can you change just wires on 1978 CB750f, or do you have to change coil and wires. called up honda they said they sell it by the foot. i thought great so i went bought wire. took coils off figured they thread in to coil. i started to unscrew but it didn't feel right. with closer inspection in kinda looks like they my be part of coil. i don't want to have to change coils and scared i my already made problem worse. can someone please help me with my question. ps. if you do have to change coil pack will coils off a 1979 CB650 work. thanx jay
