I've built lots of cranks for these bikes and they would routinely
last at least a thousand RACING miles. They do have to have to be
properly trued and have sufficient clearances everywhere, but there's
no reason why you shouldn't get lots of street miles out of one of
these things.
Bill not to nitpick but Bob had a rod break in half NOT a crank.
If you'll take another look at what he posted, the big end rod
bearing failed and the rod nearly broke. These cranks are pressed
together assemblies, the big end of the rod is one peice, no rod
bolts, thus it's part of the crankshaft assembly which is what I
should have said instead of crank. Back in the days when I did a lot
of these things we just called them cranks. Take a look at this
schematic;

Couldn't a frozen piston have caused all this rod bending and bearing
torn up as well? Say it happened slowly and not in a few milliseconds.
The sides of the piston are gauled too. I should send some photo's as
it's right here with me.
