    I have never opened one up that I can remember but I have seen quite a few with the power head off the mid section. No lower crank roller bearing that I ever noticed….I had gotten the idea of plain bearings from someplace…..I wonder where….word of mouth, I think. Upon looking at the parts list, I was amazed to see that they had roller bearings for the connecting rod right back to the K1! Wow! Anyway, I personally would still use 16:1 ratio.

    Long live American manufacturing!
