Solved the problem! I had carb issues and (no I know carbs don't effect steering). As I was saying I had carb issues and ended up rebuilding them. While the bike was down I rechecked the steering head and found the bearing preload was far too tight I backed off the nuts about 1/4 turn. Yesterday after I put the carbs back on I took it for a road burn and had it up to 160km (about 100 mph) and no sway at all, it just sat there rock steady. Going around the curves improved too, it was like it was on rails, were before the bike would try to straighten up while going around a bend.
