It's been quiet on the exchange lately!

Well, its time to show these to the world...

These are two more original Henderson cranks that have had counter-weights added and then the assembly (including flywheel) precision two plane balanced. These cranks were also reworked and brought back to standard and new thrust surface etc. of course. The KJ is the very first (on left).

My Deluxe has one of these (on right). The motor runs much smoother and the wear on the center main is eliminated while using my light-weight aluminum bearing-less rods and 850 aluminum mains. The inertia load on the flywheel flange and end of crank is substantially reduced as the flywheels are reduced by 5 lbs. I have now beaten my test bottom end to death for over 8000 miles mostly at high speed highway and everything remains as new.

Try it you'll like it!
