Brake/Throttle cable size.

85″ extended brake cable.     75″ for throttle cable.

Keep in mind if you have a flat side carb (OKO) you will need a flat side throttle cable. If you have a NCY BEARING Throttle and a CVK carb you will need the kind that screws into the bottom of the throttle handle and not the kind that is held on by a bracket like the stock one.
