Anyone spot differences from previous versions?

still PM that's a fact.

I can measure on request

I -think- it is 19 splines (counted but didn't write down..)

outer diameter about 21,5mm, inner about 19,2mm

I wouldn't put a flywheel on this spline... I think I'd re-use (part of) the original gearbox with the bearing + axle if I'd have to mate something to the motor.
