This one may work, anyone know what it is off, or approx size?

I cant buy one right now, but may be getting my hands on a unit off a Mini, first measurements say it should fit in the space, except for my magneto, may have to be moved.
Anyone know drive ratio on a Mini, looks like it is at leat 50& overdriven, maybe closer to 2.0...which then, looks like 1:1 on a 750-1000cc is about right..
