  • What Keihin Carb is in the 2000 PRO1200?

    Might be checking out carb rebuild kits soon, exactly what model Keihin carbs do I have in my machine? I believe they are 40 mm's, are they what is termed as CDK II's?

    Dumb question I guess. But I haven't purchased the Polaris manual on this one yet.

    Thanks

    CDK-CV's - dealer only kits, about $100 ea.

      The Polaris online fische (Partsland)shows them at $59, but that's likely the offbrand Polaris sells, are you talking of the Keihin OEM kits? Steep regardless, ouch!

      Anyway, I do appreciate knowing what model I have, I didn't know and couldn't find it anywhere. Russells-pwc.com apparently doesn't have their specifications link for all brands up anymore.

      I may not need the carb kits anyway, as it turns out. What I was seeing as a fuel leak coming from somewhere on the outside of the carbs (was blowing my mind figuring that one out) now appears to be centered in the accelerator pump area. Are these supposed to be simply replaced when they blow or is there a kit for them too? Polaris lists an "accelerator kit" for around $34.

        actualy, i think the polaris carbs are CDKIIs, the CV are kawi carbs (ultra)

          yah, looks that way. Partsland.com diagram shows the rebuild kit as the same one as my sl900, part #2200910

          Looks like you should be okay with a standard cdkII kit?

            So tell me, is there a "breather hole" down at the bottom of the carb covers on the diaphram side of the body? I now think that's where the gas is dripping from, not the accelerator pump. And this would tell me I have some holes in the diaphrams, correct? What gets me is its on two of the carbs, like as if clockwork they both went.

            Sorry to bounce back and forth on this, just gotta get it fixed and up and running again. The carbs have never been opened, so it's certainly time to do the kits.

            Heading to the carb rebuild section on this site to do a little reading. :)

              Looking in the SBT guides, my carbs are the CDKII's.

              Now correct me if I'm wrong, but it's my understanding that if I re-use the same spring thats in the carb when I take it apart (which should be fine), I don't have to worry about the popoff, right?

                Assuming your popoff with the current spring is correct (of course, assuming), then yes you should be fine.

                  Does the "hole in the diaphragm if gas is coming out of the cover" theory seem right?

                    You're right, my mistake - those are CDK2's. I would agree if fuel is flowing out there the diaphragm has a hole.

                        Update - got the kits, pulled carb rack, started into one of the suspect carbs on the diaphragm side, and found that the internal screw that holds the regulator section to the main carb body had worked its way out, dropped down and was lodged at the bottom area of the diaphragm. Huh! put the screw back in temporarily, went to look at the second carb, same thing. Third carb was ok.

                        Still going to do the kits, as well as the dual fuel pumps while I have it off, regardless. Also, pulled off the manifold and checked the reeds - they looked perfect. Also peeked in as best I could to the crank and the piston/cylinder bottom areas - looked great, no streaks or scratches whatsoever.:)

                        Again, thanks for the help. Thought this additional info might be of use to other folks who have Keihin-equipped machines.

                            They had never been touched prior to this opening.

                            I presume a little blue locktite on these screws wouldn't hurt anything?

                              I'm not a big fan of using blue loctite on small screws inside carbs. Since the screws are so small to begin with, they tend to strip out quite easily. I do believe you said on the carb body? In that case, it probably wouldn't hurt.
