How to install FMF Megabomb header. FMF Powercore 4, 12 oclock labs exhaust upgrade on 2016 WR250R
HTML-код
- Опубликовано: 7 апр 2018
- OK so I finally spent the money and did a rather large upgrade to the exhaust. This video shows a step by step install of the FMF Mega Bomb header, the FMF Powercore 4, and the 12 Oclock labs EXUP emulator on a 2016 WR250R. The EXUP emulator you need to get otherwise you will have error codes on from your computer. The EXUP emulator is a plug and play that fools your computer is all. I have to say I love this exhaust. It is quite loud tho. After riding it, I feel there is a bit of difference but I feel like the fuel commander needs to be adjusted for the acceleration, and full throttle modes. Stay tuned for the vid on tuning your fuel commander. The Stock exhaust also weighs substantially more then the FMF pipes. Otherwise I am quite happy. For questions or comments please leave below. Please like, share and subscribe. Thanks for watching.

You must be really happy with that exhaust tone now, sounds like a real bike and not a sewing machine lol. Nice video thankyou.
Thx Amped79
I love your new fmf exhaust man!!
Tango54th thx. It works well and sounds awesome. Thanks for watching.
Just bought a 2020 and bought this same setup. Thanks buddy great video. Liked and subbed pal
Awesome! They are great bikes! I usually try to answer all my comments on all my vids. Cheers!
Thanks a lot dude. Great video. I’m doing the same job, appreciate the step by step video! Choose 12oclock labs on the emulator too.
Glad to help. Cheers!
You probably noticed a big power difference as well here, good job, great looking bike!
Minimal notice in power compared to installing a fuel controller or a power commander. Gearing and fuel controller made the bike feel allot more torquey compared to the exhaust.
@@bigair0176 makes sense
Really nice video 📹 and thanks for the help 😊
thanks dude. No problem. glad to help. Cheers
Good videos I've watched most of yours and have close to the same mods
steven brooks thanks dude. Glad to help out the fellow wr250r owners out there. Cheers
Thanks for the video. Looks easy enough. My 2020 WR250R will be much happier...
Ya pretty basic if you have the tools for sure. Glad to help!
Thanks. I went to Hollister Hills today. My wr could use a little pep on the hills. I'll put the exhaust on first and share my thoughts. I'm also modifying the gearing, going with the stock 13 in the front and a 48 in the rear. Should be interesting....
You will like it much better then the stock 43t. I have 47 and it works well. I would really consider a fuel controller. It was the best power upgrade I have done to date.
@@bigair0176 Sounds good. Did you adjust your speedometer?
Not yet. It’s on my list to do hehe. I’m going to install a speed healer from 12 o’clock labs eventually
Great video! Thanks for posting. What tires do you have, they look nice.
Thanks Jimmy I started this channel to give back on small do it yourself tips. So thanks for watching my vids. The tires are stock bridgestones that come on the bike. I am going to upgrade the tires when the stock ones wear out. The wheels are also stock. The spokes have just blue spoke skins that make the bike a little more custom is all I have a small video showing them installed on my channel.
Great videos
Thanks Justin. Glad to help out the motorcycle community.
Excellent video...thanks👍🏻
Glad to help. It’s why i started this channel. Cheers.
Bigair01 just bought myself a new 2019 WR250R last weekend and picked up the same pipe and header at the same time...just gotta order that electronic piece right now so I can install it as well ...gonna watch your other vids now also...thanks for your help👍🏻
No problem. May I suggest you get a fuel controller when you put that exhaust on. These bikes are already lean from the factory. The fuel controller was the best bolt on power mod for sure. I put fuel controller on first and had to make some slight adjustments when I put the exhaust on.
