Unbend the wire holder on the inside of the front right of the frame to get slack in the wires attached to the radiator.

Carefully move the radiator to the right side of the bike, out of the way of the cylinder head.

The radiator is not completely disconnected from the bike, there are still wires connected to the thermo-switch and fan. Be sure that you do not put too much tension on these wires or you risk ripping them out of their sockets.
