EJK Installation on the CRF250L

- This video shows me installing a Dobeck Performance Electronic Jet Kit to make sure the bike is running with an optimally rich mixture (having installed the FMF full pipe and carried out the air-box mod...).
Easy peasy just like you said. Thankfully being a crazy old witch I have small hands and was able to disconnect/connect the bobbins without any issues. OMG the difference it makes in fuel consumption and output from the Yoshi.
I actually found my fuel consumption got worse! Have you fiddled with the EJK settings?
TheMissendenFlyer Not yet. Was going to tune it over the weekend.
The more I see of the Honda the closer my bike gets to being on the market. Great video, thanks.
Thanks for the kind words BM - Surely the ideal solution is to have the little Honda as well as your current bike? Getting rid of perfectly good bikes is just wrong ;0)
Another great vid. PS all cable ties are reusable you just have to lift the gripper off with a small jewellers screwdriver or, provided you haven’t cut them short, you can use the end of the cable tie itself as it will slip under the gripper. It’s fiddly but does work.
Thanks, help a lot so I could install it by my self.
Interesting to see, that you tape away the negative cable from the battery, that's the way it should be! And great to see the improvements on the 250 Honda, i love the bike.
Just a precaution Joppie, I've learned the hard way with batteries over the years!! Cheers for watching, glad you like the bike.....TMF
I love your garage videos, would be good to see you do a garage tour
That would be one quick video! ....thanks for the kind words and the idea...all the best - TMF

HI TMF......another great video.......been watching your CRF ones as I'm hoping to pick one up soon !
Glad the old videos are getting a an airing! Cheers Daniel....
Another nice little 'how to', TMF. Nice balmy weather, today - I hope you got the chance to get out and record the impact of these mods on performance.
My father (in Norfolk) just told me it's a sunny day today too, 'fraid it's not here in South Bucks!! :0( Never the less I did still grab a 20 minute test ride...the bike is transformed from the stock machine with these mods. From the dealer the thing was gutless, now it's a beast! Money well spent and good fun playing with the bike too, sometimes simple is good (wouldn't dream of fiddling with my GS in the same way).....thanks for watching, all the best - TMF
Well....couldnt get my EJK unplugged....struggled like crazy in the 95 degree heat....but went and got my nephew with smaller hands and he was able to get it off and plug it in for me......got all green lights when I fired it up......they must have Japanese midgets or children putting these bikes together with tiiny hands.....lol....Im good to go now.....I actually unplugged the wrong thing that I thought was the injector up front and the black ejk end wouldnt fit on it and I struggled and struggled until I found another utube video that showed me I had unplugged the wrong thing.....lol......gosh this was much harder than I thought it was gonna be.....lol...it certainly was FIDDLEY, which is not an american expression, but I completely understand the meaning now.....lol
How are you getting on with it now Eric?
Thanks for the vid. I just got my EJK in the mail, this will be my first mod, I hope it improves performance. I guess next will be 13 T.
Paul Oake Good luck Paul - I actually found the EJK to make little/no difference to performance - the exhaust is the key thing - transforms the bike....good luck and enjoy!
Thank you very much.
Hi, I am really loving your vids, I have just bought a 2015 crf250l and the fuel bar started flashing for the first time at 90 miles. I have an ejk and air box filters sitting waiting until after the first service but now wondering if the tank range will be far too short because of the mods. Can you tell me what your range is now? I also have a 2012 speed triple but a dream collection like yours is just a pipe dream for me!(lol). Keep up the good work. Thanks Patrick.
Cheers Patrick - glad you are finding my videos of interest. I tend to fill my CRF at about 88 miles (low fuel bar flashing) but I suspect you could stretch to 110 if you like living on the edge! All the best - TMF
Another great video, thank you for sharing. Wondering about the fuel economy difference after the installation.... 😯
Top video, thanks for sharing. Really fancy a CRF250L to tinker with. Do yo recommend it as a do it all weekend road and green lane toy? What's the mileage like on a brimmed tank? Cheers.
