The other two countries in the same box as the US are CA (Canada) and CO (Columbia).

Ah, the CA got me. lol
i ended up finding a terminal in some spare wiring that fit, from a Ford harness of all things. wired the circuit and walla, fault is cleared after the OBD drive cycle to clear faults. i have a guy coming today wanting to buy it. fingers crossed, i want to sell it fast. tired of looking at it, hard not to ride it...

Been in contact with KawasakiBrad in Canada who steered me in the right direction. Just purchased a CA Kawasaki Purge Valve Bypass. https://kawasakibrad.com/shop/ols/products/purge-valve-bypass
So I'll get to drop another 1.5 lbs off of the Z400. After this mod it should weigh 348.5 lbs (158 KG) with a full tank.

Good job. Yeah seems like his plugs are the solution. I’ll look into it and see what the international freight options are like.

Kiwi, Think you and I are close in weight so we're on a mission to ride a light motorcycle. I tried to ride a buddies BMW F800GS, almost made it out of the parking lot and realized there was no way to touch the ground, traded right back before I did something stupid.
KawasakiBrad parts aren't cheap after shipping but are specialized. You've seen me wrestle with error codes so hopefully this will go smoothly.

Isn't that the same thing that TST sells?

That’s for the PAIR valve, not the Evap canister valve.

Oh, right. Thanks!

This is not a "how to" but just some pics from the Evap canister removal from a California Z400. I received a "California Kawasaki Purge Valve Bypass" from KawasakiBrad out of Canada. It was a matter of fiddling around and thinking about what would actually be removed and where the electric part plugs in. Kind of a Zen project. I left the tubes in place for now, the canister itself has only two tubes and no electronics. After the Purge Valve Bypass was installed, took it for a 10 mile ride around town and some freeway. The Z400 thinks it has a Evap Canister, No codes/errors!
A note: It did not trigger a code after I disconnected the tubes but left the stock valve on. But you know these 400s, with my luck the codes/errors would show up much later. So glad I bought the Purge Valve Bypass.

Nice work. Those hoses dont weigh anything much so may as well leave them if you want but I would block the one going to the throttle bodies so no crap gets in there.

Was wondering about that hose, I'll put a screw in the end. I referred to your photos but the Z (or CA) is different. Once the seats and covers were removed it all made sense, was glad I didn't have to private message you for advice, lol.

My girl did her Ninja 400 2018 EVAP canister deletion today using Smart Moto electronics sensor and plug. The procedure was super easy (99% of the time was spent to take the left fairing off). As said above in order for her to put the plug on the three way hose a removal of the tank and airbox was needed, so instead she put the plug here(see the red circle) leaving only a tiny hose (92192C). When she changes sparkplugs or delete her PAIR valve and airbox removal is needed, she may swap the plug to the three way hose. My point is that the delete requires only fairing removal. See the picture below and feel free to ask her if something is unclear on her insta @kotaronis

Her weight savings were ~ 682 grams. The kit weighs 3 grams. Photos and brief video of the steps you can see on this link - www.instagram.com/p/CKd0oaAHwXm

Good info. Always good to not have to remove the tank and airbox.

Quick update:
We had to plug the hose coming from the tank. The gas smell around the garage was a bit too much for one night. She will let me know if issues regarding the vacuum occur.

Hi all
First post, so forgive me if this has been answered. I have removed the evap canister and I’m wondering about the very short breather line that’s left running from the tank. I’ve done this for the time being, but should I get a longer line and route toward the ground like the overflow line?

Also just double checking this will do the trick to plug where it splits off under the tank, as opposed to the screw solution?

Thanks in advance

 

[Kiwi Rider]

What you've done with the breather hose looks perfectly acceptable as it's only vapor that will be exiting it.
I cant work out what you've capped the tee fitting with but it also looks good.

 

[moto_popo]

Thanks so much! @Kiwi Rider, the cap is a little rubber thing that was delivered with my block off plate for the AIS removal. I couldn’t work out what is was for but it worked for this so I’m stoked. Thanks again for the response

Hello guys, anyone that has plugged the vent line from the tank had vaccum problems? I believe there is another breather hole in the tank cap but dont know if it is tow-way or one-way. The kit from smartmoto electronics has 3 plugs, one for each hose, there should be no vaccum i believe. On my bike still with the evap system in hot days there is a lot of pressure in the tank, there is even a small whistle coming from the gas tank cap, i believe it breathes in and out gas vapor, when i open the cap it quickly blows all the pressure out and you can hear it very clearly. I havent done the delete yet but i am considering it.

Normal..on a warm sunny day I can hear mine 20 ft. away 🐉

Tried this today, with the intention of also taking care of the error code.
With just the removal of the left side fairing, I ended up leaving the purge line connected to the three-way joiner but removed and plugged it at the cannister end. This was because it looks like you can't access the joiner unless you have the tank and airbox off..

To prevent the error code, take a 680 ohm half watt resistor, and cut the legs so they're about 20 mm long. The legs can then be bent around and pushed into the purge valve socket. The resistor legs are a nice fit into the socket pins and should go in about a centimeter or so.

Job done, no purge valve error code :devil:

Hey Kwik, what year is your N4? I removed the evap canister on my 2021 and have tried your resistor solution for the error code with no luck. Wondering if it may not work on the newer model?

Hi, it's a 2018. Maybe they have changed it? That would be a pita.

Just some thoughts.. Was there already an error code/ or did you turn the keyswitch on before fitting the resistor? As if there was an existing error for the purge valve, or the resistor wasn't in place then that would trigger the error and it would need to be cleared by the usual methods (riding a special sequence, or plugging in a code scanner thingy). The resistor prevents any new instance of a purge valve error. Just to double check, the colours for a 680 ohm resistor are blue, grey, brown. then a gold band is a tolerance of 5%.

Would be a bummer if there is a change in the way the ecu checks for the valve!
