1980 gl 1100 just want to experience its full potential

Postby garydale6 » Wed May 22, 2013 7:15 pm



Hi everyone
Just want to say first of all I love the site and I love motorcycles. I got myself a 1980 gl 1100 standard back in Feb. of this year and I'm trying to get the bugs worked out of it. The guy I got it from said the carbs had been rebuilt but it also had been sitting for a while. So my journey began with changing oil and filter,removing the fuel lines and fuel filter and blowing through them(fuel filter didnt seem to be restricted so I went back with the same one) replaced spark plugs, charged the battery and fired it up. It took a a while to get it to start and when it did it would only idle. Went to parts store and got some stabil and it started to do better. I could rev it up to 3 grand before it started cutting out and quit. So I went back to the parts store and bought some seafoam and this made a tremendous difference. Got the bike legal and started riding and it seemed to improve on every trip. Then out of no where it started spitting and sputtering at 3500 rpm and got worse where it wouldnt pull out of its own tracks unless on an incline and the smell of raw fuel was horrible. Decided to replace plugs and added another can of seafoam to a fresh tank of gas. Its back to running decent but it still sounds like the carbs are loading up it back fires when letting off on the fuel and it just dont have the torque all of the time like I've experienced some of the time. There have been occasions when this machine will really get down and go. I have also noticed alot of pressure built up in the gas tank when I take the lid off and the master fuse has been replaced with a piece of wire around the two screws. Sorry for such a long post. Need help in a bad way. Thanks

Sorry, but this is not the straight answer you're looking for. Was just going to mention after reading your post that you should do the timing belts, they are fairly easy when following the how-to section on the site. Also, might not hurt to throw a fuse between that wire, fried fuses are cheaper than fried bike parts. If you do a search for gas cap you'll see some articles that may relate that pressure issue to performance issues, its a subject I've looked at myself because my new aftermarket gas cap releases pressure. The main issue is if it's sucking in air when opening. Good luck!

Pressure in the tank is normal.Vacuum in the tank is a plugged cap.
My 83 was doggy in the 3k range too.
Get a angle inspection mirror,stick it in the bottom of the Plenum box,start the bike and rap the throttle to 4k a few times.
Look at the slides.Each one should start at the bottom and jump about half way up each time you snap the throttle.
Mine had one stuck down and a second one barely moved.2 seemed OK.
It took a hand cleaning and bench shop back to get them working right.
One last thing.Check your ignition timing.It uses both a mechanical and vacuum advance system.They really need to be working to be able to get the Max out of the engine.
Been there,done that...My 1200 could not match it's acceleration.
While your in the carbs,check the air cutoff valve.They do tend to deteriorate.

+1 on what V said and I'd say clean the gas tank and rebuild/clean the carbs. You may have stuff in your carbs bowls that block jets and then get sucked through or re-floated?? or new stuff from the gas tank coming in. Or stuck float flooding it out intermittently.

Add a 30 amp blade fuse..buy one with eyelets on it and just screw it into the two spots where to old fuse went.
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

Stant 10810 is what you're looking for. I was able to acquire this from my local NAPA. Read it somewhere on this site last year, and now I have been using it trouble free for the past year.
