    So what do these Protec heads fit ?

    I bought this head at a local service shop that was going out of business. It was in the original box but No part number anywhere. It does have instructions and someone wrote on the box yamaha 650. when I go to Protec's website this head doesn't look anything like the one they have pictured so thus why I'm posting it up here. The gasket was in the box too and looks to be the right one but I can't verify

    Anyone know what it fits ? I'm getting ready to post it up on Ebay so............... it's NOS

    Looks like a 650 cc or 701 cc head . You could go to there are a lot of super jets that use those motors in them they have a classifieds section on there to sell parts like u got. (61X) Head gasket is for a 701 cc motor. Tommy Jordan
