81 gold wing 1100 Interstate vacuum advance

Postby Jamesleyone » Fri Sep 30, 2016 3:17 pm



I'm Having trouble with my 81 wing. It will only reach a speed of about 65 mph not good when you are on the highway.
It's like it is bogging out but I believe it has to do with the vacuum advance.
I recently noticed that the hose that travels up towards the fuel tank was not connected so I started searching for where to connect it
with no success. My local Honda dealer would not give me any info on this saying that they are not allowed to work on anything older than
2000. are you serious. I was also told that this hose connects to the cdi box. Any help would be appreciated. I just installed new fuel filter, plugs,
and pulled and cleaned the carbs so no drama in that area. James Ley.

The vacuum line connects to the # 3 carb. Read this. http://www.randakksblog.com/gl1100-bogs ... -throttle/

tube goes from pulse generator to carb #3..but you can plug the tube coming from #3 and see if that helps..the advance isn't much and you don't "need' it to run OK..if the vaccumm isn't working correctly it will blog the bike at high speeds..so plugging it stops that.

I don't feel thats the problem, on my 82 had the same problem. After doing many things ( I too thought) the problem was as you say but it was the slides in the carbs all the time. On top of the carbs are a vacuum operated piston (lack of a better word) . Remove the carbs is best then take off the top cap. Theres a small spring and piston looking thing just lifting up and down if dirt is there you will feel not moving free. Also look at the bore sometimes on the very bottom will have a little ridge there after using small round fill the blowing out good. Install the piston back you will feel the difference, on mine that did it. Has been about six years now runs like new. There is more stuff in the forums here also I think here-- http://www.ngwclub.com/forum/ --- If I was you check up a little before doing but I will say it did the job for me big time. Good luck. If you need more help on the I'm more then happy to talk more about it . Its not hard to do by any means.

Other possibilities include fuel issues, jet and slide issues. Pull the line off the pump's out tube add a tube and put into jar..crank her over see if there is good fuel flow..book says 15 oz. per minute at 3,000 rpm is right..you can do 30 seconds for 7.5 oz....next add a line to the carb line with an alternate fuel source..so you are bypassing the pump and tank..if she runs like that..issue in the pump or filter or tank or petcock..etc. If still bad slides sticking?? or floats set too low or clogged main jets???

3 yellow stator wire plug could be burnt. Wire to Pulse generator could be bad... Check your compression... :D

Perhaps the hose connects to the small plastic box that is attached to the false tank? (underneath). I have no clue as to what it does. Some sort of regulator? Regards, Johnny