Bigair01 will do , thanks man👍🏻
Great vid man. Definitely interested in honest thoughts of any power or range of power changes with new exhaust.thanks
Thanks Jorge. I definitely think the power commander mod was the most improvement so far. A lot of people do the power commander with the exhaust. But overall it is definite improvement over stock. I have to program my power commander as I feel it could pull harder at mid range to max rpm. The lower end torque is noticeable though. The powercore 4 is very loud. I wasn't expecting it to be that loud. But it doesn't sound like a sewing machine anymore haha. I love how there is no more jerkiness in the throttle anymore. The whole bike is a lot smoother to ride with all of the smog crap removed. My next mod I will be doing will be a 47 tooth rear sprocket. The 43 doesn't do a power wheelie, like my XR400 did hehe.
Jorge Gonzalez so I adjusted my acceleration mode and definitely helped my power curve. I adjusted the second setting on my WISECO fuel commander to 5.5 from 3. Noticed a better continuous pull. The rest were all in the recommended levels. I got my numbers from thumpertalk
Bigair01 thank you! Im gathering asmuch knowledge on 2 bikes. This one and the g310gs. I'll be purchasing in June. Thanks again.
Jorge Gonzalez also this bike easily does 140kmh in top gear with 43t rear sprocket. I will be doing a 47t rear sprocket to help with my low end torque soon
Bigair01 what time is it where u are.canada!?
great video ! just one question, I plan to buy an aftermarket slip-on, is it necessary to buy a fuel programmer also ?
The slip on doesn’t add a lot more power. I would say the fuel controller will add more and if your doing any unclogging a fuel controller is essential as you don’t want to lean the bike out to much
Just saw this video. Great help man! Where did you get the blue spoked wheels?
Thanks! Glad to help. Those are just spoke skins on the spokes. You can buy any Color you want from Amazon or eBay. I did a vid on them. If you look I have about 30 vids on my bike. I still have it and love the bike. Will prob do some more vids in future still. Cheers!
@@bigair0176 Ok great!! About to head to Alabama to pick one up. Lining up the mods. Thanks so much for your help. Makes life easier.
Great video. I am still debating on if I will do exaust/intake/tuner or not. Some say the EXUP system adds low end torque, how does the low end torque now feel since the EXUP is eliminated, more, less, same etc....
AJourneyOfYourSoul I would say if you do the power commander and air filter you gain the snappy torque you are probably looking for. I maybe gained a little more torque with the exhaust. But I think I need to tune my fuel commander to get some more out of it. But if your looking for torque I think a 47 or 48 rear sprocket will help out in the low end. With the 43 tooth it’s really tall and easy to do 120km+. But I want the torque and don’t care about top speed. That will be my next mod. Just have to decide on chain size which I think will be a regular 112link chain. But power commander and air filter was worth the upgrade for sure. Exhaust I just have to tune up better. I’ll keep ya posted
AJourneyOfYourSoul tuned second mode on my fuel commander and I am now happy for sure. Second setting went from a 3 to a 5.5. All other settings I left as they were already in range. I have the torque I want. Now just got to gear it better to use the torque range better. Cheers
Just got my exaust today powercore4 baby,along with ejk fuel programmer,seat concept seat,3 gallon ims tank,no toil air filter kit,yabbadabbadoooo!!!!
Right on. I still haven’t gotten the 3 gallon tank. But eventually I will! Hope my vids were helpful. I have vids on all of those accept the tank. Let me know what ya think of the upgrades after you ride it. Cheers
Install done I cant belive the difference!
@@scottmusgrave2417 sounds much better! It does add a tiny bit of mid range power but not enough to really notice it. But it won’t feel like your riding a sewing machine no more hehe
how much space do you have btw the pipe and the frame? Mine seems to be touching it very slightly which is causing the frame to become warm. i am assuming i need to make an adjustment to get it farther away from the frame?
