Yamaha had always been famous for interchanging parts on their sleds.
i.e. The old 396 cylinders would fit on the old 338's

Yamaha's GP246 engine is based on the DT250 Enduro engine.
Does anyone know if they share the same bore and stroke?

Could you modify a GP246 motor with the GYT kit parts
that converted the 250 enduro into the 250 MX ?

Wondering if we could use the MX250 head to convert the
GP246 into a free air motor.

Gotta be an old Yamaha fanatic to be able to help me out here.

Thanks!
