First of all I am a new Goldwing owner and am enjoying the challenge of trying to restor this wonderful bike back to health. I purchased a 1978 GL 1000 that had not been run in a couple years. I have run sea foam through the carbs and got the bike running alot better but feel that I may need to rebuild the carbs to resolve the issues I am having. Here is a brief description of what is happening. I sinked the carbs per the service manual and tried to set the adjustment screws like the manual says by turning the screws in till the motor looses 100 rpm then backing them out 3/4 of a turn but carbs 2 and 4 will not drop rpms even with the screws turned all the way in so i only turned them out 3/4 from bottom. At this setting the bike seems to be running rich and pops through the right exhaust at idle. Also when you are riding at speed and let off the throttle it pops through the exaust. To try to resolve the issue I have tuned all 4 screws in aprox. 1/2 a turn and still have good power and on trips am getting 41 mpg but it doesnt seem to run as smooth at idle. Any suggestions would be appreciated.

Sounds to me like you may need to rebuild the carbs, but there is more to try first. I have hear good results from using Berryman B-12 Chemtool® Carburetor, Fuel System and Injector Cleaner. Some say it works much better than SeaFoam but no personal experience myself.
