Carb Compatability

Postby portugeezer » Fri Nov 08, 2013 7:09 pm



So the season is over here in Northern Illinois. I have my bikes parked. Fork seals need to be replaced on my Gl1000. I have been wondering about something. My 1983 Aspencade that burned in the fire was a lot faster than my GL1000. I'm told by many Goldwing riders that the carbs are the difference. I have also heard the GL1100 carbs will fit a GL1000. Is that true? Any mods need to be done? I also got to ride a friends 1979 GL1000 and that seemed faster than mine. Again it's supposed to be a carb thing. Near the end of the season my bike had also become difficult to start in the mornings. I plan to reset my valves but suspect something going on with the carbs as well. Any advice?

Hi,

I keep seeing your question hanging out there with '0' responses and thought I'd suggest something. Mike Nixon is a carb guru. (You probably know of him.) If anyone can give you a 'yes' or 'no' on this, it would be him. Although he's in the business of carb. restoration and one can't expect him to work for free, I've found that he's very approachable and willing to give a bit of free advice from time to time. His Web site is: http://www.goldwingcarbs.com/. Another contact would be Pistol Pete. His Web site is: http://www.oldwings.com/.

Your 76 should run as well or better than the 83 or 79. The cams are "hotter" on the 76 and the carbs are designed to function with the cams on each year bike. That said there is so little difference performance wise that you might be hard pressed to tell the differences with equally "tuned" bikes . If you can tell the difference in your 76 compared to the 83 and the 79 then I would suggest that you have a tuning problem. Could be carbs or ignition or even compression.

The 1100 carbs will work with the 76 but not as well as a set of 76 carbs. (If they are clean and functioning properly.)

I didn't answer yesterday as I'm not sure what was done to mine as far as jetting goes,but my 75 had 1100 carbs on it when I got it.There is a hose on the right rear carb for the vacuum advance that needs to be plugged off,as the 1000 doesn't use it.Sounds like you'd be better off with the originals rebuilt though.
If I'da known it would last this long,I'da taken better care of it.

Then I think my plan will be to rebuild the carbs. I got the bike about 3 years ago. Cleaned the jets reset the floats and synced the carbs. I replaced the belts the water and fuel pump the thermostat and the cables. I then rode it to Colorado. Since the fire it seems to run a bit worse. I have ridden three seasons without doing any other adjustments. The points had been switched to electronic before I got the bike. So I guess my offseason plan of attack is the fork seals and the Randaaks carb kit

I just worked with a buddy and made an aluminum intake and used a single auto carb. Easy to tune, runs great. We just couldn't get the 78 carb set up to work, even after rebuild.
