7:56 “Next thing you wanna do is get your caliper and put it to 17mm” …and then what? We didn’t actually do anything with them! I haven’t seen calipers used in any other carb videos so I have no idea what part of the carb you intended to measure or adjust.

[@josetrieu6717]

**dies on throttle*** Honestly I followed different video to rebuild the carb, but you literally saved me at 8:39. Holy crap did I need that.

[@addisondre8083]

i’ve got the same problem but the last all my damn screws are stripped

[@philippepemberton6001]

Yo, man. Idk if you still check this channel but I just watched your video and it’s super useful for me! Thank you so much!

[@MosWrld100]

I still do thank you for the nice comment and your welcome

[@alonepizza5270]

Great video, very thorough. My carb probably was never cleaned in 8 years lol. Only thing that was missed is to do a Carb Sync after. 👍

[@gerardmcconnon9155]

Great video But what are you measuring or adjusting with the vernier guage at 17mm

[@PLAYERSLAYER_22]

it is the pilot jet. but my question is how you get it to stay at 17mm without threadlock

[@MosWrld100]

who tf disliked my shit, your just mad you couldn't get your bike started

[@TheHamadanners]

Probly the "shotty" camera work but the struggle is real. #trolls its a good straight forward video

[@onefixitman]

If you want stiff wire for cleaning jets you can buy a wire brush with long brushes like for welding and pull a section of the wires out with pliers. Copper wire is too soft.

[@emmettturner9452]

Keep in mind that anything stiffer than the metals used in the carb are going to scratch it. That’s why people recommend brass wire.

[@onefixitman]

@@emmettturner9452 I am 50 years old and have been using stiff wire brush bristles on carburetors since I was 8 years old. It works and there have never been any issues. No disrespect. I am just telling you what I have used and it is cheap and readily available.

[@onefixitman]

@@emmettturner9452 No disrespect. I am just telling you what I have used and it is cheap

[@emmettturner9452]

@@onefixitman I wasn’t saying not to. Quite the opposite. :) Just saying to keep it in mind so you can choose the stiff wire brushes according to what they are made out of and what they will be used on. The same metal can be made more or less stiff by diameter but they will stay the same on the Mohs Hardness Scale.

[@Fuzi0nQc]

As a beginer rider with a 250, there's no way I'll do this sort of stuff anytime soon But pretty useful to know

[@SoybeanGravy]

Narcix 16 I’m a beginner rider as well, but in my year and a half of driving, I’ve done that much mechanical work on cars that this is nothing to me lol

[@kevinmatthews8980]

Hahhaahaah

[@damion3151]

Yeah that’s what I thought too but the shops never responded back to me and stated that I have a single carb. I have 2. So they were telling me false info and never got back to me with an invoice. Just said f it and started taking the bike apart to get to the carb. Fairly straightforward. Only hard part was getting the air box out imo.

[@ponylifestyle5995]

Should i replace the jets w stage 2 if i change to a k&n intake ???

[@laptopturbo]

Hey man I appreciate you making this video and sharing it.

[@MosWrld100]

Edwin Martinez thanks for watching if you liked the video don’t forget to subscribe I also will make more bike and car videos as the weather gets better here, it’s currently freezing with snow on the ground not really a good time to work on cars and bikes but ya

[@laptopturbo]

Mo’s World sick! I’ll look out for the new videos. I also have a 2008 ninja 250 she’s got a little over 5k miles and it might be time to clean the carb since I have to keep the choke slightly on because the bike would run at a very low rpm and then stall out when I’m stopped. I guess that’s why they went to fuel injectors for the newer ninjas

[@MosWrld100]

Edwin Martinez maybe try adjusting the idle rpm speed, once the bike is warmed up shut the choke all the way and adjust the idle by turning it. And put it around 1500, if that doesn’t work you can always try fuel system cleaner. I use an entire can of b12 chemtool even though it says use only a few cap fulls. But I use it before I go an a long ride so I put put the chemical fill up and ride until I have to fill up again it should clear up some minor stuff in the carbs. I don’t think it’s really necessary for you to take your carbs apart for something that small.

[@laptopturbo]

I’m going to give the fuel additive a try.

[@Nihilist_Adventure]

Because of this video I'm not buying a 250r. Haha thanks!

[@michaelw7932]

Dustin Stewart every bike that isn’t fuel injected requires this eventually

[@Anonymous-n7d]

Where does Ur clear(yellow) line go to on the bike?? I have the 2 lines that hook up to the fuel tank but then I have another line that I don't know where it goes and I think that's why the bike won't start,, if u use starting fluid it'll start right up..till it burns off the starting fluid then it dies .. Iv cracked the bowel screw on both carbs and both of them are getting gas and the floats are working as they should but I don't seem to be getting gas from the bowels into the combustion chamber,,the slides and diaphragms all look good carbs were cleaned out cause it sat in a shed for 10 yrs and they wouldn't get gas at all so I used wire and cleaned out the jets floats ect .. then they started getting gas and filling up the bowels but it still won't start or run on its own

[@kielvaninwegen6518]

You can "make" your own JIS phillips screwdriver by grinding down the tip by about a millimeter.

