I was watching a Jay Leno's garage, and he had car on which was an old Honda s600 with a CBR 1000 RR motor in it.

I know the little legends, and midget race cars run bike engines as well, I would think a gutted 914 with 12k RPM mid engine set up would be a blast!
Anyone see one out there, or see it run?
