I ran across a "new" '86 250R motor today and I am trying to figure out what it is worth? The story I was told was that in '86 the local Honda dealer had to destroy 10wheelers. They removed all the motors and gave them to a local high school mechanics class. This one was put away in the closet and never touched again. The seller claims the motor will manually turn over and that it has still has the VIN #s on it.. Is this at all believable and if so, what is it worth?? Thanks
