Hi gents, I seem to have a problem w/ my 83 GL1100. After warm up and cruising for about 25 miles my bike starts to loose any zoom over 4k. With a load on it, it starts to sputter and loose power but if I keep it at about 4K it seems to still cruise pretty good as long as I donĀ“t try to goose it. It has about 28K miles, I did normal service, Plugs, carbs, Oil Etc. Any Suggestions would be appreciated. Be Safe & Thanks, JJisme
