If that bike says "cafe" to you, maybe you misunderstood and it was telling you it was hungry.
Seriously, that bike is not a great starting point for that kind of build. It is not impossible, but you are handicapped from the start. The frame geometry is wrong, the shaft drive is a minus in the performance department, it is heavy....even for a GS. It is a good bike, don't get me wrong....it is just more suited for touring, than performance. It was a smaller alternative to the GL1000 Goldwing.
