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 a 18 year period at the largest Yamaha shop west of the Mississippi, as a factory race mechanic for Rickman, Triumph & Norton, and having raced these bikes over a period extending back to 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.
