"if it were mine," i'd convert in stages and do only a little in each stage. perhaps do the painted parts first, then you'd have the airbox and side covers taken care of along with the oil tank. later do the gauges after you've accumulated all the parts. if it were mine, i'd just clip the leading and rear edges of the ft.fender and call it good. or, if that fender is too nice, snag one off ebay. i'd use a "ko" cover and foam on the existing pan. (if i recall correctly, i don't believe the k2 frame has accommodations for "ko" seat latch..) for a bike i am going to actually ride and enjoy riding, i've found my "tastes" have changed. i used to think it had to be perfect = everything like original. no longer do i feel this way. the k2 will never be a "ko," even if i went totally anal on the conversion, down to changing the vins.... you get the point. it's just an old Honda 750, after all. you bought the bike to enjoy, so do a bit here and ride it there and then do a bit more and ride it some more. the paint/airbox/sidecover thing would be the biggest step. then the gauges could come later, cause you'll have to get rid of those idiot lights on the handlebars. followed by the seat and from my standpoint, i'd be done. or do the seat first, then the gauges. most people will see the bike and think it's a "ko". a few will know it's not and that's no big deal. i've ridden a couple bikes "going through transition; it's fun. those rubbers you show from the Yamiya website are the ones you need.
