yeah, i'm not sure what he is talking about. If his bike is a 1970, it is a K0.
I think he is confused about the carbs too. Sounds like someone said such and such and he took it as dead fact.
There were multiple iterations of the 4-1 throttle cable. I think he is just confused, his confusion carries over to the reader though, what he appears to be talking about really doesn't even warrant mentioning.
