I recently bought a 1977 yamaha dirtbike but it did not come with a title and part of the identification sticker on the front by the forks is missing. Does anyone know how i could figure out what size motor it has. It has a speedomiter and 6 gears thats pretty all i know as far as the motor.

There should be a number stamped on the steering neck and on top of the motor. What do you see?

What is the VIN# stamped on the steering head?
