@@turk38922 there's a CRAP ton of screws stripped to all hell. Idk who my brother paid to do it before but they effed it up lol. Friend of mine suggested using a blow torch to heat up and try to knock loose any rust on these remaining few screws since I've had to resort to using pliers on the stripped screws. But I have doubts on his advice since there's gas and whatnot😅.

Just bought a 2009 Ninja 250.....I had no idea this was such a popular bike! Even though this bike has absolutely "ZERO" balls on the low end top end does not disappoint! Not to mention handling and flickability are amazing! Ive seen 100's of videos on this bike but Mr. DIY is by far the most user friendly for us old timers that like to fix and maintain our own bikes, cars, etc.... I would have NEVER thought to pull the factory plugs and pull and clean those pins. Although I have been working on engines of all sizes for DECADES having a place to go and take the guess work out of unfamiliar territory is fantastic! Thanks for your time and experience! GODSPEED!

Thank you brother! I just bought my first , FIRST EVER first, 250 - it’s a 91 EX2 or whatever - carburetor was in pieces apparently guy who owned it was gonna do exactly what you did but got to clown dickin around and just bought a whole new bike - a bigger one apparently- but I got a good deal- I paid 500 for it and I bought a whole new assembly on eBay should be here Wednesday - I am super stoked and watching you , you gave me the confidence I need to get this running! I don’t know shit about bikes other than my mustang sure attracts them! I’ve got an old 88 fox body and 2015 gt premium - seems like every time I’d go out I’d get a bike revvin it up at me so I’m eager to see what the entice was or why they do that , I know the 250 isn’t a street racer and to be honest I have too much to live for so racing ain’t happening - just will be cool to feel the breeze and ride - Really got cool vibes from ya - hope to meet people like you on the road when I get my wings to me!

@@KidNamedKuddy I bought a rebuild kit off of amazon. I highly recommend something like "20PCS Mini Tiny Micro HSS Twist Drill Bit Set 0.3mm-1.6mm" for cleaning jet holes. I got from ebay. Take a Photo of the carb if you might forget where things go when reassembling. And get a large work space to neatly lay everything out and plastic baggies to put in TINY parts. The 250 ninja starts and runs great now. I got all new carb screws from home depot also.

I got a 2010 Ninja 250 that sat up for a year outside. I had to clean the carburetor....clean the air filter...... change the spark plugs.... remove the petcock and drain all the gas.....replaced it with non ethanol fuel. It ran like a gem after all that.....before that it keep cutting off everytime I hit the throttle. It only ran on full choke but was limited to going 40 mph.

[@bigtimepimpin666]

You are an awesome help!!! I just bought a 2006 Ninja. I called five shops. They weren't too enthusiastic about doing this service. Some didn't even call me back. The ones that did wanted 250 to 300 bucks to clean the carburator. But I would have to take the bike to them. It doesnt run. The previous owner said if he left the bike standing around just a month, the carb would stick.

[@jamesrichardson1901]

Clear and thorough. Watched several vids on the 250 carbs and this is the best.

[@tomdanshin4176]

This was super helpful. Thanks! Particularly helpful was how to ensure needle jet is oriented and also the tip to remove the intake tubes before reattaching the carb to the air box - this provided some additional room that made the reassembly much easier.

[@jdhenckel2]

Thanks man! I left bad gas in my ninja and it would only run 40 mph at full choke. I followed this video, and now it works great. I had some difficulty to put the black tops on the carb at 20:15 the rubber kept pinching. The trick is to wiggle the top in a circular motion in order to tuck in the rubber diaphragm. The idle jets were hard to remove. I had to file down a screwdriver (like you did). I did not take apart the fuel pump or the air/gas mixture screws.

[@EverGrowSteve]

Bike was in storage for 6 years. Wouldn’t idle or run. I watched this video probably 5 times before attempting and did exactly as you did here including removing the aluminum plugs. Removed parts and cleaned as you described. Bike fired up and ran beautifully. In addition changed all fluids, oil/filter, coolant, brake fluid front and back. Thank you for this video! You did a great job of explaining.