Glad you approve - and yes I do recommend the bike as a do it all weekend and green lane toy (though depends on what you mean by do-it-all, 'cos it won't do a track day, cruise at high motorway speeds or carry loads of kit). If you want a fun ride, a great commuter, a toy to tinker with, something you can ride anywhere, then the little Honda is the bike for you!
Thank you so much really appreciate your videos, great quality and your work is done top notch 🙏🏻
Thank you sir!
Hello! I love your videos. Straightforward and easy to watch. May I know if I need to install an EJK if the only mods I did to my bike is just 13/42 sprockets? Thanks!
No, only really needed if you change out the exhaust...thanks for the kind words - TMF
Thank you for the quick reply! =)
Helpful vid. Made fitting my ejk easier. Cheers mate
You're welcome Ian!
Where can you buy the Electronc Jet Kit in the UK? great channel BTW bought my Royal Enfield 500 Chrome on the strength of your review. Paul
Nice one Paul! ....and I dunno, I got mine from the US website....
Lift the fuel tank and you get in to it much easier no?
Another great video, so temping to get one of these Hondas.
Go for it! They are fabulous fun and nice and simple to tinker with.....and cheap to buy, cheap to run....what's stopping you??!
Nice video, thanks for uploading. Does the controller not need to be somewhere more accessible so that you can change the settings via the yellow buttons or is it a case of set once and then forget?
Hi Nazaar - thanks for the kind words. It should be a case of "set and forget" and most installations I've seen have put the card in this location...it's neat and out of the way and doesn't tempt you to keep fiddling with it! Ride safe...TMF
I'm curious as to whether the EJK could increase your performance with the K&N filter and better flowing exhaust. You note below that you are "running with the stock settings the EJK comes pre-programmed with for the CRF with stage 2 mods". If you put the EJK into a higher performance mode, maybe you'd see some increases in performance? I'd be interested to know ...
P.S. Really enjoying your videos. Excellent work and the footage - especially the UK countryside - is outstanding. I'm from the US, but recently found your channel and can't stop watching. Gives me great memories of a trip to the UK a while ago. Thank you.
Thank you - and yes it could well be worth me fiddling around with the EJK settings, I'll make a note to do that in the slightly warmer weather (could be a video in it!)! Really pleased you're enjoying my efforts Paul, where in the US are you based?? All the best - TMF
I look forward to that video! I live in Portland, Oregon.
Great videos mate! Really enjoy them.
Thanks Henry - glad you approve :0)
Hi nice video !i install my new jet kit but I have a question...all jet kit come all ready programmed? I didn’t see u program yours...(my jek kit is power box from big gun ...pls let me know that that’s ...saludo from Mexico !!
I would imagine the Rally version...will have similar procedures...? .. guess we will find out eventually...
Yes I imagine so as it's basically the same engine....
Hi, you've inspired me and I've just bought a 2017 CRF250L and want to add FMF Q4, Megabomb and EJK. Really struggling to fine anyone in UK who sells the kit. I know you got yours shipped from US but wondered who you ordered from and if you were able to avoid import taxes by any means. Ta, Nick.
Did you ever do those mods? If so, how did you like? Exactly what I am trying to do to my bike.
Hi, great video, I have just bought the 2017 crf250l and would like to eventually get new exhausts and mod the airbox, want to buy the EJK first, will it still work with out the mods?
+Olly Colman Yes, it'll do no harm but probably won't give you any advantage either, I'd use the money to buy the exhaust first if it were me - makes a huge difference to the way the bike feels. Thanks for watching and for stopping by - TMF
That's good to know, saving for the exhaust but have the EJK arriving next week, going to do the airbox mods while I wait on the exhaust, could you recommend settings for EJK with just the airbox mods for now? Many thanks :)
Hi tmf I've done all the mods you have done on your crf 250 l .They have changed my bike dramatically (well pleased ). . My mot is due shortly do I need to put the bike back to stock or will it pass with the mods ? many thanks Jim
Did you see my MOT video?? ruclips.net/video/RLmIO7Z0qwM/видео.html mine passed no worries, I did put the standard number plate back on though....
