How to rebuild a Keihin CDK2 PWC carburetor Kawasaki 650 750 900 X2 SX SXI TS SC jetski 

Thanks for the nice comment!

Thanks for watching What ski? I might have the settings

@@EricksonMachinePerformance I have a 1996 seadoo gti 787 dual carb

@@EricksonMachinePerformanceknow the setting for a 95 900 zxi?

Thank you! I look forward to helping u out!!

Thanks for watching

@@EricksonMachinePerformance Watching the 650 rebuild video. Great content!!!

I just saw that as well

There is a link to the cleaner in the video description

Thanks for watching and commenting. I'm happy it helped

Wondering the same thing

@@tylerbaker555 FYI mine is running great with the gasket in place above the diaphragm. The rebuild kit I bought however had a needle that was about 1/32” off from the length of the original and it would not run properly with that needle in place at all.

I will do a sleeving video in the future but kawi 650/750/800 are quite difficult to do

if your having issues starting try opening your low screws a little to see if that helps assuming you already rebuilt the carbs

email me ericksonmap@gmail.com and ill send you a diagram

If its a cdk2 carb yes

@@EricksonMachinePerformanceHow do I know if it is a cdk2? Thanks

@@chadhaas8871 email me a picture of the carbs ericksonmap@gmail.com

I'd recommend running 1

I will be honest I'm not an expert on Keihin carbs. I can get the part for you . That being said I don't know how n it would affect Performance. The and as for the diagram theres a couple different versions of the CDK-II carbs so they include for each ( i think)

I need this part as well for my dual Keihin carb Polaris jetski. Can’t find it anywhere. You say you can get the plastic piece?

Email me ericksonmap@gmail.com I'll be happy to help you out

Yes. What brand kits did u get?

We have always left that gasket out. Either way, it won't affect performance. I believe I have answered this in other comments over the years

Pudiste hacerlos funcionar?

I left it out intentionally there is no reason to use it. The rubber seals it . That gasket isn't used in all cdk2 carbs. It donest affect performance either way. It's the way I have done it for +22 years and yet to have an isse

Many times we make changes on Mikuni and Keihin carbs to increase performance. There are always reasons for making changes ect... great eye tho and thanks for the comment 👍

The pulse line creates a suck and blow for the diaphragm and there are 2 check valves that push the fuel thru the pump

It's a suck/ blow pump. If the check valves and diaphragms are ok it works. Other issue could be the reeds that stop the pump from working correctly. And making sure the hoses are setup correctly

Check your reeds. Also what rebuild kits did you use?

@@EricksonMachinePerformance one off eBay🤨 my ski is a 750 ss xi twin keihin, I’m unsure what the pop off pressure should be and what springs I should be running. It pops off at 25 PSI with the ones I’ve put in. It runs with easy start then holds a good idle with choke on. As soon as I take the choke off the idle starts to accelerate from a lean condition from the needle valve closing and leaning out the mix?

@Tom Johnson email me your # and I'll try to help. Unfortunately most of the knockoff kits are junk

Sorry it's hard to film a moving part when filming alone. Thanks for watching

Some like a problem with the pickup or fuel line. If you run a separate line to the carb and it runs it means the fuel pump and the carb are running properly

You can just use a yamaha 701 filter instead

Depends on how dirty they are. Between 30-60 min. And sometimes they go in for a second round

Can u email me a picture ericksonmap@gmail.com

Using what on an atv?

T20

No

popoff is a great way to check that all is well BUT if rebuilding a stock carb , that is in a bone stock ski and using oem parts you will most likly be fine. Performance setups are much more necessary. Many people make alot more out of popoff then it really is on a stock ski. STOCK skis can vary greatly and still run great. Many people see carbs as being magic and a popoff gage is the only tool that tells you anything BUT engines can be setup differently with different popoff pressures and still run great.

It's linked in the video. It is water-based

@@EricksonMachinePerformance thanks for quick reply man 🙏🏼

100% if you removed the oil line. there should be a 8 or 10 mm bolt at the top of the oil pump open it a could turns and let it bleed then after theres no more air tighten and check for oil flow

It was left out on purpose. Some aftermarket kits don't come with that gasket and when we used to modify these carbs we found it wasn't needed. Either way with or without it will run the same . But great eye noticing 🤘

i dont have a link BUT if you email me i can order it for you ericksonmap@gmail.com

Erickson Machine & Performance thank you I have a barn find that has a very dirty carburetor. I’ve never worked on one before so I found one for a $100. I think it might be worth it since I have a screw stuck in the old one

@@doughaskins6153 email me I might have one on the shelf also send me pictures of what urs looks like

First would be open and clean it

Email me what sizes you need Ericksonmap@gmail.com I can get them For u

1.5x turns out on both high and low

Different engines have different needle settings and jets. There is no magic number just a starting point. And that vary depending on altitude. Starting at 1.5-2 turns out is a good starting point but it's JUST a starting point

@@EricksonMachinePerformance No, start by reading what the manual says!

@@mochanic5498 aftermarket engines don't have manuals. A manual isn't always available for aftermarket setups. Also depending on altitude the stock setting also wouldn't be correct.

The problem is there are several different engines that these carbs come on and all of them are setup differently with different jets and the screws set differently

I'd start at 1 turn out on the low and 3/4 out on the high and test ( do a plug chop to make sure it's not lean )

@@EricksonMachinePerformance appreciate the response!!!

what do you mean?

Pulse line? To the crankcase.

email me ericksonmap@gmail.com

You are correct.

I was taught years ago by a carb guy that it wasnt needed so I havent used it in years. But that would technically be the correct want to have shown it. Good eye

I do have a question as I just rebuilt mine. What should the depth of the seat be?

@@r1ckgrimes97 can you email me your phone # and I'll be happy to help ericksonmap@gmail.com

@@EricksonMachinePerformance I am rebuilding a dual CDK 2 carb setup on a 2000 Polaris SLH 700. I am ready to replace the seats (bought new ones) but I am unsure of alignment as there is a hole thru the side of the seat. I didn’t realize there was a specific way to put the seat back in until it was removed. The plate the seat is placed in has an area that would allow those holes to uncovered to allow fuel into carb. Is that the correct alignment? I can email a picture of the seat if needed. Thank you for the video bc there are very few CDK 2 videos.

same question here also.

@@EricksonMachinePerformance thank you. so it looks like it doesn't harm the paint. correct?

@@grantpourciau3894 correct this one doesnt harm the paint
