I thought the Triumph Adapters or Adapters from Ma's Cycle were the only ones that would work on a BA or SM. The metric adapters for the Jap bikes will not work. What kind of adapter are you using? I hate the factory mirrows as they are just stems !!!!!!! Also its hard for me to pay $18.55 per adapter plus shipping. You wind up with about $45.00 in just two adapters.
