:waving::waving:Welcome to the Best Goldwing Site on the Internet Ed!:waving::waving:
It's possible you have a defective tire. The wobble at 35-40 is a curse of all Wings, usually only happens when riding with no hands on the bars, usually will stop with just a finger on one grip. Not all Goldwings do it though. It is strange that the problem has lasted from the 1000 all the way to the 1800 especially with the frame change on the post 2000 models. Fork braces don't seem to the the answer, a few get results but most don't seem to. Check your front and rear tires for cupping, that can happen early on with agressive riding, make sure the rear has the proper air pressure too. I experimented a few days ago by reducing the air pressure in my rear tire and the wobble appeared again, brought the pressure back up to normal and it went away so at least in the 1500 the rear tire pressure can affect the wobble.
The only suggestion I think might help your problem would be to try a different brand tire on the front and see what happens.