[@ACommenterOnYouTube]

Mine sat for 3 yrs .... Same issue, cranked only on choke and died off choke and died with throttle on choke. Didnt know any better and took it to the shop, they charged me $390 to clean the carbs ... I was pissed. Ran good for yrs, bike sat again for another 2 yrs because of work and life. Same issue again with the clogged carb. This time i said nope, not sending this off for another $400 bill. So i took it apart myself and cleaned out the jets and all fuel passages. Put it back on and she fired up and idle'd like a kitten and she rode smooth ... Saved myself $400+

[@aaronwildman3652]

Very good video but two things I feel you missed one as you pointed out about halfway through but you addressed at the end is how the carburetor float needles love to leak the true proper way to test them is spend the money get yourself a mighty vac vacuum pump tool where after you reinstall your floats before you put the bowl cover on you can flip the carburetor upside down put a pound or two a vacuum on it and then let them sit and do a leak down test to make sure they truly close and you won't have a small amount of gas leaking through And other connected to the same area is getting a carburetor float height tool which measures how much gas actually sits in the carburetor bowl before the floats close off If your floats are too high you let too much gas in bike runs like crap if your floats are too low won't get enough gas runs like crap because it's running lean float height tool need to be made or buy a cheap one on eBay for 10 bucks but either way need to keep the float height set at 17 mm plus or minus 2 mm to get these carbs to run right.

[@user-xb1ht4py2v]

excellent, simple quick to-the-point video. One question: Do you need to 'synch' the carbs?

[@madislandguy]

Your warning to always tighten down parts as you install them is very important. I was messing with jets in some Keihin CR carbs on a GSXR1100 and somehow didn't tighten an air corrector jet because I was in a hurry. That jet got sucked into the engine at about 140 miles an hour and got caught between an intake valve and it's seat. It was not good.

[@gbongi1]

Thank you very much. What if the float height requires adjustment. How is that made? Also how did you make or where did you find the fuel bottle? Awesome vid!

[@captlarry-3525]

This guy knows these carbs, so even though I have been doing this 60 years, I am picking up some good tips specific to these carbs. I always read the markings on jets, because I want to know if somebody before me has done something stupid to "improve" on the engineering of the bike ! As he said, do not overlook removing the idle/air jets.. that is the tightest clearance most likely to clog place in any carburetor !

[@JorgeNX]

That drain hose that wasn't shown attached in the video (at 23:39), where does the other end connect to?

Thanks for this. The factory manual isn't as clear as I'd have hoped. This was very clear and informative.

[@davidmcdonald7060]

fantastic video! thanks for sharing it.

[@EvolvingNaturally]

I have a 2001 Ninja 250 - just rebuilt the carbs with new gaskets/jets etc. I have an issue I was trying to fix but this didn't work. So, it starts and idles then after a random moment it speeds up on idle to about 3-4000 rpm. I lower the idle with the adjuster then it goes to sub 1000 rpm. I then turn the idle back up to 1600 and it stays for a minute then jumps back to 3-4000. Also, I give it some revs to possibly get it to idle down and that's when it happens - gas pours from the carbs. If it's on the side stand, it's the left carb. The floats seem to be at 90 degrees and they are new gaskets. I am at a loss so I ordered a new Vacuum Petcock in case the diaphragm is sticking. Any thoughts would be appreciated! Matt P.S. Great video....I did sync the carbs and also the o-rings on the cross-over tubes are good. Aside from this it runs great except for the damage to my driveway...LOL

[@alds491]

I’m thinking that one float could possibly be cracked and fuel is inside it keeping the float pulled down and not allowing the needle to come up and seal the seat area. Also making it run the way it does maybe? Just my guess though. It’s all guesswork to me. You could take it out and swap them and see if the other side does it, or just replace both floats and try again. Not exactly sure though. Hope this might help.

[@alds491]

Or, where the float connects to the carb is dragging and hanging up keeping the float from sealing. Check the needle tip and carb seat area and make sure they are perfect and clean.

Also, I had a needle drag where it slides in and out of the carb. Had to clean those spots with a q-tip. And see if both floats are at the same level when all the way seated and all the way down.

Bought a used 250 to learn on and outgrew it quickly. Upon further inspection I realized the boots from the air box weren't hooked up and a previous owner had put the long bolt in the top hole. Any tips on how to fix the leak? I've got Teflon tape on the bolt threads but it's not perfect.
