If you start working with those pressed together
flywheel/crankshafts, make sure you talk to some
of the Harley guys that are now on this net.
That type of setup works good for "normal" duty,
but if you're going to press it into the nine
bazillion RPM and mega HP zone, there are some
secrets they have to make sure the two ends of
the crank always revolve at the same speed. Many
years ago I built a stroker Harley without
benefit of that "trick" and I experienced having
the two ends of the crankshaft revolve at
different speeds - - - no pretty!
