Not sure if this is the right place to post, I figured electrical for "ignition key." I just bought a couple NOS '77 KZ650 keys from eBay, and they are perfect. Just be sure to check first to see if the seller has a key with your bike's 3 digit code. I am not affiliated with the seller, just a happy customer.