Ok thanks I will give it a watch
Hi tmf about the mot I've watched the link was everything ok with the exhaust emissions and decibel levels as it did not show on the link cheers
nice bike i have stock
Thanks for your help, pretty straight forward once you see it :) My only problem is I cannot find anyone who ships it to Malta! :(
CRF's Only from the US.... Just ordered mine.
@@TheJAMTUB It's sold in lots of places.
Great video, I am about to install that same FMF slip on minus the power bomb header...will this EJK still come with the correct preset? Also, why did you remove the snorkel? Thanks!!
Hello, I have just purchased a 250 Rally and am wondering what is the make/type of stand you use on your 250L to supplement the centre stand? If you could help that would be appreciated? Many thanks & kind regards
Have u found the need to get a radiator guard yet? I found that black plastic one that comes with the bike, well, it really doesn't do anything lol.
Good job on the installs, you're a natural m8
No I've not done that yet, but now you mention it I will start to wonder no doubt!!! Thanks for the kind words, all the best - TMF
Thanks mate. Is it true after the header,pipe,airbox and ejk that a %30 increase in power is correct? How much do you think your mods have made?
Hi Jason - I've no idea actually how much more power the bike is making but there is no doubt these mods transform the bike, I would say at least a 30% improvement - the thing has gone from a damp squib to a thrill machine! Cheers for watching - all the best - TMF
No worries thanks mate I will be doing these mods one by one also. Just gotta buy the bike first lol😀
I was kinda wondering if you couldn't just hook it up to a laptop at Honda dealer and them program it for the FMF pipe? Would be a whole lot cheaper if it had been a carb jets are cheap lol
You possibly could get it on a dyno and tune that way but the EJK gives you flexibility and control....
It’s also means you can take it all back off when you sell it and recoup the dollar or half of it, or all of it if you already bought second hand maybe... €$¥$€£££
I'm curious to know what you do with those 5 LB purple weights. LOL! .... Please tell me they are for holding down a tarp or something! .. ;-) Just kidding. Keep up the good work.
...they're for holding down a tarp.... ;0)
Good answer!
Great video! You got yourself a new subscriber!
Welcome along! Thanks for the sub and apologies it took me so long to notice!!
TheMissendenFlyer No worries friend. Thanks for the welcome. I enjoy your videos a lot.
Any suggestion on EJK setting for CRF250L with FMF power core4 with Powerbomb header running on stock air filter and without air box mods ? Great vids. Thanks 👍
I just went with stock EJK settings for stage 2 mods - so no not really! Play around and see what works??
*Good stuff man*
DaytonaMisfits cheers dude!
So if i understood this right... You just have too plug it, and it does all the setting up by itself?
Pretty much yes!
@@TheMissendenFlyer seems like a great product
May I ask whats that bike in top left corner? 10:38 gold coloured wheels, double exhaust silencers. Looks great so thats why im asking 😀
Triumph Street Triple 675 ;)
@@gryndej thanks! 👍
Would you recommend the Ejk? As you said it made little or no difference to performance?
I have just put full fmf system on crf250l and haven't done the Airbox mod or bought an Ejk ...just wondering what you would recommend was worth it, cheers Charlie
Well I wouldn't recommend it from a performance enhancement point of view - with it's stock settings it made no noticeable difference for me. Of course I don't know what the long term prognosis would have been for my bike if I didn't use it - running the bike with a lean mix long term may not have done the engine any good, plus of course if I had been bothered to fiddle with the EJK settings maybe I would get a noticeable difference. On balance I would recommend it on engine protection alone, getting your air/fuel ratio correct is important for the longevity of your engine.....
+TheMissendenFlyer thanks, great videos..very helpful
Hi, do you know if this EJ okay kit would be any good for my Honda X 2021 as I’m getting pink problems as I open a throttle to overtake et cetera regards David May
I don't know I'm afraid - sorry
Great video!
Cheers Mark
Is it okay to ride my bike after installing the yoshi full exhaust set up I plan on buying the ejk but already have the system and want to put it on
Yes
Not much settings. I thought you were supposed to install it before starting up the engine as it says on their website. Maybe and older version idk. At least it says on tjeir website not to start the engine untill you turned on ignition and checked the lights flashing green, then afterwards it will blink red and green which should signal that you can start the engine. Well, what do i know.
