Thanks for all of the great info . subbed .

Thank you for the support! Welcome to the club! 🤘

For around 15 cents I corrected my low RPM AFR surging, misfiring problem. I learned this after spending around $1000 on a power commander plus dyno tuning and still had the surging/misfiring problem. After studying EFI and buying an AFR gauge I had a smooth running engine and increased my MPG by 22%, The power commander is in my junk box. I bought the bike new and Yamaha customer service told me not to ride the bike in parks or shopping center parking lots so that the misfiring/jerking would not bother me. That is all they were willing to do for me. $13,000 wasted If one buys a lemon they own a lemon. It is their lemon.

[@andrewj9151]

Love mine. So far I think the 13t sprocket was the best bang for the buck.

[@jhmotorclub6916]

It totally changes the power delivery, per say. Glad you are enjoying the bike!

[@charlieholmes4278]

This was a great video looking to get one for my next bike

[@jhmotorclub6916]

It will be a blast! Thanks!

[@michaelcayer8358]

Well done & very straight-forward review. Friends that own this bike, like the KLX250 owners below, also cited the 13t Sprocket as the single best upgrade if they could only make or fund a single change. And while the KLX250 will stay on my short-list, my overall concern with the quantity of upgrades is the rapidly accumulating & total cost of implementing most, in not all, of these upgrades, relative to simply increasing your budget for a slightly bigger, better and definitely more powerful dual sport. It seems to simply make more financial sense to go that route versus subjecting yourself to not only the significant costs of all of these improvements, but also the time required to install them and most concerning of all, the risks to messing up the bike's overall functionality. We all have to draw the line somewhere.

[@jhmotorclub6916]

Thanks! You are certainly correct. Absolute great starter bike for building skills and even allows for rider growth to push the limits of the bike. However, it gets to a point where the bike's shortcomings come to light. I still wouldn't change the way I did it, because it is necessary to build skills on a "smaller" bike, rather than riding a "big" bike slow to learn the fundamentals

[@partygamer99]

awesome vid i get my 2021 klx250 soon from the dealer cant wait to start modding it

[@jhmotorclub6916]

Huge congrats! Working on the bike has been half the fun for me!

[@KingKo0]

That’s awesome! I’m picking mine up tomoro!

[@markaponte7057]

No way am I changing my seat it's perfect, but I'm a bike rider and I'm use to tiny hard seats so a motorcycle seat feels like a couch to me. Plus I love the Kawasaki branding on it. Great video keep up the good work.

[@redbilly5972]

Thanks Dude 🤙✌

[@jhmotorclub6916]

Sure thing!

[@eljuano28]

Solid list, my dude. My own opinion is pretty much the same except the order. First to last, my opinion is: tires, 14/51 gears, bars and bash-guards, stage one, (with MCM, 'cause BB is a bit rich for me,) fuel tank. I don't look at suspension dial in as an extra unless you're actually replacing components and I feel dialing in sag and dampening is just part of owning any bike. Seat would be nice, but it's more important on road than off unless you're idea of off is mostly easy fire roads. Clipping the ugly tail feathers is desirable, but I'm function over form, so not high on the list. I love the energy in this video, especially considering the mental toll of the injury. Great way to deal with that. See you in the next video.

[@jhmotorclub6916]

I try my best, have to keep the head up! No matter how you mod the bike, just as long as it suits your needs!

[@eljuano28]

Exactly.

[@seth567]

I sold my 2009 klx250sf but I still enjoy these videos man!

[@jhmotorclub6916]

Ah man, sad loss..... but I appreciate the continued support!

[@elcheekoful]

I literally just bought one. 2009 and everything.

[@wowguy3562]

I upgraded my foot pegs to IMS 273113 SuperStock pegs, they are about 2x as wide

[@elcheekoful]

Unfortunately these don't fit on my 09 kawasaki klx250s.

[@BikesNThings]

Number one for me is going to be barkbusters. If you're going to ride offroad regularly you need those bark busters. I've dropped my KLX at least a hundred times offroad and those things are worth their weight in gold. Skid plate is nice to have too. I got a 2018 like you, and I've definitely got some gripes :P . I went with the Renthal bars myself. Great video brother. Mirin' that seat.

[@jhmotorclub6916]

Thanks! It's a nice seat! Barkbusters are definitely nice! So many mods for only 5 spots lol.

[@szymonchalupka]

For me the best mods to be fast offroad are tyres, suspension and 13 tooth sprocket. Next ones are wider and stronger bar with some decent hand guards. And it's done. Moving from powerful roadbikes to KLX I really don't care if this thing has 18 or 24 horsepower. It is going to be slow anyway and this bike is meant to be like that. If I was lacking power I would get 2 stroke KTM or Husqvarna. But that's just my point of view.

[@jhmotorclub6916]

Valid point! Different perspectives bring on the need for different mods, just so long as you get the fun out of it! Sounds like you will have it setup well for off road

[@szymonchalupka]

@@jhmotorclub6916 indeed, it's great that you can upgrade this bike for any specific need that you have. And it will always be so much fun to own and ride. I traded my KTM 790 Duke for KLX 250 and couldn't be happier.

