My project bike, #4286 came to me with an early K1 motor in the frame, and it's a good motor.  I could clean it up on the outside and be done with it.  But, I was lucky enough to find an early sandcast motor, #371, which came to me with an unknown internal condition, and a diecast head and cylinders.

My question lies in the value of the finished, restored product.  How much less could I expect to fetch for a fully restored mid-number sandcast with a K1 motor vs. a much earlier sandcast motor?  I haven't been able to find the correct head and cylinders to rebuild the early motor, and I'd like to finish the project by the spring.  I would have thought the K1 motor was a replacement from the '70s, but 4286 was listed on this site with motor 4491.


Any input is appreciated!
