Not sure which of the bearings failed. After some general symptoms showed (unexpected and subtle lack of power) troubleshooting started. As part of this rotors and belts were inspected and found to be okay and properly timed.

Symptoms continued.

We surmised that failure was progressive. So who knows when plugs were firing in or out of order.

Finally the thing completely let go and the belt broke. The cap and rotor were all broken up. This step occurred during a simple test start in my shop.

Once the engine was returned to firing all plugs, the crank broke. Saturday quali between turns 2 and 3 when I was warming up my tires. Engine went off song... clankity clank. Back in the paddock we noticed that the crank pulley was moving in and out by 1/8+ plus. Shut her down. Started packing up.
