Hi Ken, thank you so much for these videos. Best thing on the internet for a KTM 950 carb. I’m quite sure my carbs are running rich. Dying at idle, sludgy looking spark plugs, smells rich, bad mpg. I replaced the plugs and that helped seemingly, but now it just varies more widely in its idle speed. Sometimes perfect, others very low and dies. According to the service manual, the fuel air mixture can only be adjusted with the carbs off (???!). Is there a good reason for this? Ultimately my question is, how do I diagnose and fix it running too rich? I have a carb kit arriving tomorrow, and a carb balancing tool arriving in a few days, so I’ll clean out the carbs and reassemble. Do I just set the mixture screws to 1 3/4 turns out and hope for the best? Any help is invaluable. In fact I’d be happy to send you money for a good step by step process breakdown. I want to learn to do this myself, and I’m willing to pay. Thanks 🙏

Dougie, never use a powered driver to work on carbs. Don't remove diaphragm if unnecessary. Always reference air/fuel position before removal.

Hi mate I’m trying to lower the front float to 3.5 at the mo mine is around 7mm by eye the rear carb float is fine but front is way to high any help would be appreciated

Hello Ken, very nice detailed explenation vids. Still i am confused about the ACV jet and the idle air jet position. Looks like you mention the ACV jet to be at the idle air jet (by the manual) position. Please help :)

Great series! At 6:27 you talk about the take-up shim. Just a few questions on that. - is that oem? - what function does it serve if not oem? - should it be used on both carbs or just one and if so, front or rear?

You are on the nail on do not lube the intake manifold boots 👍

Awesome video. WAW ! Fantastic series! But I've got a question. My 950 carbs have done 125.000km and the bike backfires a lot when closing the throttle. Almost sure it's the rear carb throttle valve axle that has too much play. A known problem, with almost no cure. So I'm thinking about disassembling the valve and the axle. Perhaps replace the axle with one from a front cylinder carb. But the screws that fix the valve to the axle have been peened. So they have to be ground away. Which is all very good, but how to I fix those screws afterwards? Some kind of Loctite? New screws that have to be peened too? All information is very welcome.

Hi, what a great vid!!!! I see you place the intake manifold clamps in such a way that you can reach them from the left. But I suppose it won't hurt of you place them in such a way that you can reach them from the right, right? Because when you do so, you can get the carbs out while leaving the left fuel reservoir in its place. Very handy when you want to check the mixture screws, or the membranes or something else.

What fuel tank is that on your exhaust

It's been quite some time but wonder how this ended up. Can you share an update? How is/was throttle response with the EFI, was there any performance benefit as well?

I'm in the market for a 950/990. I assume you'd recommend EFI over carb? Love your presentation style: "well that's interesting...I ran into this problem before." LMAO

What is the size of O-rings?

Can you share the resource for where you got the carb rebuild parts. With your videos it feels like I can do this if I can get the parts.

Where are you located?

An update to this build; The cells/packs that I used to make the original battery pack for this didn't work. The internal BMSs would trip at about 40A of pack current. I ended up building a pack out of Model 3 21700 cells and it totally rips. I had to turn the controller almost all the way down for the little kids, but when turned all the way to 11, it will haul around a 160lb guy and do wheelies!

Can you explain why you have the large shut-off switch? Is a on/off switch through the controller not adequate? I’m learning, so any info is appreciated! Thanks!

Where is the 280Z build. I'm watching that closely to assemble parts for N/A to turbo build. I love all your mods !

Many thank from the UK. Keep making videos

Can you get the emulsion tubes just above the main jet out of the carb body ? Can debris get into the internal passages? I’ve cleaned the carbs out several times, can’t see any debris anywhere. When starting it runs as if it’s on one cylinder, pops and bangs, only runs with choke on as soon as you try to open the throttle it cuts out. This bike is driving me mad !!! I’ve changed fuel pump and put additives in the fuel, just got the carbs off again, can’t see anything wrong. Any suggestions?

Looks great! I'd love see it in action! What model of Kelly controller did you use?

Do you have any idea what a normal fuel pressure should be on these bikes?

Any update on this one? I feel like I’m having a similar issue that’s tied to heat.

hi there....what handlebar do you wear on? is it wider than the original??Can you please tell the exact model of the handlebar???Thanks a lot....By the way very good job you have done there!!!!!

where the Mikuni DF52-136 Vacuum pump test with them been running one since 2008 been faultless one less electrical problem can't understand why people continuisly waste there time & money on electric pumps Desert , heat fuel vaporisation www.rottweilerperformance.com/insulation-line-per-foot/

I never understood the solid state controls of these pumps. Are they really any better? On my 3. Pump now. At about 135k km. I use OEM.

So, where are you located, I need you to straighten out my 950 carbs

Hello Ken, i can see you set the float bowl hight at 3.5mm , im confused after reading on ktm950.com , inside the HOW section it says the spec is 15mm.

I like a fool lost the small washer under my needle, any-chance anyone knows if you can get them separately or the radius and thickness please

Great videos!!! Cheers from Brazil! Can you help me with my jet set? Im using the set up by service manual - I have leo vince muffle uni pre filter em kn - what changes do you recomends? Petrol about 91ron elevation 1000meters above the sea and 15-35 celsius. Very thanks!!!

Amazing videos thanks a lot for your time!!!!

It's late Oct 2020 how is that Z coming brother ???

Just finding this build late Oct 2020

could you toss me a link for these o rings themselves? thanks for the great video! do you have a good uninstall carb video?

what the car do to make you change the fule rayl

Will these leaking cause the bike to run bad? My 950 adv started running poorly. It seemed like a fuel issue so I started looking at the carbs and fuel pump and found these to be leaking. I hope it’s what’s causing my bike to run poorly and not a bigger issue.

I'd part it out and spend the time on the turbo z 😎✌

Holy crap. I didn't know that was such a rust bucket.

Looks at 2 inch open pipe, oh yea it's gonna be loud! Sounded great !

Great video thank you.

did you ever dyno the bike?

hey man, you're back 😎. how's the z ?

Joe, 1.21 gigawatts

What clock speed does that run at?

I've also been trying to find an air leak that only shows up once the bike is warmed up.... any suggestions...

Perfect timing for me. I was about to replace the rubber boots that hold the carbs onto the cylinder, I'll replace those orings as well.

Your video came about a month late for me, did this exact job a while back! Ended up stripping one of the screws, Ontop of that I removed the Throttle Position Sensor instead of unplugging it. What a mission it was to reset that!

been looking at your L28 series tonight, it's been really helpful and this teally is the missing piece of my puzzle !!. you're a genious, keep up the good work !!!

hi ken can you help me to build mega squirt for audi 80 5 cylinder 7a engine

Awesome video, thank you. I watched a video from a company selling mods for the 950 and they show the grommet installation below the airbox, not above. I'll have to correct this on mine!

Hi Ken, I have a 950 2004 Adventure S. My carburator is leaking even the enging is off. I start the gasoline pump and I start to see speling gasoline from the back carburator. I just opend the air box and pull up the carburator and I see that is coming out gasoline. Do you have any idea about the problem? Could i t be a ring?
