New to the forum. picked up a 78 cb550 a couple months but just finally had time to start doing some work. The bike runs but poorly at best, just carb issues though. I have cleaned the carbs got all the passages clean I believe finally and set the floats and got them to stop leaking. So I'm hoping it will idle much smoother and I can vacuum sync it. I also cleaned the tank and bought some new euro style bars for her.
