You'd have to fudge the shape of the grip a bit, to fit the motor. And you'd probably have to change how the stock attaches to the receiver, because of how you'd have to slide the whole stock/grip over the motor.
The front handguard looks longer than usual, so you'd have to extend the rod on the front trunnion that the exposed portion of the gas tube attaches to.
Civvy/Sportster stocks annoy me, on a personal level heh
