my father in law was talking this weekend, that he used to have a R5 Yamaha.

Pretty cool info.

do the twin carbs clear the stamped frame of a CD?

yes
only trouble you have is with a 200 engine in a 175 frame is the engine studs. shave 3mm off each and use standard nuts with copper washers instead of the domed nuts
