Try one more thing first. Unplug the VOES. Really
simple. It will be stuck in the more retarded
position. Then ride till its hot and see what happens
to the pinging.
Not sure what this will tell you, perhaps an

was absolutely no pinging whatsoever. It had poor
acceleration, but it was nice not to hear that
irritating noise.

Above all, we must realize that no arsenal, or no weapon in the arsenals of
the world, is so formidable as the will and moral courage of free men and
women. It is a weapon our adversaries in today's world do not have.
