I recently posted a pic of a modified '71 cb500. I was advised that lowering blocks and maybe a change in the shocks gave that rear end a "relaxed" look. Performance issues aside, could a longer swingarm (by an inch, even) provide the same "relaxed" or stretched look? If so, to avoid excessive changes, what, if any, stock cb swingarms would provide that one or two inch difference on a cb350f. If it were as easy as trading up to a cb500 swingarm, that might have the same/very similar measurements, mounts, etc. but be just a little bit longer...well, that sure would be great!