Hi Mate. I have all the same mods as you have done, like many others. Not yet put them on as waiting for my EJK to turn up from the states. Can I ask what settings you are using on your EJK?
I'm just running with the stock settings the EJK comes pre-programmed with for the CRF with stage 2 mods.....
How you getting on with the EJK and FMF combo, especially the reliability of the EJK. Many thanks in advance.
+Mr Wobbleknocker Yes good I think, I've had no issues with reliability but then again I've not changed it from stock settings either, I just leave it doing its thing under the seat...what reliability issues have you heard then???
None. I'm just interested in all these add ons that people keep errrr adding onto there bikes. You'd think these new fuel injection bikes were good enough on there own without the need for tinkering with expensive fuel injection mods. Anyway, top vid!. P.S What bike are you going to road test next?.
+Mr Wobbleknocker Thanks for the kind words Mr W - not sure what's next, probably one of the new Triumph Classic range (once they're available) - looking forward to taking a first look at the NEC show in December.....
Hi I have bought a new 250 Rally! Are the Exhaust Filter and EJK mods worth doing? Did you notice a big improvement over cost?
Yes - especially the exhaust...a must do!
Have the same set up on mine. Do you need to unplug the oxygen sensor as mine is still connected?
I didn't mine...
I don't have a crf250l but I was wondering since you've done a full exhaust, does it make more power or just not run as rich? I've got a xj6n with a full exhaust and have been thinking about buying and EJK for it.
Chris Maxwell Hi Chris - I used to have an XJ6, great bike! I haven't noticed any power increase with the EJK to be fair, but with some fiddling I'm sure it would make a difference - if only to get the fuel mixture right for the country where you live/make it run less lean..do they do an EJK specifically for the XJ6 then???....cheers for watching/commenting - TMF
Yea it's a great bike, lots of grunt from stock and heaps of fun! I saw that they do sell one for the xj6, just uncertain if its completely needed. My bike has a full aftermarket exhaust but doesn't feel like its not running right or worse than it did with the stock exhaust system. Thanks for replying!
Cheers, Chris
I have an important question this time.....lol.....On the EJK website on the page that is specifically for the crf250l ejk settings, it refers to a Stage 1 modification and supplies the settings for that, but it doesnt say exactly what this stage 1 mod. is that I can find.....Is the stage 1 just the fmf, header, and air box mod, or is something else involved or not included.....?? Also I didnt see you changing your green, yellow, red settings at all, but the EJK website for stage 1 mods gives certain adjustments to enter into the ejk such as 2.0 or 1.5 or whatever....
+Eric Dealano Hi Eric, My understanding is "stage 1" mods are the FMF Header and tail end + the air-box mod and that the EJK is set up for these specifically tuned for the CRF 250L out of the box, if you buy the EJK version for the CRF 250L (but I'll look again at the website in case I'm wrong!).....all the best - TMF
+TheMissendenFlyer Thank you.....I did the air box mod, got the header and muffler on and got the EJK set up....had to up the yellow one notch to keep it from popping and I lowered the green by half a notch to help with fuel economy.....mine is running very good and im happy with it.....still not as much power as I was hoping for, but its just a 250, so Im pretty happy with it.......not sure it was all worth 700 bucks, but I had the money to spare, so I went for it.......I get alot of looks riding this bike around town.....very fun bike.....
Is the EJK necessary to make the bike run smoothly after the FMF exhaust?
Not to run smoothly but to optimise the air/fuel mixture, yes, it is required.....
If I install an after market exhaust and header then will my speedometer read different than it's supposed too?
No, why would it??? It's only if you change your sprockets (no of teeth) that that could become an issue...
Interesting mod,
Thanks...
any time man love your videos
Hi there. Once again I must ask. How much do these mods affect fuel mileage?
Stephen Arseneau See my other answer - maybe a 7-10% hit?? But the bike only sips fuel anyway....
Great Video well done
Thanks 👍
Doesn't the air box bottleneck further in? My logic is telling me it doesn't matter how big you make the initial box opening if the secondary opening is smaller (I've just got my first bike crf250 so figuring out what I actually need to do)
+The Hook err, yes you may be right....
