i was going to say build a cafe racer then scrolled down to your pic. i'm getting ready to start a scrambler build with my '73 yamaha tx650. good luck with it. we will have to go ride when we get our bikes done. let me know if you want suggestions for sourcing parts. i've been researching cafe/street tracker/scrambler bikes for a while now. found a lot of good sites. all from google so i'm sure you will run across them as well. i just sifted through some of the BS already.
does the kawi have a driveshaft or belt?
