Well, while throwing in a new stator I noticed my crankshaft has no radial play, which is always a good thing, but can be pushed in and out maybe 1mm of total play.. seems like a lot. I have no real experience to use as a baseline here.

My 99 has always had a mm or 2 of play in the crank....your not the first to bring up the same question..........if I'm not mistaken its the type of bearings used....the older bikes are more noticeable....
If I'm not mistaken the crank bearing is a taper bearing vise a roller bearing......but then again I may be all wrong.....never split the cases on my 99.....what ever the bearing is...there good stuff!
Right the 99/2000 250/300 had 2 6306 ball type bearings. in 2001 they changed to a 6328-c3 on the right side and a roller type bearing on the left and no shimming so the right side took all the side loading which caused an early failure or the right main bearing. This can be converted to a ball type bearing which allows the two bearings to share the side loading and makes it more reliable. Not to mention alot more affordable than the roller bearing.
The 99/2000 models also had issues of the OD of the crank improperly machined to smaller diameter causing the crank to spin inside the bearing (no interference fit) the bearing would often slide right onto the crank spindle by hand.
