I was hoping to get lucky with matching numbers before I looked.
I would say both motors are original to the frames. The HKO for sure is.
There's no doubt, in my mind, that is the original engine. The chance of another H engine coming along within 400 #'s apart, ending up in your bike, is pretty remote. They're usually a few hundred apart anyway. I am curious though to know what the head casting #'s are. My original K1 3speed's head #'s are E10 3. No one seems to know exactly what they mean.Seems like HornetGod and Racerx are up on the vins pretty good what do you all think about the vin being off on the HK1 being 429 appart from engine and frame ?
i'm sure there's no order to it, other than the explanation of someone who was in the factory at the time.
