A few questions about reinstalling a carburetor

Post by shevik » Sat Oct 05, 2019 11:32 pm



So I recently purchased an 82 gl1100 that had a pretty sloppy single carb conversion on it. The bike ran terrible so I decided to go buy an OEM carb for the bike at a salvage yard. With the help of the incredible minds of goldwing docs my new-to-me oem carb is cleaned, rebuilt, and bench synced.

The issue is I now have very little idea how to put it on my bike because I didn't take it off myself and because some modifications were made to the various hoses to make them work with a single carb. I could really use some help figuring this out. I've included some pictures. It would be very helpful to me if someone could take a look and give me some analysis, or even include a link to a video or forum post that covers reinstallation.

This hose leads back under the fuel tank somewhere, what is it?

Did you get the air intake box assembly along with the carburetor rack? Exploded view of it here....

The second picture (we'll do that one first) is the crankcase vent tube, it is supposed to connect to the air box (tube #9 & 12).

Gasses, water vapor, general crankcase fumes go into the air box, the vapors go back into the intake and some of the stuff condenses in the air box. The air box collects collects this condensate (nasty mix of water and oil) and it drains out of the air box thru the tube in your first picture (tube #14 & 21) to the collector (part #15). This keeps this nastiness from dripping on the roadway. You are supposed to empty the collector unit (you should be able to see it near the stator) from time to time.

Two fuel filters is kinda overkill... Usually only one, between the petcock and the pump.

Mark, this is exactly what I needed. Thank you so, so much. And yes, I did get the airbox. I guess I just haven't looked at it closely yet :D
