- So in this vid I show you how to remove the vacuum solenoid that controls the flap on the top of your air box. This mod is a little nicer then drilling holes in your air box, and I can put it back on if it negatively affects performance or damages the bike. I already have a No Toil Air filter and WISECO Fuel Commander installed so this mod is perfect to allow more air in your engine. I would only recommend this mod with a Fuel commander so that you can adjust your fuel air mixture accordingly to get max performance. This mod cost absolutely nothing but your time. Check out my other mods done to this bike on my channel. Definitely like and subscribe to my channel to keep up to date on all my mods completed. If you have any questions or comments please note below. Thanks for watching.
thanks for posting your vids...one of your other ones helped me a lot this past weekend.
Greg anytime Greg. I enjoy helping people out. Saves spending tons of money on a mechanic. Cheers
Im glad you dont waste time vlogging and just get straight to it. thnx
Thanks for feedback! Cheers!
Thank you, very helpful!
Anytime!
I'd cut the top of the airbox wide open. My yz250 is wide open. As long as the fuel ratio is adjusted for more fresh air the only thing left is more frequent air filter cleaning. I think yamaha made the flapper to quiet air box noises.
Ya I think it was more of an emmisions crap that certainly not needed. But I get ya. I just didn’t want to destroy the air box in case I ever decide to sell and the new owner wants to put it back to stock hehe
@@bigair0176 less air is less fuel needed. So it would help with emissions to lean it out.
Another video!!$
I am curious why does everyone remove the vacuum valve. Just disconnect the hose. The valve is default open and is spring loaded. It should hold the flapper down.
Hey is this in Nanaimo? The roads look familiar but the footage was blurry so i'm not sure. Thanks for the vid btw.
Luke yes it’s Nanaimo. Thanks for feed back
@@bigair0176 Sweet! I bought a used WR250X recently. :)
Nice. It’s a fun little bike and easy to work on. I have about 29 vids on my channel on wr250r. I will have some more in the future. And my vid was blurry cause it was my cell phone. Lesson learned
Hey! My bike is completely stock and was thinking about doing this. Could you share your fuel programmer settings? I have a fmf fuel programmer, which I think is the same as all the other ones
It is the same. I have a vid on how to program your controller on my channel. My settings are on that video. It may be in the comments as well of that video. I got my settings from thumpertalk.
Why are you removing this part, it defaults to open position, just remove vacuum hose and plug it. Finished.

Haha if I only knew! Just wanted a little better air flow and now that it’s removed and taped open. it works great! One thing is for sure the bike was a lot more jerky with it working. Seemed to smooth out the jerkiness of on and off throttle!
Flapper is for noise emissions.
Hey mate, do you know of a decent LED Bulb for a wr250r? I'm totally clueless (no amazon in Australia) ty
Alex you can buy any H4 or 9003 LED bulb and it should work. You could probably buy the bulb at any auto parts store. Have you checked out my video of installing the bulb on my channel. I believe there are links in the description that you could view the bulb I bought. srmoto.com sells one as well but its quite expensive compared to amazon ones. Hope that was helpful for you bro. Cheers
hi there.
Sorry to say that my WR without AIS and without flapper has not passed the inspection because high Co2 levesl.
Do you know if installing again de AIS is enouth without flapper installation?
Stupid regulations here in EU.
I am not sure. I have never tried to reinstall mine.
The AIS helps burn any unburnt fuel that happens during sudden acceleration cutoff. The flapper could impact fuel ratios but extremely unlikely to be that.
What settings do you have on the commander? Do you happen to know the full sequence? Also what elevation are you at?
Blaine Leach hey thanks for watching. If you watch my how to program the fuel controller on my channel which is my latest vid. I am at sea level and I show my sequences on my controller on that vid. Off top of my head I can’t remember and am not home at the moment to look at my sheet. I can check when I get home later and tell ya. Cheers.
Is there any reason you can't just tape down the flap without removing the solenoid?
AdventureEng you could try but the selenoid is connected to the flap. Not sure how long it would hold. But the hole left on top will let more air in as well. Plus I didn’t have to drill any holes like some other guys are doing to get more air in. To many holes can let water in. In the end it’s up to you and what you feel comfortable with. I’ve had zero issues with not just this mod but all my mods done to the bike so far. Cheers
@@bigair0176 Thanks for the reply, I'll probably do this to my bike over the next week or so and use this video as a guide.
Again short sweet and to the point. Slowly copying every single mod you've done to your wr
Nice. Glad to help
hi
i tried that and my bike exploded all that was left was a few bent spokes
evan stockdale did you have a fuel commander? I do mention I wouldn’t do this mod without one
oh crap! i missed that part ..my bad
evan stockdale my guess if it blew up it was too lean. Sorta why the fuel commander is important to this mod. Sorry your motor blew up dude. That sucks.
being in canada, where did you get your No Toil Air Filter?
Gizake I apologize that I didn't put a link in the description. I have since corrected that with where you can buy it in Canada and USA. Here is the link for Canada amzn.to/2CRPHcc Cheers
@@bigair0176 Thank you so much.
NP let me know if the links worked and if is the right Air filter if you order it. I just entered the product number and that's what came up. Cheers.
Bigair01 should work fine, just ordered it. The reviews seem good, lots of other WR people have purchased it. Cheers
Royal distribution use to sell no toil.
Uni filters are way better products.
My no toil filter came apart.
bro i changed my airfilter and now my bike wont stay running what do i do
evan stockdale have you put in a fuel commander yet?
no i cleaned my air filter put it back in and it wont stay running as soon as i give gass it shuts off but it was fine before my air filter was changed please help
btw what is a fuel comander
You mentioned before that your bike blew up?...These bikes come stock already quite lean in fuel to air mixture to help with emissions and pollution. Doing this air box mod which is minor to what I have seen. Some guys go as far as removing the whole door. I wouldn't recommend that at all. It will allow a lot more dirt into your airbox. As I mention in this video I believe I mention it would be a good idea to do the Fuel commander as well. The fuel commander helps with adding more fuel to the mixture that burns in the cylinder. Doing the airbox mod and the air filter will really lean the bike out allot. This can cause over heating or obviously it sounds like its not running right due to, too much air and not enough fuel. A Fuel commander will help with supplying more Fuel to compensate for the more air. Let me know how it goes. Also something to think about is your elevation from sea level. If you live at a high elevation your oxygen levels are leaner also. All this can play with the performance of your bike. I would try the Fuel commander and see if that helps. Here is my fuel commander link below.
