Ernest,
The Suzuki AC Generator is 400 W @ 5,000rpm, the ( no-load) voltage is 70 V (AC) @ 5,000 rpm regulated to 14-15.5 V @ 5,000 rpm.
I thought Amps was Watts/Volts ( 400/ 70 = 5.71) but that doesn't appear to be case here, what should I be dividing the 400 by?
I figure it must be about 30 amps as that's the main fuse

I was thinking I could fix the rotor ( with pick up) to the back of the PSRU and attach the generator shell to the flywheel damper assembly.
That is EXACTLY what I'm doing. Attaching the stator to the back of the PSRU was stone simple. I turned down the PSRU's back cover plate so that there was a ridge that fit the inside of the stator. With the stator thus located, I match drilled four of the mounting holes into the back of the plate. I countersunk the other side of the plate then used four flat-head screw into 3/16"x3/4" coupling nuts. 3/16" pan-head screws through the stator into the coupling nut, and I was done.
The rotor is going to require that I do some precision metal bending to get a viable standoff. I might try milling the standoff from an aluminum plate. Haven't decided.
If your design is easier I am happy to look at that as well - I'm just researching as much as I can while I have some time to do so. I have some big projects coming up soon. One thing that concerned me about the permanent magnets was the heat sensitivity. What Amperage is your generator?
It's a 35Amp generator that will be stuck out in the wind fairly well. All the intake air will be sucked passed it before being blown into the engine. Heat will be less of an issue than in it's designed environment on the front of a Harley.
