Thank you sir I just completed my carburetor installed it and just flipped my bike on myself. All in all a good day. It couldn't have happened without you God bless the 250 nation
Today is the day, ladies and gents. I have watched this video many many times over the last year and today/tomorrow I'll be taking out my ninja's carburetor and getting her nice and clean. Wish me luck! And thank you so much for the vids, brother!
@@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😅.
@@anthoniomcguapo9097 replace the top cap and float bowl screws with stainless steel M4x14 (.7) hex head screws from home Depot to avoid stripping issues in the future (if you don't have JIS drivers).
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.
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.
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!
@@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.
Getting a 2009 today for 350$ just gotta clean carb . it will staty n run kinda ruff wen i stay on the gas soon as i let off itll die . just needs carb clean so easy bro
I did a carburetor cleaning on a Suzuki intruder. That was so much simpler than this. These Ninja units are extremely complex compared to other types. There sure is a lot going on in there. Makes you really appreciate how smart these Japanese engineers are. Amazing motorcycles!
Hey, that tip about setting the floats to "about 90 degrees" was incredibly helpful. Mine measured within spec when I did that, -.50 mm. Great tip, thank you!
DIYMR You are a wonderful communicator. This is so easy to understand and a pleasure to watch. All the things I have thought to be mysterious are now clearly understandable. I grew up reading technical manuals and writings never have I watched such easy flowing commentary. Great talking about tools and the importance a a good fitting screwdriver customized if needed. Thank you.
That was one of the best how to videos I have ever watched. Well done. Thanks for taking the time to put it together for us. I just completed my carb rebuild and it worked out great.
Great demonstration, my son took them apart and I couldn't figure out where the needle "bushings/guide" went. Thanks for showing the complete breakdown and reassembly of the carbs.
Dont forget to add the the float bowl gasket upon re-assmebly (at about 19:18) . Thanks again so much. I have watched it half a dozen times atleast. THE BEST
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.
Thank you for all the details in focus ( mostly) and no bullshit . Im just rebuilding an EL 250 , air box slides back real easy after the battery and CDI comes out and only a couple of bolts I think holds it in place .
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.
Big thanks for the how too .... Bike came right to life and runs perfect 2002 with 601 original miles sat for 18 years and I just took it for a ride here in Michigan November 23 2021 at a brisk 33 degrees
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.
My bike is running superbly after following you video instructions. Thank you for the advice on the fuel jet setting, surprisingly the jet setting on my right carb was set to 2 turns and the left carb was set at 3 1/4 turns after removing the jet pugs. By the way I used the machine screw to remove again very helpful advice.
I know you did this video on Ninja carb rebuilding, and another on removing the carbs years ago but wanted to let you know I found them to be two of the most helpful, no-nonsense RU-vid How-to videos I've ever watched on any subject! What your description didn't answer directly I was able to pick up from the video images. Thank you!
Dude thank you, I got a 2006 Ninja 250r on which I just can’t get the carbs to stop leaking. I ordered a carburetor rebuild kit that is coming tomorrow and I think your video will be a perfect repair guide!
awesome video! so hard to find any help for this bike. lots of valuable info here. i will definitely be checking out your other vids. thanks for your help.
Thanks for the video. I'll be doing this tomorrow. Just picked up a 2009 ninja 250 with 1260 miles on it and it doesn't idle or rev. Been sitting 6years with crumbed out fuel in it. Carbs have to be filthy.
