This kit saved my 125sx too. The bog from factory was brutal.

[@groundzero-979]

Oh yeah Like nails on a chalkboard I still wanna upgrade to a Lectron carb but this was a really good fix till then

[@vsavage_old_rockerz]

[@groundzero-979]

Hell yeah nice to hear the cars coming along. I definitely understand waiting till spring just got back from Maryland and it snowed the day after I got there lol. Stay safe my friend keep the car updates coming

480 main 35 pilot Blue jd needle on clip 2 1/5 What’s a good starting point for the air screw? Cheers

[@groundzero-979]

I started with 1 3/4 and ended up a hair over that

[@robhayter484]

@@groundzero-979 thanks will give that a go

[@groundzero-979]

Feel free to let me know how things work out. I noticed that your jets are kind of rich you must be at a higher elevation.

[@robhayter484]

Will do ! I’m at sea level , I put a HGS silencer on it and it didn’t like the 32.5 pilot, had a lean bog so I used a 35 ran better but still had splutter 1/2 throttle , could probably drop the main to a 470 I’ve done the jet block gasket

[@groundzero-979]

@robhayter484 oh okay that make sense let me know how things go

[@2StrokeSmoke701]

My ktm 125 sx 2022 is boggy too i just bought a lectron carburetor hopefully that fixes the bog

[@groundzero-979]

Those carburetors are really nice just out of my price range right now

[@Rooster_2007CTSV]

I found the kit on the jd website but it says it’s only for 17-21. What year is your bike? I’ve been dealing with the same bogg you’ve been dealing with sense I bought mine from the dealer. Mines a 2022 150sx

[@groundzero-979]

It’s a 2022 125sx but the same kit will fit your 150sx Here’s the link I got the kit from it shipped quick www.ebay.com/itm/144680231799?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=NVnBkoMXRCC&sssrc=4429486&ssuid=3z7b-0-oQv2&var=&widget_ver=artemis&media=COPY

@@groundzero-979 right on man thanks for the quick response I’m going to order it & im sure it’ll clear that bogg right away probably going to buy some vforce reeds while I’m messing around with it too.

[@groundzero-979]

@Rooster_2007CTSV hell yeah! let me know the out come. I was able to fix 99% of the bog on mine I’m hoping to upgrade to a lectern carb in the future

[@Rooster_2007CTSV]

On one of these other comments I seen you said go up a size with the jet depending on the pipe, I got a fmf factory fatty with a shorty. The jd kit came in today. Also ordered the vforce v4r reeds I’m just waiting on the reeds to get here to put the jet kit in. What would you suggest for the main jet..

[@groundzero-979]

@Rooster_2007CTSV yeah your going to have to go up in jet size’s and probably mess with the air/fuel a little bit the needle should be whatever the paper says shim or no shim

[@wyattstewart742]

I have a 2018 ktm 125sx and it runs great on the power band and starting off and idleing but there’s a point if you hold the throttle right to where the power band would want to start kicking in it seems like it wants to run all stuttery

[@groundzero-979]

That’s pretty much what I had going on right before the powers and it would just be boggy and flat it was so annoying

[@groundzero-979]

That kit really did clean up a good bit of it there is still a little bit but no where near what it was

[@Roccodimauro3116]

I got a 22 150sx and I have a mid range sputter I messed around with the needle to no avail I also replaced the jet block gasket with the new jd one. I’m thinking my air screw is out of adjustment do you know what it could be?

[@groundzero-979]

Your most likely having the same issue I was dealing with no matter what I tried with the stock jet kit I literally had zero mid range and was boggy as hell. low speed and power band were 100% but no mid at all. the first video clip was the first ride out the dealership sounded awful. I will also say I gained a bit of power using that jd kit your stock 150 carb settings are needle 3rd clip from the top idle jet 37.5 main jet 540 idle air screw is 2 full turns out from a light seat the jd kit recommendations aren't even any where close to these settings but I have to ask have you had the bike since day one? is the bike stock? do you have any upgrades like pipe/silencer, reeds or run larger holes in the air box cover or any engine work? run race gas? have the power valves been messed with?

[@Roccodimauro3116]

So basically I bought my bike used so I bought it with a full fmf exhaust system (pipe and silencer) and people say ur supposed to rejet the carb so when I took my carb off to try to see the sputter it had a 480 main jet one step richer from stock (470) and my pilot was a stock 30 and my needle was on the 2nd from the top I moved that needle down to the third position and it ran even worse. And my bike was originally a 125 but the kid raced so he bored it to a 150 to make it faster and I have stock air box /cover and reeds. I don’t run race gas and I have no clue if the power valve was ever messed with. The only thing I haven’t check is reeds power valve and air screw. And also mine will sputter mid range and clear up at wide open throttle or al least close. Only does it when you in a lower gear when you crack the throttle.

[@groundzero-979]

Oh man that’s a lot going on the Settings that I listed before were straight from the manual for the stock 150. Honestly, I’ve never had this much issues with tuning a carb on all my KXs back in the day I used to only go up 2 jet sizes on the main jet and it was fine, unless I had head shaving, porting and polishing done pretty much raising the compression but I had an engine builder doing that stuff for me. if you don’t mind me asking what state you’re in so I can get an idea of your altitude I can list the JD jet settings and at least try to get you some kind of a starting point but will tell you 100% that the needles that came in at JD kit were completely tapered different than the stock ones

[@Roccodimauro3116]

So I live in Connecticut so I’m not really sure what the altitude and sea level would be but does the air screw on these mukuni carbs affect performance when riding because the bike runs rich it smokes a lot when it sputters and once it clears up it’s fine. The elevation for Connecticut is 500ft or 150m

[@groundzero-979]

@@Roccodimauro3116 the JD paper is calling for a 32.5 pilot jet the blue needle 2nd clip from the top 460 main jet would go up a size on the count of the pipe idle/air screw 1 3/4 turn from light seat I feel like that's good starting point only down side is that needle dose it ever smoke heavy all the time? do you ever see loss of oil? just wondering cause crank seals can also make the engine run lean it was just a thought

[@2StrokeSmoke701]

Do you have a link to the one you bought ?

[@groundzero-979]

I just went to snag the link and it’s no longer in stock if you’d like, I can find it from somewhere else?

[@Juicy_rpm]

isnt that the same jet kit as for husqvarna tc 125 2022?

[@Juicy_rpm]

also i have the same problem zero mid power,i mean not zero but shity, when i fully drive it its okay but when i let it stand for 3 minutes turned on and give it a throtle needs like 5 sec to come to hisghest rpm it just boging for like 3 sec

[@groundzero-979]

I’m not sure if it will fit the Husky on the packaging it says so 125SX 150SX an 125xc I’m not sure if it will cross over

[@groundzero-979]

@@Juicy_rpm that’s pretty much the same issues I was having a top was perfect bottom was good but the mid was boggy and sucked I did gain a good bit of power after re-jetting it money well spent.

[@groundzero-979]

At some point I’ll be switching to a lectron carb thay are just a bit pricey but I know they are worth it

[@nsty7075]

As long as your carb is mukini tmx38 it’s the same
