I have a little annoyance not bad at all just curious. after I have rode around 100 miles if I am running slow at 45 and not giving much fuel at all,it will cough just once in a while like a backfire or just a cough through the carbs....not but 81000 miles. runs just great. if it were a valve I would think it would do it much more often. it just does it when I am almost at a coast. and just 1-3 times a ride. if I give it fuel or keep it in a bind pulling it does not do this. I had timing belts put on before daytona. about 1400 miles on the belts. My first goldwing . it is an 84 1200. I already am in love. thanks for your help. turtle:doh:

If it does it when you back of the throttle, then its probably the air cut valve

in the carb system

I would drain the carbs. Lots of times there can be a small piece of dirt or water that gets picked up mometarily affecting a jet.

If the bikes been sitting for awhile, fuel goes bad in the carbs/tank.

where do you live rocknturtle? I agree with bikgra & cycleman on your problem.

Buy a can of sea foam & put around 1/2 that can into a full tank of fuel. Than, go for a long run & let it work at cleaning out your fuel system.

Every fall or winter when you park your wing, use 2 oz per gallon of gas, fill it up & let it run for a bit to get that sea foam into your carbs. Than shut her down & your gas will stay fresh while it's sleeping!

Iknow what you mean about falling in love with the wing so quickly. It's not the slim, sleek, sporty model you always looked at, but once you take it out first that first long ride .........

I recently bought my first 1500 wing and it would cough at low revsit turned out to be old fuel and a faulty plug. Once i had replaced plug and fuel it now runs fine no coughing

You mentioned in your original post that it coughs at around 45 mph. Are your rpms in the 1900-2400 range? I had a similar situation with my '87 1200. It turned out to be some bad carburetor vacuum from cracked hoses.
