Oh that’s another thing that tripped me out. Why the hell would they do that I don’t know. I watched some videos on that and they say double and triple check by taking measurements. Mine was CBBC but I miked the crank journals and the crank journals all measured 2.500 and I measured the new bearings I got that came in a re ring kit, installed them with no crank installed l, tighten the main saddle, did my measurements on all of them and all came out 2.502 so .002 for oil clearance should be good.
