I had some friends in college that had one with a 90cc 2 smoke retrofitted into it, really fun little toy. I think I still have a few scars from it! When you got her running at the right RPM and around 20mph you could punch into the powerband and walk the front for as long as you could hold it. The trick was holding your weight out over the front of the bike once you got it on the back tire. Once your ab muscles started hurting from the strain you better sit her down or she would put a whipping on you!
I think you should loose the body work and try to replicate a cafe look, I have never seen a pocket cafe!
Cheers
