How to remove and clean Mikuni Flat Slide Carbs on a Polaris IQ or Fusion

[@snowsolo]

Awesome! Thank you! Have my flat side carbs out of my 05 xc 500 sp and on my work bench now ready to be cleaned. This was great timing.

[@StreetersGarage]

No problem. Let me know if you have any questions

[@aceyorba]

Could not get the pilots out. Tried all different combinations on the screw drivers. .i didn't want to strip them so I cleaned and sprayed air the best I could. Do you need to do anything with the top of the carbs/slides?

[@StreetersGarage]

Typically you don’t have to deal with the tops. But it would be good to pull the caps off and inspect the slides and make sure they’re not cracked. If the slides are green in color, they’re prone to cracking. If they’re black, you should be ok.

[@aceyorba]

@Streeters Garage thanks for the information .

[@StreetersGarage]

No problem. Good luck!

[@bryan7087]

last time I cleaned the carbs on my IQ, it took me longer to figure out how to get the airbox back in place than it took to actually clean the carbs lol. Biggest frustration of my life is that airbox

[@StreetersGarage]

Yes. It’s an exercise in patience.

[@moparsrt3941]

First time was a charm! Second time was a pain 😡

[@grantpiper3424]

Hello, thanks for the vidoes. Do you know if the part number for the orings the same for the 04 polaris 700 switchback? Carbs look identical.

[@StreetersGarage]

Here you go. 1921401 - Polaris Part Number KV/10 - Mikuni Part Number

[@grantpiper3424]

So will the 3130533 orings not work in my carb?

[@StreetersGarage]

Sorry. 1921401 isn’t correct 3130533 is the right one.

[@grantpiper3424]

No problem thanks for your help appreciate it. Happy New Year!!!

[@anthonysgarage]

Great video!!! Bout to go through the carbs on my '03 ProX 600, and those carbs look identical to what I have. I suspect those o-rings you were talking about are my problem.

[@StreetersGarage]

Yes. They’re identical and make sure to get the o-rings. It’s pretty much the only thing that goes wrong with them

[@anthonysgarage]

@@StreetersGarage Fo-Sho. I won’t even crack them open until I have the o-rings in hand. Thank you!

Same issue with my 02 700 RMK...

[@stuartsteele821]

You really have some great videos thank you! I have a 700 and 800 edge chassis. Any tips to dial these into making them start easier? Mine is typically a 6-8 pull to start from cold. Anything to look at first. Carbs are super clean?!!

[@StreetersGarage]

Thanks! Typically they should start on the 3rd pull assuming that you have good compression on both cylinders. I’d check that first.

[@stuartsteele821]

@@StreetersGarageCompression is good, new top end. Thank you

[@t2722]

What carb settings worked best for you on this sled in terms of jetting, screw turns and needle clip position? Right now my current set up is this 400 main jet Stock 145 starter jet 45 Pilot jet .6 Pilot air jet Stock needle position 2 Screw turns? I’ve heard a lot of people going to the .9 or 1 pilot air jets and maybe raising the needle to position 3. But going over the discussion boards everyone did something different. Thanks

[@StreetersGarage]

Honestly, I don’t remember

[@TaylorGalarneau]

My 99 xc 500 has these..my bottom end keeps flooding fast, gas isnt pouring out the over flow so it's not a stuck float, think it's them orings?

Definitely.

[@jpskiskate2000]

I’ve got an ‘03 rmk 700, what’s the difference between the spi part number vs the one you showed in the video? My carbs look the same as in the video

[@StreetersGarage]

@jpskiskate2000 same part. Just from a aftermarket support versus Mikuni.

[@marcolaufer6279]

[@mj07469]

Any idea on how to adjust the float heights. Do you adjust them for level with the carb upside down ?

[@StreetersGarage]

You want the brass float arm parallel with the with the edge of carb body.

[@mj07469]

The carb float asembly are all 100 percent plastic. No brass tang to adjust. Found my floats both just a tiny bit below level when viewed upside down. They are holding,blocking fuel when closed. Tested them with my mouth blowing air into the carb gas input plastic T line. Yuck,Yuck.. Took them apart. Now need new o rings. Might you have a spec, part number ? Wanted to check seat for debris, corrosion. Also...great tip on reconnecting float bowls and then tightening drain bolt before the holding phillips screw.

[@StreetersGarage]

Yep. Sorry, I didn’t realize what video the comment came from. Part number from Polaris 3130533

[@loganbecker3515]

How manny washers are on each air screw?

[@StreetersGarage]

Not sure. 1 or 2

Cut a slot in the screw with a dremel tool and use a regular screwdriver to get it out.

It pops off. Pretty easy.

[@partlow85]

Are these carbs similar to the flatsides I have in my 2000 RMK 800 ? When I let my snowmobile sit for a couple of days the whole engine fills up with gas.

[@StreetersGarage]

Yes. Exact thing. Make sure to get the o rings

[@fordpickupjaybird1]

Do you have the amount of screw turn specs for this carb? Looks like the same one as my 2002 polaris indy 500. I need to know how man turns on each screw that factory calls for. Someone tampered with mine and I don’t know if they’re set to spec or not.

[@wallacenaaz5132]

How do you set them? I just got a sled and want to fine tune idle, and air fuel mixture

[@StreetersGarage]

Start with the baseline specs from the service manual and go from there. For setting slide height and idle. Take a look at the video I did for the Indy 500 round slides. It’s the same theory using the correct drill sizes. But with the Flatslides it’s much easier since it’s a single cable that you’re adjusting. Set the cable for the slide height and then use the idle adjustment screw to bring it to final.

[@peglegtoo]

hi, you said you would post a link to the homemade tps tester. it would be great if you could pass that on. also, where did you get the jet screwdriver?

[@StreetersGarage]

[@robertcummings3rd34]

Curious about the cheaper homemade version, did you make yours? Did it work correctly and give you correct reading to set tps? Could you send link for directions anyways pls?!?

[@robertcummings3rd34]

I cannot easily adjust or tweak my tps sensor with T.B. installed on sled. I had to replace my tps and didn't record original position and first attempt was shots in the dark. I tried three other times with removing T.B. and adjusting tps on work bench with my snap on modus scantool. I now have it close but not perfect.

You have a stuck float. The bowls are overflowing and running out of the vents.

@@StreetersGarage thanks. what would cause the float to stick? I posted this on a Polaris page and many are saying the needle must have dirt or rubber is dried up and not seating properly causing the fuel to pump out ?? I have to re do the whole job.

Did you replace the o rings?

I did not disassemble the plastic floats and take the needles out and clean them , I think this was a mistake. I didn’t know enough about the carbs until I now am researching all of this. I’m going to this time. Hopefully it’s just got some grime in there and I don’t need to buy new needles. ? I really thought those O rings were surly the problem. So I just sprayed lots of carb cleaner through the port of the needles and blew them out good
