Rodger,
Take a look at ALL of the aftermarket belt drives out there being used on Harley and Harley clone motors such as the S&S, RevTech and Ultima, just to name a few. Many of the Wedge motors used by low production motorcycle companies were make with belt drives right from the get go. The stator does get "some" primary oil, but it is far from an oil bath. Oil is only up to the bottom of the clutch pack in the rearward lower section of the primary cover. The rotor full covers the stator and by only shear desperation does any oil ever find its way into the dark recess of the stator.
The new Centa rotor has to be bored out in the center to fit the splined hub of the Centa drive end. Then drilled for the six or so flathead bolts to attach it with. I don't think that will be a hard thing to do. The original Harley M3W compensator's rotor just used the spline it had and slid over the crankshaft end and got smashed between the housing and the end of the crankshaft. These did have a tendency to to wear out in the splines a bit and rattle.
I'm sure there are regulations that if enforced, could give some hope of parts for the future needs of the M3W's.
There are aftermarket companies that make pistons for the S&S motors, so that should not be an issue and the cylinders can be bored a couple times too. I'm sure that companies like James Gaskets could supply the necessary gaskets and seals, if someone asked them to do so. There is really quite a market for such parts at this point. There could be as many as 4 to 5k of these similar motors used and still in use around the world.
Good luck guys!
Dan
