Intake vacuum line attachment...what attach to?

[tsandvik]

Down to the last stages of rebuild of 90 GL1500 Aspencade rebuild. There is an attachment point at the top of the right intake manifold the points forward. Up at top by where the carbs attach. Question is where does this connect to? By the looks of the vacuum diagrams (which do look like a bowl of spaghetti) it goes back over to the left intake with a 3 way in route. Is this correct? I have put in a new engine and this is one of the lines I kind of lost track of and does not show up on any of the pictures I took.

Replaced all vacuum lines while bike was totally stripped down and had access. Knew there was a lot of vacuum lines in a Wing but I swear I have replaced about 47 miles of tubing.

Here is a vacuum diagram I picked up somewhere along the way. It has red lines showing how the hoses are connected. This might help you find out where your hose connects.

Good stuff - downloaded/saved it!

Thank you so much. This answers what I thought was going on. It is not easy keeping track of all the lines when you do a complete engine swap. Line get lost and mixed up when transfering over. Almost impossible to get any pictures that make sense.

Get yourself one of these, it has saved me hours over the years. I did a mazda rx7 once. If you think the goldwing has a lot of vacuum lines you should try a rotary

I've had a Brother P-Touch labeler that I've used for MANY years that works just like that. I'd like one like this that you can connect to your computer:

However....the 15+ year old one I have still works great, so I can't really justify it.

The only problem with using them for vacuum lines is that the labels are thermal transfer: the labeler "writes" on the labels by applying heat.

If you put the labels anywhere that they are exposed to heat (or sunlight, for that matter) - such as around a vacuum line on top of an engine - they will quickly fade away and anything printed on them will disappear.
