I have a 1989 1500, and the carbs are not right, either.1997 Goldwing, with speed between 30 & 50 it's like the carbs or loading up. The onlY thing I have done to try and fix it , new plugs. As long as you are give it gas, runs great, and idles good
I can't choke it to start it - even cold - and all I have heard is I need to replace all the hoses under and between the carbs
I do have a shop manual that lists all the different sizes of hoses, and it has my head spinning.
My manual is for 1994 and up, if you would like a copy.
