I´m in process of buying a silver 2003 400 Burgman with about 700 miles on it. The road test went very well. The idle could improve, but I think I can take care of this with fresh gasoline and more use than it has had. The seller recommends that I add some gas stabilizer to help. It comes with a service manual, but not an owner´s manual. I´m moving up from a 2 stroke 50cc Kymco, but have my motorcyle license and had a 250 cc Aprilia last year which I did not like. Any help or recommendations would be appreciated.
