Hello. I would like to correctly identify my cb550 for when ordering parts and checking specs. The compliance plate states that it is a cb550K built on 2/1978.
But the serial numbers identify it as a cb550K3 1977 model according to the sohc-4, model guide.
frame cb550K 20-----
engine cb550E 20-----
It is an Australian import.
Thankyou. Mike.