Mine is pretty close. Hasn’t been an issue. It’s pretty much touching
I have the same setup on my 2018 WR250R except i have the Powerbomb header with the Powercore 4. When you start your bike and it's idle and sometimes when you give it gas throughout certain RPM ranges (like brapping it), do you hear what sounds like a vibrating sheet metal sound? i have ran mine and used gloves and tried to push and hold on things to see if it goes away and it doesn't. It's not a full time sound, just various revs and idle sometimes. I noticed its close to touching the bike so i'm going to loosen and see if I can get it further away. Nothing seems to rattle when its off and i knock on stuff with my hand. I didn't know if maybe it's because i didn't install the spark arrestor and i'm just hearing some baby pop sounds. This pipe is loud!!!! I love giving it hell to let cars know i'm near them!
Thanks Jason for the Comment. I don't have and sheet metal vibrating sounds. I definitely noticed my skid plate resonates and sometimes makes a tinny sound bit no vibration. I would suggest loosening all the bolts on the whole exhaust, and retighten them starting from the header bolts. Th instructions said to start at the header bolts so everything lined up properly especially the header to the head. I didn't use any silicone either with this install. I recheck my bolts often. I love this exhaust it certainly is loud tho. The spark arrester made it a bit quieter. not much tho. Hope the tip helps. Cheers
Bigair01 ok, so I need to go for a ride to be for sure, but loosening all exhaust bolts and moving silencer back a hair got it off the passenger peg area. I also did notice that since the exhaust pulses such a great amount of air on each exhaust “puff”, it does make a kind of air disturbance sound in the air 3 feet or so behind the bike. I hope this was a contact vibration and that I just fixed it. I did use very high temp gasket maker when sealing slip fit joint and where headed slid into cylinder. Also trying spark arrestor vs none.
I had that same pules. Good compression hehe. The Spark arrester reduced that puffing substantially.
Hey bigair
Trying to find the powercore 4 on fortnine that fits the wr250r, tried the parts numbers and it doesn't come up. Any suggestions. Looking for ship to northern Ontario.
Thanks
It looks like the part number may be different now. Research on google says it’s 044436 now. Every site I checked seemed to say out of stock. I checked eBay, amazon and fortnine. You could try Rocky Mountain atv or other websites. But I am wondering if they may also be out of stock. Possibly due to covid 19. Not sure what else to suggest. Maybe contact fmf directly and the can get one to you or point you in right direction. Sorry dude. Hopefully they restock soon.
I'm wondering how much better performance you got? Was it very noticeable?
Jamin Clardy the exhaust upgrade was minimal for performance compared to the fuel controller upgrade. I would say the exhaust just helped unclog the bike and made it a crisper power delivery meaning it wasn’t so jerky when you got on and off the throttle. I’m glad I did it for sure just wasn’t as huge a gain as you would think. I think you notice it, was just minimal. If it’s about money then do the fuel controller first. I did tho have to tune my fuel controller after I did my exhaust so it does give a little. Sounds way better then the stock sewing machine too. Hope that is helpful. Cheers
Did you get any backfiring at any point.. done day of you do the exhaust without fuel controller you might get backfiring.
Do you need the part from 12 o’clock labs to install the power core 4?
Evan Bell you need an emulator to plug in or it will throw an error code.
hey bigair, i did everything you have done to my wr250r. after everything is all done and said the bike is still pretty lame, should have got a 450. But anyways after I did everything now my kickstand kill switch does not work anymore. did you have that problem at all, when you stall the exhaust and the programmer.
ASMR TRENT I would love for more power for sure. After riding my friends xr400 then mine. Mine is more comfortable lighter and keeps up pretty good. I wish it had a lot more pull in the lower gears. I never had any issues with anything on my bike. Other then my speedo is out by a lot. I am currently working on a vid to fix that tho.
@@bigair0176 I can not thank you enough for your videos. It helped me do just about every mod you can do on the WR250R. Yes my speedo is out now too. It made the bike sound better and lighter, though. A little easier in the trails here in Colorado. These bikes do everything just ok, sometimes I feel the 450 would be the perfect bike, but hindsight is 20/20, and some people say the 450 is hard to handle in the trails, but much better on the street, where the 250 just feels very slow. Take care my friend.
@@ASMRTRENT just remember the wr is a much more maintenance free bike compared to all the 450’s. So it is a positive for sure.
