    Differences in Opti 200 and Opti 225

    In a 1999 Optimax 200 and a 1999 Optimax 225, what are the major differences? Both are 3L motors and covered in the same service manuals. Could someone enlighten me on what the differences are. I know they use different computers. What else is it?

    Different block (same casting, but different porting in the sleeves), and different cyl. heads.
