I would just remove it and run the 'open' cable only (Oh, I already do that ;D )
No need to remove air boxes or carbs remove 3 screws on handlebar switch, 10mm open end to remove locknut at carb end, needle nose pliers to remove carb end, don't break throttle barrel at handlebar end.
Re-fit opening cable nipple into closing cable hole at carb end of cable.
BTW, remove fuel lines from carbs if you need to remove carbs from engine, make things easier, no need to ever remove battery box, remove carbs to right side of engine with cables still attached, loosen locknuts first though as it's easier when carbs are held by manifolds
