S.S.Bearing- What to Do about it??

[Bob Kane]

I believe OS designed this bearing problem into the 140 on purpose, just to give us something to do.

Assuming that OS doesn't offer a solution to lubrication of the rear bearing on the 1.40, what other options are available?
    What mods could be made to the crankcase to permit more oil flow back there?
    Would increasing oil content of fuel make any difference?
 
If the real core problem is undersizing of the bearing for the load application the motor endures, then a real fix would be a redesign of the crankcase to use a larger and wider bearing.  Pretty unlikely that would happen, I would guess.
    So what's the solution besides keeping the bearing suppliers well-funded??
