Not necessarily the crank grinder's fault... Deve's page gives me the impression that the block manufacturing(ie crank journal holes) wasn't that great to begin with.
My crank is ground .01" undersize & has 'matching' bearings
The manual i'm looking at says new bearing clearance should be .001-.003, used .001-.004
So I'm pretty close to spec... but the foil (a little less than 1 thou thick) makes me feel better by being on the tighter end of spec.
