Brent, my A snapped a crank. I saw above where you said "failure to grind the proper radii on each end of the journal pin". He said the radius was the thing that caused the crank to snap. I sent a crank over to that big time shop in central southeast PA that had never been cut. They cut off 10, counterweighted it, balanced it, Then added 30 lbs lightened flywheel, and balanced again, them pressure plate was added, and all balanced as a unit. That's 4 balance steps. Everything was matchmarked with a spray can, disassembled and sent back to me.

In any event it snapped. Please expalin in lay terms what this is.

Thanks,
Gene
