SKF crank bearings.
I am doing a motor now that it looks like the plastic cage on the flywheel side started to eat in to the engine case? anyone else, the stator was also trashed,like it had a lot of endplay. I have half of the diamond racing bearings in my motor, two seasons ago i ran ball bearings on both ends of the crank. then I last seaon i switched to a ball beaing on the flywheel and a two piece roller on the cam chain side, not failures ever, I like the ball bearing cause it eliminates the flywheel wanting to get in to the stator.

Whoa! thats cold for sure!
Don't forget I just gave the minimum clearances, so that would be a bearing bore on the low side of the tolerance and a crankshaft on the high end of its tolerance. So when you build an engine you may want to measure both then decide. This would be critical if the person is going to be riding in cold temps. The max clearances are as follows:
20C .0576mm
150C .1067mm
-40C .0349mm
In any case I think in most situations the c3 clearance would be fine...
