How to rebuild a Keihin Carburetor | CDK2 

Great to see you expanding beyond BRP. Nice work. Looks well-done as always.

Great vid here!

Where did you get your pressure tester. Is it the same pump that you used for both the diagram and pop off test? I rebuilt my CDK2 just for maintenance and I cannot get it running correctly. I’ve gotten it close with changing the needle valve springs but can’t get tot to run good enough to put it back in the water. It’s a 1992 550sx with pretty low usage. I did do a compression test (I live at 4,000ft above sea level) and it came in at 130psi exactly on both cylinders. Thank you in advance and your video is the best one I’ve found so far.

The fuel pump pressure measured at 5psi for 10 seconds. If it won't hold any pressure is it a sign that the plastic gaskets are bad or just a gritty pump that needs a rebuild. Thank you.

Looking for that plastic low speed metering Collar. Do you have any around.

QUESTION - I’ve got the same carbs, I’m thinking of buying a rebuild kit, it comes with everything except the needle and seat. Should I worry about that, or do I really need the needle and seat, and also the jet? I feel like the most important part is new gaskets. Also, if the ski will mainly only open up rpms on water if I play with choke, shouldn’t the carb rebuild fix that? Thanks!

You do mail in rebuild services?

What did you use on the fuel pump screws.

Where do you source your carb kits from for this Keihin. So many aftermarket ones online. These are OEM?
