Air filter replacement | ninja 400

In this video I will show you how to replace the air filter of kawasaki ninja 400

[@RevvedupK]

I can’t get the red clip back on the fuel line. How did you get it on?

[@turtle-ninja]

Try to push the pipe a little bit more. The force needed for the red clip is insignificant

[@stillshot2]

How often do you have to replace this? It's a lot more involved than my 1987 Honda lol

[@turtle-ninja]

It depends on the air quality. I do it every year. It is better to do it 2 times per year.

[@sksinha1]

This is a great bike, I love mine. But it is a major pain to work on. Kawasaki engineers were definitely trying to push you to the dealer LOL.

Zx6r 2024 is worse :}

Thanks for the video!

[@zebulonhull615]

Very good video very helpful. Maybe you could do a video of valve adjustment on the ninja 400

[@turtle-ninja]

Unfortunately I'm not skilled enough to make such video :( May be after an year or two. I will try to find a real mechanic to help with such videos.

Do we need to empty the tank b4 remove, bro?

[@turtle-ninja]

Nah. I have no issues with tank full on 80%. It is just heavier. Just keep the tank at level, dont rotate it like 90 degrees and you will be fine

[@ninjakensuperbike3933]

@@turtle-ninja i just worry that when we disconnect the fuel hose at the bottom tank. Why fuel is not coming out? Is there some kind of locking device or some how?

[@turtle-ninja]

Yes, there is a device that stops the fuel. Put towel or napkins under the hose. Dont hold the hose "almost disconnected". If you feel fuel on your hands, just pull the hose, so the device can block the fuel. You will lose 10ml of fuel, which is nothing :)

@@turtle-ninja thanks, bro.

[@lesmurray3306]

It's a whole lot safer and easier when you run the gas low enough for one flashing bar on the fuel gauge. A full tank rocks back and forth while you are in a compromising scenario.

[@AwkwardlyYou]

My filter is closer to the front wheel ninja 2023 ex400g

[@lesmurray3306]

The air filter is upside down! Throw it away and buy a real OEM. Those high flow filters may increase short term air intake but you risk letting trash inside and destroying your engine. It's not worth it.

[@Jayvetron]

It's installed correctly, the underside has a rim that sits in the airbox.

[@darshandarshan6111]

Bro it is ninja 400 not ninja 4000😅

[@turtle-ninja]

True :D

[@AlcatrazMeow]

you put the air filter different than how it was fitted before you removed it

[@turtle-ninja]

the new one is reusable K&N filter. It looks different than the paper ones (single use). If you plan to keep your bike for a few years - get a reusable, you will save $. OEM (single use) - 45$ HiFlo (single use) - 20$ k&n reusable - 60$ and wash&oil kit ~20, so total is 80$ you can do the math ;)

[@AlcatrazMeow]

@@turtle-ninja I meant you put it upside down...

[@turtle-ninja]

​@@AlcatrazMeow Hmmm I just double checked tha instructions - www.knfilters.com/ka-4018-replacement-air-filter The "flat side" is the one that should be on the top. Also on the upper side, near the hole for the bolt, there is "extra" plastic, that is preventing you from installing the filter upside-down. Please let me know if I'm wrong. !@#$ me if I'm wrong :D

[@Jayvetron]

It's installed correctly, the underside has a rim that prevents upside-down installation.
