    Default How do you check pop off pressure on 38mm mikuni BN series

    The title says it all! Im looking to see how you test the pop off pressure on a 38mm Mikuni BN (Round body).

    And on a Keihin CDK 2 what is the fuel inlet line and which one is return?

    Im pretty sure return has a big R on it or bye it.

    Nope not that one! That is for sbn series I have the round body pump 38mm Mikuni.. If I remember right, that back in the day (1989) they would check the pop off on a Mikuni 38mm BN series bye putting the check tube on the return line and then put their finger to block the air hole. The air hole was on the flat face of the round section of the carb, the diaphram would lay against that surface. About 7'o clock from the needle and seat.


    Is this right?
