Minimal differences at best. I think we have the evaporative something canister, which might add all of one pound to your bike (and can be taken off, if you only use the bike on track days (eheheh). By now, most makers build for a global market and Euro 4 emission standards are pretty stringent, so almost any bike will come awfully lean, etc. I think the differences between non-CA and CA bikes are not as significant as they used to be.
I might be wrong, though...
