I did PYO Monkey 10's. Bought a +2 clutch, ran it through fairing, but ran it through a new hole I made behind visor bags a tad below the windshield. Totally hides the clutch cable! I did a thread showing what I did if you are interested. Did it for looks not b/c it shortens cable path. I agree with Nut I think my clutch pulls easier now. I've seen some say +4. Can't hurt. Especially if you think you might go taller someday. I did not lengthen anything else and all works great.

You didn't say what year. I have heard some say pre-09 didn't give you as much extra.

 

Without knowing what bike it is, you can't say what wires/cables are needed. The RK and fairing bikes are different...