[@emmettturner9452]

Good tip. I’ve also heard drywall bits work better than Phillips.

[@sammartinez9113]

😂

[@jesserai]

wait, you didnt have to undo the airbox and push it to the back to get the carb out?

[@114wildfire]

Jesse Rai Didn't seem like it. Those 2 rubber things that go between the head and the carb, he removed that first. He shows you how he did it in vid

[@premonition-.5859]

I just take the seat off remove throttle and choke cables and push the carb down and out

[@LorenDavis]

Thanks for the JIS tip!

[@thc3704]

I'm working on a 04 250ninja right now and all I haf to do to remove the carbs was take the back and front boots off the carb and unhooked all the cables and hoses took off the tank and pulled the carb out the right side of the bike

[@JohnRoX]

I don’t wanna do it ; but now the bike won’t start at all

[@rafaelgonzalez-vt9hj]

min 1:22 that hose where it goes connected to ?? i just bought a bike like this and is missing a lots of parts also the carb only have one hose in the front yours have 2 . where the second hose goes connected ? mayby is the one im asking wheres go connected ? regards ,cool video ! help a lot

My jet only has one hole I see that yours has 3 mines a 2008 250 ninja is that normal ?

[@MosWrld100]

Kavin Truong ya it’s normal just make sure you clean each hole so that none of the holes are blocked and you can see through them

[@kavintruong8527]

ok just making sure, i only have one hole to clean, just wondering why youhad 3 lol thought i was missing something

[@shadowninjarider374]

@@kavintruong8527 07 was the last year they made the model he is working with. Plus there is no reason to remove the whole carb on an 07 or later model. You just need to remove the 2 top plates, remove boots and needle and clear and obstruction in your jets, open your drain screws on the bottom of carbs and spray carb cleaner through them. Close drain screw, replace boots , needle and top plates and your done.

[@ChaosBW]

You can get different jet kits which come with different holes/sizes

[@solomonpeace7468]

Nice job. Can you help with a link of where I can buy a working used Kawasaki GPx 250 carburetors. Can't get any here is Nigeria.

[@emmettturner9452]

You can probably find a forwarding service to buy from North America on eBay. They give you an American forwarding address. Of course, it cheaper/easier if you have a friend in America who can buy them and send them off to you in Nigeria.

[@kevinhummer7941]

Hey man what is that yellow tube coming out of the middle of the back of the carbs and where does the other end go to. I found thenother end just hanging inside my engine while trying to find the source of a coolant leak at first I thought that was it till I traced the tube back to the carb and have no idea where to connect the other end

[@Jessienesh]

It literally goes right there. It's a drainage tube

[@thearupert8538]

Where does the clearish-yellow hose go? Never saw it getting removed from anything, does it just suck air inside?

[@MosWrld100]

Thea Rupert that yellow hose is called the fuel overflow drain hose, it doesn’t go anywhere and doesn’t suck air in. It’s if the carbs take in too much gas it dumps it out the side of the bike so the carbs don’t choke them selves with gas, you don’t have to remove it or clean it I would just leave it because it could be annoying to get it back on . Unless your line got damaged but if it’s Intact don’t remove it.

[@MosWrld100]

Literally it’s a open hose that drains gas on the floor there’s no connection to it

[@thearupert8538]

Thanks for the quick response! Weird it just dumps gas out of the bike, one would think that would get corohsive.

[@thearupert8538]

Also, one more question: What did you end up using the caliper for?

[@MosWrld100]

Thea Rupert it just dumps it out the side of the bike to the floor this line only works if there’s a problem like you flooded the carbs or there’s too much gas inside the carbs and it can’t run so the carbs just dump it on the floor the yellow hose is long enough that it gets dumped near your right foot. If you look closely you’ll also have 2 more hoses near your right foot / rear break one is called the coolant overflow and the other one holds any oil that the crank case just got rid off these 3 hoses are routed near the floor and just get dumped on the floor. It’s not a big amount of fluid it’s just tiny little drops and you never notice it unless you take the carb off and forget to drain them and tilt the carb to the side gas will come out that hose

[@inesmoreira3091]

What os the yellow hose?

My ninja will only hit about 160kmh another bike content creator said my carbs was dirty. should it be fixed immediately? or can i wait a bit

[@MosWrld100]

If your ninja is a 250, 160kph is around the top speed nothing wrong with them. But if you have a higher cc bike and you feel like it’s lacking power you can run a fuel additive to clean the carbs and it might help

[@shescreamstates]

@@MosWrld100 my ninja 250 is capable of hitting 180 flat ground. my friend hit 180 the other day. but my bike isnt in the greatest shape. carbs probably havent been cleaned.

@@MosWrld100 whats a good fuel additive?

[@muhamadfachrurrozi8291]
