Where Can I find some parts ?

I need want a new main wire harness, and right and left handlebar controls , I still can not get a spark to the plug on my 79 kz650b2 , I installed new fuses , new dyna coils , new stator , new plugs , new plug wires so I have decided to just try to rewire the entire bike as the guy before me really did a number on the electrical . So does anyone know a good place to pick up those parts ? I am at my wits end !!!! I know if I could get sparks this bike would fire right up . Thanks in advance

sometimes u can find complete harnesses on Ebay.I would call Z1Enterprises or BikeBandit and see if they can assist u.bj

Fleabay or the many online bike dismantlers would be the place to look.
