Thread: K0, K1, K2 K3 KH0.....what da?

What do all these "HK" insignias mean, and how can I tell which one I've got? I can't see any designation of that marking on my bike.

KO is 69-71 auto, HKO is 70-71 4speed, K1 is 72 auto, HK1 is 72 4speed etc...The 72 is the last year for 4speeds. The H marking is only in the VIN of 4speeds and their engines... CT70H-xxxxxx. If it is an auto it will read CT70-xxxxxx. There is nothing on the bike that will be marked K.

This link should help.
