HELP!!! routing air, fuel, and vacuum lines??

Postby harkgold » Sun Jan 22, 2012 7:09 pm



I'm in the process of rebuilding the carbs on my '84 GL1200 Interstate.

All of the carbs have been removed from the air chamber assembly, and I removed the reed valve chamber from the underside of the air chamber so I could check and clean the choke linkage. When I removed the reed valve chamber I discovered to my horror that there are four vacuum hoses of various lengths all taped together and just laying loose under the reed chamber. None of these are connected to anything and I have no idea how these are connected and routed.

I have studied my Haynes, Clymers, and Shop service manuals and cannot for the life of me find any kind of schematic that clearly indicates how all these are to be connected.

The drawings and photos that I do see of air, fuel, and vacuum lines all show the reed valve chamber in place so I can't see how any of these lines are routed or connected under the reed box.

I'm certain fellow Gold Wingers have encountered this situation before. Can anyone direct me to a good drawing or diagram?

Thanks again for your wisdom!

Does this help with the routing?

Yes, this does help Seabee.

I see that there are actually no hoses routed under the the reed chamber. They are all outside and routed around it. I guess I just assumed they were supposed to be routed under the reed chamber simply because the prior owner stuffed them under there.

One further question Seabee: at the bottom of the lower photograph I'm seeing a brass nipple on the Slow Air Cut-Off Valve that does not have a hose on it. I'm wondering where it goes. I can't really tell from the drawing.

Thanks,

Harkgold

Goes over to the nipple or fitting on the back side of #2. You can see it to the left sticking out. Go to my photos and you'll also see. Hope this helps.
Enjoy the ride. They are all good, just some better than others.

I'll have to check my other pics on my laptop to see if I have another view of the carbs. I can't acess them from work.

Yep! I see it in your photo. It's the black plastic "T" nipple peeking out from under the metal fuel coupler near carb #2.

Thanks for the clarification!

There should be a diagram on the side of your gas tank. Remove right side cover it should be right there. if not look on the inter for Vacuum line diagram for your bike.

CORRECTION! Sorry to dig up an old post but the above photo is incorrect. If you compare it to the diagram you'll see the hose Seabee_ connected from the t-fitting should not go to the brass fitting on #4 carb, but to #4 intake manifold brass fitting.
The brass fitting at the base of #4 carb goes up to the t-fitting on the ignition module under the false tank.