Ok sweet I may just overlook that little mod for now then. Probably would make the bike sound a bit different with a larger initial intake though? I really don't know. Just got the bike and used your videos to inform my purchase, 250Ls are a great bike! Thanks!
I might have missed it, but what did you do with the ground wire? Sorry, I'm very new to motorcycles.
Connected to the negative terminal on the battery....although anywhere on the frame would do.
+TheMissendenFlyer Thank you very much! Love your series even though we have different bikes. Very helpful for a beginner.
I NEED HELP i drive mine daily but struggling to clean it :( i clean it 2/3times a week as the plebs havnt made a bike friendly salt for the roads just noticed the connector for the exhaust is like RUSTED the bike is just about 1yr old fk im stressed its so hard to maintain these bikes...do they expect us to take all the panells off everytime we clean!!
I need to know if this EJK is necessary or is it just nice to have...?? I have my Powerbomb, my fmf muffler, and my airbox mod. done....just didnt wanna spend the money on this thing if its not necessary......
Hi Eric, I believe it's necessary if you want to get the most out of your CRF after the mods - technically I don't think you'll do any serious harm to your machine if you don't fit one. Enjoy the bike and ride safe! - TMF
Seems to me you would need an ignition component to really take advantange of a Tune.
EJK vs bosterplug? which is a better? which is better value for money ?
Wow, with the price of that EJK "Electronic JET Kit" I think I'll stick to carbs where real jets are $6-$10. :)
Does this EJK controller increase the performance of a stock bike or is it just a waste of money on a completly stock bike?
Waste of money in my opinion, it really just serves to get the mixture right for a modded bike, in my case I didn't notice any difference having installed it (and they are relatively expensive gadgets) - if your bike is stock then the mixture will already be optimal ex-factory.
where did you get your fork guard graphics?
+Eric Matchett E-Bay
i put the fmf and the powerbomb on my bike yesterday and rode it......it shut off on me at a redlight when I revved the throttle.....did the bike get flooded (?) and will enstalling this EJK fix this.....I didnt want to have to use the EJK if I didnt have to to save money, but wont live very long with my bike shutting off on me at intersections.....
May help Eric, I have heard of this before and my bike quits on me for no reason sometimes (very rarely though) usually when rolling right off the throttle. Consensus is that the throttle idle control is set too low as stock...only happened to me a couple of times so I've not bothered trying to adjust.....
TheMissendenFlyer Will installing the EJK fix the problem or would I still need to adjust the idle speed.....? And thank you for your replies.....I appreciate it....
+Eric Dealano fitting the EJK didn't cure it for me :0(
Hi TMF, ive just modified my airbox and opted for the yoshimura system on my CRF250L and now looking to purchase an EJK. Where did you buy yours from? UK or USA? how much was it and how much import tax did you have to pay? Many thanks, Gaz
I bought mine via EJK and I seem to remember they directed me via a Dutch importer and I think that got around import tax - it was a while back though so my memory is sketchy. Think the EJK was around £200....
TheMissendenFlyer many thanks
What is the part number of the EJK you purchased for your CRF 250 L ?
No idea
Hi Mate i've got a 18 plate CRF 250l if i put the same header pipe & end can do i have to have the EJK on it ?
Nope
What about messing up the valves ?
do i use this on stock muffler and do i need to modify the airbox
Nope - you only need it if you have changed the exhaust and/or the air-box...if bike is stock you don't need to fiddle with the fuelling...
but if you do what will happened will it make her faster
Nothing - the fuelling is (or should be) bang on as it comes out of the factory, the EJK wouldn't need to do anything...
How would you describe how drastic the performance difference is between stock?
Didn’t notice any difference!
nice bike.
+Didoy Bacan Thank you!
How much this EJK will efect fuell economy ??
+Dusan Ignjatov Depends on the settings - as standard I guess I'm losing 5% of my fuel economy - all the best - TMF
so is it like a power commander?
Yes, pretty much....
What range do you get with the mods? Cheers!
About 90 miles......so a bit less
Hi do you know if the ejk would be ok for my Honda xadv
No I do t I’m afraid - I imagine not….