@@jex8046 just finished her up the other day. Pilot jets completely clogged. Float height in right carb was 14 mm, left carb 19mm. Fired right up after cleaning carbs. New air filter and cleaned the air box. Put about 40 miles on it so far. Super fun bike to ride. Most fun bike I own. Waiting on Tyga exhaust I ordered for it
@@yellowveedub damn your lucky i got one 2 days ago and i have to wait to clean out the fuel tank its got a good solid inch of rust from fuel in the tank ive got to retake the carbs off to clean them again too
@@ihdandia try Tyga exhaust. They are in Thailand. Takes a while to get one. Mine took a few months. Afterwards I bought a dynojet jetting kit. Bike runs amazing
Thank you for this video saved me. So much money I bought a 2006 ninja 250 it has 256 miles on it last time it was started was 2015 they road it for lil bit sat 8 had to clean gas tank I checked carbs. N When I was cleaning them pice fell out your video help so much thank you
great video. just a point with regard to fitting the manifold boot clips at 25.45. I found it difficult to get the screw to engage in the small fixed bolt on the other side so before fitting the rubber boots on, I closed up the securing bands and slipped them over the boots. I was very happy that the boots went on so easily (silicone spray on them) and so much easier than the ones on a HONDA CX 650E.
I'm now cleaning up the carbs on a VTR 250 (Keihin VD10s) and i wish you had done a video on these showing step by step the procedure as you did here. You have a great video here.
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.
Thank you for a very instructive video. Only thing I would add for real beginners like myself is how important it is to put gaskets or some time of sealant on the carbs before screwing them back down. I got through the whole cleaning and installation and my carbs leaked. I know it was my fault because I didn't realize that I had missed a step.
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! Thanks again!
Thank you so much for your positive feedback... I'm glad I inspired you and if you have any questions just feel free to ask... hope you will subscribe to help me out. Good luck with the carburetor job!
Thank you so much, kind Sir! I've been dreading this labor, but your removal video and this one made it look so easy I am 100% confident now. Subscribed!
I just bought this bike and I got it to turn over with starter fluid for a spilt second I've cleaned the petcock it has gas the ignition igniter is good it has spark and has a good battery what else am I missing to get it to run
Nice job. Carbs out on my 88 this is very helpful..hopefully my cleaning will solve my hanging rpm and slow return to idle. Maybe vacuum leaks? In any case thanks for the lesson!
Excellent video. Only 3 problems! My bowl gaskets broke in the carb cleaner, I lost a small metal washer for the air/fuel thingy ma jiggy, andddd my floats are cracked and was filled with gas... yay me!
now you know how to work on most carbureted bikes. I knew my Triumph in and out and just realized that my ninja 250 uses the same kind of carburetor just a smaller version
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!
Thanks Mate, great demonstration. I have a 2010 kawasaki Ninja and it’s exactly the same process to follow. So anyone with an Ex250j 08-12. This will help you 👌
I need some advice my bike is a ex250j 2009 well idk why but it doesn’t want to go more then like 40 mph if I pull the throttle it sounds like it’s going fast but it’s not
Followed this video today. Will update this comment once I can test the bike to let you know how it went as i just finished installing carbs back on bike and adjusted cables as needed.
get an egg carton, tuna cans, empty yogurt or cottage cheese tubs, and keep your parts separated, clean, and so you don't loose them. A clean work space is a must. Berrymans chemtool in a spray can and paper towels are a must.
Thanks for this. The factory manual isn't as clear as I'd have hoped. This was very clear and informative. Edit- now I’ve put the bike back together, it doesn’t idle properly - either barely going, or too hard. Nothing in between. It takes a while to rev down afterwards too. Anyone know why it would be doing this?
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 !
Good video. worst part i found of this job is the actual fitting of carb back onto the engine. Its so frustrating and annoying that the engineers didnt allow the air box to be removed easily. I always say the same when working on quads. I didnt remove the intake boots like you as there old and may crack. them boots on the airbox are a rubbish design
I’m really hoping this works man, I tore it all apart n about to put it back, Gonna butterfly tune/adjust it 🙏🏽 never done this shit before but I pray it works
Thank you so much! I used this video to help me rebuild the carb on a 1996 ZZR250. Quick question though. When you tighten down the main jets, should the part that's contacted by your socket or wrench be flush with the body of the carb? For me it wouldn't. Im starting the bike tomorrow and ill let you know how it works!
