After the stress of removing the Yamaha DT125R crankshaft and pulling off the left hand bearing, it is best to inspect the measurable parts. I looked at runout which tells if the crank rotates on a level plane, the limit is 0.02mmm. Next I measured the width which should be 57.90 - 57.95 mm according to Haynes. I then measured the big-end bearing axial clearance which was 0.51mm, the tolerance is 0.2 - 0.7 mm.
so all in all I was satisfied that the crankshaft is fit.
I did not measure the Big end bearing radial clearance in this video, because it was running and seems fine.
Thank you for watching and reading the description.
