The 2014 Cannonball Run is over and the Bosch ZEV magneto performed flawlessly for the 3000+ miles without having had any maintenance since I originally restored it for use in the 2012 Cannonball.

Bill Wood happened to mention at least four failed magnetos in his daily posts about this year's Cannonball. Although there certainly could have been others as well, given the 1936 cutoff for this year's event meant most bikes did not have magnetos, so even four is a very high percentage of failures. However, between the bench tester and actual road miles my friend's magneto has traveled over 5000 miles so far, which is consistent with my contention that there is no excuse for a properly rebuilt magneto to fail. And yet, "professionally rebuilt" ones continue to fail with remarkable regularity...

I've asked that this thread be unlocked so it is open again for questions related to magneto restoration.
