i have a 77 gl1000 it runs like it is getting to much fuel and it cant burn it fast enough.it idols fine most of the time but when im doing a stedy speed it just dont feel right it is hard to explain. when i pull the choke in it smooths out for a second then its back to not running right. if i pull the choke in and out constantly is runs alright and i can only get it up to 93 mph once im at 93 it has a slite surge high and low it keeps going high low high low and so on im guessing maybe the wireing or the coils or something the carb is sparkling clean. just seems like there isnt enough spark to get the job done sorry for the long story any help would be appreciated
It could also be that you have an intermittent air leak. It could be that some of the rubber seals in the carbs is loosing seal. My guess is that you can probably get a temp fix out of running cleaner thru the carbs
but ultimately you are going to need to rebuild them. That should fix the problem long term. New Rubber and reset everything to defaults should do it best.
And if case you don't know, many owners put GL1100 carbs on 1000s because they are a direct replacement and are newer and more stable carb system. So unless you are a stickler for pure stock 1000 parts, upgrade.
Try some Seafoam added to your gas before you take it apart. On real hot days, mine wants to idle fast and this Seafoam seems to help. It has a great reputation and is also known to be gentle on seals.
Im going to guess your running points in that bike. If you are, check the shaft bushings for side to side play. This could be fluctuating your dwell & gap which might cause this too.
What you're describing is probably a fuel supply problem. Not enough fuel getting to all or even one carb. Same symptoms will occur with a vacuum leak. If you pull the plugs I'll bet all or one of them is burning too lean (white instead of tan). If it were an electrical problem the choke shouldn't effect it the way you describe. When you say the carbs are sparkling clean, what do you base this on? Have you had them apart to rebuild or what?
