KZ650B1 cam chain pin count

Does anyone know the length or pin count on the peanut 219T cam chain on a KZ650B1? I know the Z and KZ100 thru 1978 used 122, is the KZ650 shorter?

Well did a little research and it appears they didn't use a typical 219T chain like the Z and KZ1000 but a Heavy Duty version with full plates, not peanut shaped. Shows it being a BF05T X118. So i guess the question would be if anyone had replaced their cam chain with a pressed Master Link style? What brand and availability Please.
