MISSION STATEMENT

Who is Michael "Mercury" Morse?

Dedicated to the maximum enjoyment of the landmark Japanese twin, the Yamaha XS650.
To share the benefit of my knowledge gained over an 18 year period at the largest Yamaha shop west of the Mississippi, as a factory race mechanic for Rickman, Triumph, and Norton, and having raced these bikes since the early ’70s.
To offer old-time customer service with honesty and integrity.
Good communication is the best insurance you will get only the parts you need to do the job.
My No-Nonsense approach gives you perspective as to the complete picture of a proposed course of action, so that you can make valid choices for your particular way of enjoying the 650.

Stock, restored, chopped, bobbed, racer, cafe’d or Tracker; XS650 is spoken here!