Hey I tried to take the 2017 stock exhuast apart but than I foud that there is a sensor (oxygen sensor or something like that) on the front part of the pipe right after the butterfly valve you see in te video
My pipe never had any o2 sensor on the pipe. The euro version WR250R I guess has the O2 sensor. But I was reading on thumpertalk that guys were either having a bung welded in to thread in the o2 sensor on the new pipe. But I also read guys were leaving it unhooked and just tucked it away. Most of the posts said leaving it unhooked didn’t cause an error code. So my suggestion would be to tuck the wiring up out of the way, or have a welding shop weld in a stainless steel bung if it causes errors in your computer. My exhaust never had an O2 sensor to worry about. Hope this was helpful.
Bigair01 yeah its very helpfull hope it works. I will keep updating.
Thank you!
Sup brother nice video! Whats the 12 oclock device do? Do u have to have it to upgrade the exhaust? Thx
Effulgent Exterminating the exup emulator will fool your computer to think the exup system is still hooked up. The emulator is so you don’t get an error or engine light code. I can’t remember but I think there is another brand you can use for the emulator. I just used 12 o’clock labs cause I bought several electrical components from them and they work perfectly. I will be doing some more things in the future with 12 o’clock labs components. Just waiting for summer to be over hehe to do the projects over the winter. 12 o’clock labs were great and the parts where shipped within a few days to a week. Totally recommend them dude. Thanks for watching dude. Cheers
@@bigair0176 os that the same thing as the fmf programer?
Effulgent Exterminating yes it basically is same programmer as far as I can tell. It uses same lighting for each mode for programming as far as I know. I was going to do a programming video when I finally get a lapel microphone lol for my vids. Or maybe I will do a voice over. Bike is to loud to try and do video and talk the steps hehe
@@bigair0176 awesome man! I m picking up my wr250r tomorrow cant wait!
Nice! dude. Its a fun little bike. Make sure ya subscribe. All of my mods I have been totally happy with. I have a few more I want to do but waiting on cash and the winter for projects. Let me know what ya think of the bike and its progression from stock to modded. Cheers
Great video, except I never saw what you ended up doing with the wire connections you removed from the stock exhaust. I'm assuming you removed them completely from the bike. If so, I'd love to see that video.
Perry Wakefield my bike doesn’t have the wires the European version has. But I talked a little about the European version in my comments above. The only wires I have were the servo cables. I bought a 12 o’clock labs plugin to fool the computer. It is shown in the vid. Hope that helps.
I did a little more research and realized that I missed the part about the EXUP eliminator plug. I'll be ordering that soon. Thanks.
Ya you can get it from 12 oclock labs. I show how to install it in the video. Glad I can help. I made this channel to give back so glad I could inspire or help do it yourself. Cheers
Curious, four years later, you think it was worth it? I don't necessary like loud bikes but my WR must be running fairly lean, I'm at 1300m above sea level in AB. Mainly looking to fix the "surging when cold" issue.
Honestly I still love the bike for what it is. It mainly gets used as a commuter. Still running strong and zero issues other then changing oil and gas. Bike has been solid. I took a break off of modding it but it runs like a top!
@@bigair0176 that's the nice thing about the WRs! Love mine. Sold my first one for a KTM years ago. Biggest mistake. Back on a WR! I am going to try a programmer without modifying the exhaust just yet. PS is that a Oilers hat?!
@@ADVRider78 yea buddy. Love the mcdavid drai drai show. Frocking awesome haha.
@@ADVRider78 programmer was best mod I did. Gearing next
I have a 2018 wr250 looking to put on mega bomb we’re cami get the emulator your talking about I can’t seem to find it any were
12oclocklabs.com
Or you can also get it from srmoto.com
Can one take the decal off of this exhaust?
Larry Richelli yup. Little heat gun and should come right off
What power commander did you purchase? Thanks
I have a wiseco. If you look on my channel I have an install vid and also how to program it on my channel. Cheers!
