I have a 1978 CB550K3 with Kehin PD46C carburettors, I need to change the main jets, but I cannot see how to change them.
When I remove the main jets they are attached (very well indeed) to the emulsion tubes, my Haynes manual carb diagram show that they are pressed together with an O ring, now this must be a bloody good fit as I cannot see a join.
Am I (well my manual) correct and that they need separating or am I missing something simple?
