premature bevel gear wear - what's causing it?

Alright fellers. Here's the running video.



Here's a couple pics of the gears. This is after about ten miles of riding. Notice that the wear pattern on the small gear is not aligned with the teeth of the clutch basket gear.

If my memory serves me right, there was a batch of engines & clutch bevel gears, that were machined wrong, out of specs. The particular clutch bevel gears were machined under sized on the overall diameter, resulting in excessive gear lash/ loose gear lash.

The excessive gear lash resulted in excellerated bevel gear wear.
