hmmm... well, i know the zx9 motor will fit into the zx7 frame with minor mod of the 7 frame... so i would think that if it is possible to squeeze the zx11 mill into the zx7 frame that the zx11 mill is not far off from the zx9 mill, thus being possible to mount in a zx9 frame. i'm thinking a zx9 chasis of the same era as the zx11 would work. hell, we've seen the zx9r with a zx10 mill.
besides, anything is possible with the right tools and $$. hehe
