I was beginning to wonder if the mail made it out, since no one up till now
had a comment.
One thing I failed to mention is that the dyno guy cut the bike off at the
end of the final pull & let the bike coast. The computer software compares
how fast the rear wheel slows down, to the acceleration during the pull. What
you end up with is the HP expended in turning the rear wheel. In my case the
drag from gear box, u-joint, drive shaft, rear drive & so on was 6.1 HP. The
dyno guy was quite suppressed & impressed that a drive shaft bike had this
low of a number.
The 700cc motor I started out with had 35HP, so I gained 5 HP from those
50cc.
