Okay thanks. The cases are the same between the 750 and 850, per visual inspection of one of each in my grubby little hands at the same time. The diameters are the same for all three stators and all three will fit inside either rotor. mounting holes are the same on all three stators. The rotors of course have different magnet patterns and the 850 appears to have a larger balancer. As far as crank dimensions and fit I have no idea so maybe a crap shoot... Hopefully they have a 12 pole unit but they list the same stator for all 77-79 750s so maybe they only have 18 pole stators and just don't know any better. In which case I'll have to insist on a refund and go with someone else. This all needs to be hashed out with them, please wish me luck.
