes back, over the airbox and connects to nothing.
Hose from 'T' between 3 and 4 is a vent, it goes back, over the airbox and connects to nothing.
Hose from fuel level sensor (under side of the tank) goes back, along the frame, down behind the engine, just in case the sender leaks.
