I have dual carbs on a 750 zxi I’m planning on rebuilding. I Already bought both carb rebuild kits and fuel pump rebuild kit. I’ve never done a carb before I was thinking about having someone else do them. Your step by step makes it look like it isn’t THAT hard.

I rebuilt the same carb this winter and after I blew the engine last week I took it apart again. I found the same loose screw you just did at 3:09. not uncommon I guess. tightened it as hard as I could this time. We'll see next spring

[@jeffmcdermed8595]

Thanks for the informative videos! Question for you. I have a 97 kawasaki ZXI 1100. I'm changing the motor to a 98 kawasaki 1100. Can I still use the 97 carburetor on the 98 engine? The 97 carb has two hoses that connect to the engine, but the 98 only has one port for the hose. Is there a workaround for this situation? Can I put a tee on the single port to accommodate both hoses? Thank you for your expertise. Jeff

Dude, you are awesome for making this video. Thanks so much! I just bought all this stuff to do this job later this week. I've never pulled a carb apart despite owning 10 two stroke skis, but it's time I learn... What do you use for your ultrasonic cleaner solution?

I have both the CDK2 Keihin carb and fuel pump rebuild kits. Neither have the replacement o rings for the high/low adjusters. Did your kits come with them?

[@EricksonMachinePerformance]

Yes. What brand kits did u get?

[@RVCrazy]

Any reason why you left out the gasket that goes on top of the diaphragm with metal on it? I kept expecting you to circle back to it saying you forgot it.

[@tylerbaker555]

Wondering the same thing

[@RVCrazy]

@@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.

[@justinnehring7339]

What does the little plastic piece do that gets reused in the main body of the carb (the piece that sits about an inch below the plastic venturi check valve)? My carb doesn't seem to have one, although there is an empty spot for it. Any idea what problems I may have running without it? Also (lastly), why do all of the rebuild kits come with two of those plastic venturi check valves?

[@EricksonMachinePerformance]

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)

Hello I have a Kawasaki 650sx I can’t get the fuel system to prime it will run by dumping gas down the carb but not any other way please help

[@robertpeck8683]

You just eye ball the needle spring? No pop-off pressure check?

[@EricksonMachinePerformance]

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.

hey @eriksonmachine&performance i have 2 1997 polaris slt 700 and i want to replace the in-line fuel filters but I cant find any specs on them or direct replacements. any recommendations?

After rebuild do I need to bleed the oil injection system? If so how do I go about it? Thanks

[@EricksonMachinePerformance]

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

[@madsembastosmarques2411]

I have difficulty when first starting the jet ski Kaeasaki 750 SX you need to inject gasoline to work the pop off is at 25 psi and low 4 and high 2

[@EricksonMachinePerformance]

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

[@andrewwilson2418]

How many turns for the jets

[@DiyExtracts]

😢 I broke the plastic t fitting on the middle of the ther carbs , I believe it’s like a primer valve but can’t find any replacement online can I block it off ?

[@EricksonMachinePerformance]

Can u email me a picture [e-mail]

[@brendonnelson814]

I followed the video step by step but for some reason the fuel pump will not provide fuel to the engine. If I run it on an external fuel source straight to the carb, it idles and revs perfect

[@EricksonMachinePerformance]

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

[@joeeberhardt5409]

Is there any way to test the carb pump to make sure it is getting fuel to the carb?

[@EricksonMachinePerformance]

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

[@DiyExtracts]

I have an ultrasonic cleaner what type of solution do you use to clean carbs ? Nothing water based right ?

Hi, I replaced everything including springs and don’t think it’s pulling any fuel through the carb. I’ve tried putting compressed air through the inlet side and blocking off the return I get over 35 psi before I get pop off. Do you know what pressure pop off should be I’ve got the exact same carbs on a 750 xi ss kawasaki

[@EricksonMachinePerformance]

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

[@tomj337]

@@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?

What are the stock settings for the low and high speed adjusters

[@MrAwesomealex28]

1.5x turns out on both high and low

[@EricksonMachinePerformance]

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

[@mochanic5498]

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

I was about to ask if u forgot the gasket @ around 15:30 but looks like someone else in the comment section was thinking the same thing

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

How did you manage to put the Cover plate over the jet side and forget to put the large round gasket on. The one that was left on the table at the end? lol. Great video though!

[@EricksonMachinePerformance]

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

How does that fuel pump work with only 1 fitting for the pulse part of the pump 21:45

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