  • 02 Virage 700 - cdk 2 44mm - can't find accelerator pump diaphragm

    I am having a very hard time locating a diaphragm for the accelerator pump on my keihin 42mm cdk II carb. Anybody know something that I don't? An tricks you have used? I'm stuck here as to what to do. It is leaking gas. Thanks!

    Thank you very much!

    Yes sir, it is leaking where the cover meets the housing bypassing the outer "seal" on the diaphragm. This started happening only after I disassbled carb, ran it through the sonic cleaner, cleaned all flanges lightly with scotch bright and reassembled.

      What color is your carb ?
      Stock-black = 40mm
      Red or Blue = 38 or 42mm.

      The stock Polaris 40mm carb is different from the aftermarket or Kawasaki accel pumps that I have seen. The length of the rod attached to diaphram is ? longer ?
      Polaris sold it as a "kit" that is not available, 2200732

      If the diaphram is just leaking, maybe areal tiny amount of fuel resistant sealer. (RTV? maybe the ultra black)

        I did put a very small amount of sealer around the outside this morning. We'll see if it works.

            Correct. I made a mistake. Not sure how or why I typed 44.