Where can I purchase EJK in uk
Nobody I’ve spoken to sells them ?
I dunno, I had to mail order mine from the US....
TheMissendenFlyer
Thanks, great Chanel.
Is it Alrite to install ejk without installing the after market exhaust ??
Yes, but I'm not sure why you would?
+TheMissendenFlyer I have ordered exhaust ejk and other mods..ejk has arrived but my fmf will be arriving a lil late that's the reason
+TheMissendenFlyer btw sir you make one of the finest video..the way you capture and explain all the installation is great hats off to you ...
+Rojen Pradhan ah I see, no problem at all then...sounds like some weekend projects await you!
+Rojen Pradhan Thank you very much, I'm glad you have found them of use :0)
How many HP do you have now? 30 oder more?
I don't know for sure as I've never dyno'd it....
Please answer me this. With all these mods to make the bike more powerful why didn't you just buy a bike with more power to start with?
It's just a bit of fun Glenn - there's all sorts of reason why the little Honda makes sense to buy over other more sprightly dirt bikes (long service intervals measured in 1000's miles not hours, road legal with lights and mirrors, cheap to purchase new, to name but 3)...besides, my other bikes are plenty more powerful if HP is all I'm after....cheers for watching and commenting, all the best - TMF
Thanks for answering me and now I understand a bit more. It's about the whole project and not just about the bike :) I ride a Yamaha TDM900 and vlog as TheDarlings2014. Me and the missus. I like your riding and flying vids. I started flying lessons but failed the medical due to a heart condition which prevents that. I've been riding bikes for 47 years now - can't wait till I have been riding for the big 50 years - lol
Stay safe and keep up the great work
Glenn Maxfield Cheers Glenn and thanks for your kind words - I shall check out your vids...all the best - TMF
How much power increase we are talking about here?
Not a lot - but noticeable....
@@TheMissendenFlyer Well for small bike like this any HP counts. One more question, how tall are You? Im 183cm and wonder will i "fit" on this bike?
I'm 5'8"
can I ask where you got your Fmf exhaust from and which is better megabomb or powerbomb?
cheers Mick.
I got the FMF direct from their website IIRC - The Megabomb is the one for low down power, the Powerbomb for better across the board grunt - so neither is better, just depends what you want....thanks for watching and for stopping by - TMF
you can install an iridium spark plug
it already have a NGK iridium spark plug installed when it comes from Honda

what is the top speed on the crf250l
I don't know officially but I have had an indicated 82mph out of mine.....but that's with all the mods, tucked in, and a following wind....speed machines they aint!
Stock bike, I can get to 75mph on flat road throttle full. Still stock....85mph slightly downhill tuckered down and drafting a truck. I am 6'1" 220lbs though.....
I just ordered the EJK and a Big Gun ECO muffler, and replacing the 40t rear sprocket with a 42t aluminum. Will try to update you top speed after that!
Killerclown360 OK awesome I just want a dual sport thank can go 70 when needed
Amazon sells reusable cable ties
...and sponges!
@@TheMissendenFlyer How would you secure DC wiring with sponges? I carry about six large reusable cable ties with me when I ride my motorcycle you never know when one might be handy.
I have a very high esteem for Honda engineers. I leave it ‘as is’. If I want more power I will buy another Honda.
What a comment. If you don't have anything nice to say.... In 2017 + models of the crf250l Honda engineers realized their mistake with their narrow head pipe and essentially did what he is accomplishing here. That is why the newer bikes have more power out of the box. Can get over 25% more power and the resulting reaponsiveness with new exhaust and a fuel controller. Check out the dyno vids. I don't deny Honda may have done this in a more polished and fuel effiecient way but I'd never make fun of a guy for doing it himself not wanting to throw money at a new bike every year.
Hey check out SR Moto this guy does everything you’ll ever need for your Honda CRF and a range of other models e.g

I wish you people would speak America I can hardly understand your accent and the second thing why the hell doesn’t Honda sell them with the improvements shocks light exhaust and all that other crap it needs
I don't have an accent - this is what English sounds like by the people who invented it.....
