OK...On my Cranbrook when I still had it, I had to make my own motor mount to back it away from the front bar and settle the motor more towards the rear and at the same time, installing the motor up higher, that will solve your clearance problem...I made mine back then out of a piece of roll bar from a wrecked out dune buggy from the junk yard, but you can buy one of these to solve your problem as well.
The rear mount is fine, it's the front mount you will need.
I don't have the Cranny anymore, but it was the same scenario with my present bike, the Hyper Beach cruiser...Here are a few pics of it with the old role bar front motor mount I made to accomplish the same thing I had to do with the Cranny in order to get proper clearance.
This should give you an idea just how high it needs to be mounted as I did on my bike before I put the mags on it., etc. etc.
