Hardware stores and the like usually have some special solvents that can get rid of this, I think it's called "Goo Gone" or "Residue Remover" or some other catchy name.
I'm not sure if those chemicals might interfere with the carbon though (as carbon-fibre structures are essentially many layers of CF bonded together with glue.) I guess that they are clear-coated and painted anyway so it might not be such an issue.
Another option you might want to try is to rub the adhesive residue rapidly with your finger until it starts to get hot. The added friction and temperature often helps to get it off.
As an aside -- I prefer to use cut-up lengths of old bicycle tubing to put under sensors (instead of adhesive strips), for these sorts of reasons.
