Welcome and make yourself at home here. There are several others here, including me, with older models. You will find that we are family of sorts here so make yourself at home and use the search window above. Documents are not stored here but many common problems or topics have been discussed. You won't even have to wait for a response as many questions have already been answered.
Why don't you fill in a little info in your signature so when you ask a question, all can see what bike, year etc. you are asking about.
I highly recommend the GWRRA groups (Goldwing Road Riders Association) to find folks who ride wings in your area. When you attend chapter meetings you will find friendly folks that ride the same motorcycle you do, and they know their motorcycle.
Not many people like going down the road I have. If I think it could play up, it gets replaced. I was on this forum for months before I
brought a bike and learnt a lot. This is what I have done.
Replaced front and rear tires. The rubber had gone hard. A new battery.
Fork seal was leaking, repaced seals. Then kicked myself for being a cheap skate. They still leaked. Forks rechromed and new seals. While the front was clear [easier to work on] replace the belts.
Cleaned up the 30amp fuse next to the battery.
Pulled the motor and replaced stator, starter, clutch. Replaced all fluids.
Now it is the 11th. hour in that next week we are leaving for a 2500 mile trip and the motor is in place but not in. Got to go or I will not be going next week. Eric
The only thing I'm aware of, that has been a constant problem with the 1200s, is the stator. If the wires connecting it have been soldered, you will be less likely to have a problem. Some folks just keep the connector clean and have had good luck with them.