What will the performance look like without the header?
The exhaust I noticed a little difference in throttle response. The mega bomb apparently affects the mid range acceleration but not enough that would be considered very noticeable. The best bolt on I have on my bike that has affected the power was the fuel controller then going from a 43t rear to 47t rear sprocket. I did fuel controller first and had to make some small adjustments when I did the exhaust to get rid of a flat spot in power curve. I have a lot of vids on my wr250r with mods and reviews on my channel
did you get rid of the AIS?
Noura Sali yes if you look on my channel I have done most of the mods to this bike.
I am debating a CRF450L or WR250R. Does the WR250R need a computer swap with the new exhaust or does it pop/backfire on de acceleration? I rode the CRF450L and really like the power, but it pops like hell without the Vortex ECU swap. I like the power vs my old YZ250F, but it certainly has EFI issues so the Vortex ECU with the Honda is must! It is very "jerky" throttled and also stalled on me twice in a short ride. So that is $700-800 on top of the price of the bike. So $1500 or so for exhaust and ECU. WR250R is less money and maintenance (from what I hear). I would do exhaust on the WR250R also....didn't know if the stock ECU will also cause bad popping.
The wr250r is lean from factory. That’s what usually causes the popping and backfiring in most bikes. The wr250r is no different. The wr250r just need a pcv or a fuel controller to add more fuel especially if you unclog the thing by putting exhaust and removing emmisions. It feels like a sewing machine stock but feels like it likes to rev once you do all the mods. I haven’t run the crf450l yet so not sure how much better it could be. I like the weight of the wr250r it feels very nimble. I did a review on my channel on all my mods plus a vid on things I don’t like about the wr250r. I think in total I have about 30 vids on the wr250r
@@bigair0176 what's a good fuel controller cost?
Jesse mine cost like 220 if memory serves me right. A dyno jet pcv is more money for sure. I bought a wiseco fuel controller.
Do we need to put the bike on dyno?
I should!
Got everything re installed and i went to start it and it wont turn over. It tries and then there's a a loud pop. Any ideas anyone?
Dead battery or low battery? Do you have a fuel controller?
@@bigair0176 i only did the slip on. Plan on getting a fuel controller once i do the header and intake. Its been cold by me in Wisconsin and i went back over everything and made sure all my connections were good. I gave it some gas when trying to start it again and it fired up. Got it figured out. Thanks though. Appreciate the response and the video. 👍👍
@@smallbobcat08o.g.47 good to hear. I would totally recommend the fuel controller of some kind. Fuel and gearing were the most dramatic increase in power output and torque. I’m sure you have seen a few of my vids already. I have about 30+ vids on mods I have done to mine. I will eventually have some more vids on my wr250r. Just waiting on availability of parts to be easier to purchase. Cheers. Hope you like the slip on.
do you think it will be useful for a wr450f
Exhausts for most part provide minimal performance upgrades. They will obviously sound better and allow for the motor to breathe better. That’s about it tho.
Fyi if you don't want to pay the $50 for the 12 labs emulator. You could pay $0.50 for 7.5K resistor
Wire it to the black and red and white and red wires.
Good to know. Thanks for info Brian.
I don’t care how it sounds I want to know the power increase of the pipe and muffler
Honestly it is a little bit compared to the fuel controller. What it does the most is get rid of the jerkiness when you let off the throttle, because of the removal of the smog shit. Check out my 27 vids on all the mods I have done to this bike. Don't forget to subscribe!. Hope that is helpful. Cheers
What's next Big Bore. It will never be a XR400 LOL Lets Ride!!!
Sounds sweat
Tool Man Taylor haha maybe one day make her a 310. I miss my xr400 for sure but this little beast is still fun to ride.
lol sewing machine
I know right. I guess some people like it quieter but I would rather be heard as well as seen on the road. Plus it sounds like a real bike with the fmf setup. Hehe. Oh well to each their own right.
Another sucker.