[@michaelbergwell]

Have you ever added heated grips to a bike? Just curious if it's worth it and how the install would go. Keep it up with awesome videos!

[@jhmotorclub6916]

I had them on my FZ-09. They are definitely worth it. After the first time I used them, I was sold. I did not install them myself, but they look pretty easy to install. And thanks!

[@Anamazing]

Noticed you're riding sand lake. Hi from Portland!

[@jhmotorclub6916]

I do ride there! I'm around the Washington Square area. Lots of good riding places within an hour of here!

[@danielson5045]

My man got so many subs!!

[@jhmotorclub6916]

All thanks to you all!

[@danielson5045]

JH Motor Club love your stuff man!

[@jhmotorclub6916]

@@danielson5045 I appreciate that, thanks!

[@xckxvxckxv]

What size front and rear wheels is your friend running with those dunlop tires?

[@tieoneon1614]

I did full FMF, programmer etc....Best money spent was Q4 slip on, O2 sensor delete and chip {16$} and 13t sprocket. Cycle Gear bar risers with stock bars rolled forward. AND keep that rear tire under 110-100 cuz the rotating mass sapped a lot of power. The chip acted like a fuel programmer, tricked ECU to send full fuel so no hesitation or backfire after the pipe installed. I hated the FMF Megabomb, it shifted the power to low rpm instead up mid/upper where it ripped.

[@jhmotorclub6916]

Good stuff, the Megabomb definitely produces more torque numbers. There's a setup for everyone!

[@rabidwookie606]

seat , tires, handlebars,skidplate, jet-exhaust. Vanity...fender eliminator, mirrors.

[@CalDeRosia]

Just subscribed right before this video. Maybe get rid of outro song? Great videos!!

[@jhmotorclub6916]

Thanks for the sub! Welcome to the club. Maybe next revamp, I have to support one of my favorite creators, itsjusta6!

[@tonycstech]

Can you be more specific what parts you bought ? Links will help.

[@CalDeRosia]

Just curious why did you decide to go with barkers exhaust? And commander fuel controller?

[@jhmotorclub6916]

Bill Blue always told me that the Barker system made good power, so I decided to try it out. The PCFC allows for easier dyno tuning, in comparison to the EJK.

[@marchelanonymous3633]

any idea about battery issues?it won't recharge the battery

[@randynbird5429]

Where did you get the black plastic above the headlight? I’m looking for some but I can’t find them anywhere.

[@jhmotorclub6916]

I just painted mine. Well, I did mine in bedliner coating. If you do this, be sure to scuff your plastics with some sandpaper to allow it to stick first. I did not do that because I wanted to keep my plastics clean lol. So, the coating comes off pretty easy if I hit something. I'm going to redo it and scuff the plastics before I coat them.

[@AdrenalineJay]

Can we get links to these items?

[@BRIANVANDUYN]

Haha green cast love it Haha

[@jhmotorclub6916]

Have to rep the Kawi green lol!

[@darkking_AO]

Did you derestrict your KLX?

[@CampCook12345]

Can you share what mirrors you have? I have a 2012 KLXs have appr 7000 klms on my D606 tires finally bought a new rear 2 days ago but could run my wore out one for the rest of this year if I had to the front is still ok for this year.

[@jhmotorclub6916]

I have Kawell bar end/under bar mirrors from Amazon

[@aidencoyne8278]

Can you reach out to me, I’m looking into building my bike but would like to ask you some questions. Nice build.

[@xsoobeastly3256]

since the bike comes lean from factory, would just rejetting or changing the mixture give better performance itself?

[@jhmotorclub6916]

Correct!

[@brianallen8752]

I haven't been able to find the KDX Snorkel can anyone tell me where I might find one

[@jhmotorclub6916]

I got it from Partzilla, part number: 14073-1577 www.partzilla.com/product/kawasaki/14073-1577

[@terryturk6813]

Kawi green cast..👍

[@jhmotorclub6916]

It was intentional lol! I figured it would match the bikes well

[@terryturk6813]

I noticed you got that new excaust..is your old on for sale..and that tst delete kit looks great on my bike.

[@terryturk6813]

I will buy you a new tst kit for your bike and have it sent to your house if you wanna trade

[@jhmotorclub6916]

Dang, I actually sold the FMF to my friend when I got the Barker, sorry. Otherwise, we definitely could have made something happen!

[@terryturk6813]

Its all good..I just hate to spend 350 on one..im fixing to buy my son a bike and that 350 could go along way on his bike..he's 11..he's gonna be the coolest kid on the block

[@brandoncastle109]

What is the top speed

[@markaponte7057]

Foot pegs?

[@mbaker7264]

What settings did you have on your ejk?

[@jhmotorclub6916]

I believe my best setup was 4 2 2 2 3 2 (G Y R GB YB RB), for the stock bore

[@edgarquianes7154]

Where you get the power comander, it’s ero only right ?

[@jhmotorclub6916]

It is "Euro", but really is the US controller with a Euro sticker on it. You can get it from Bike Design Benelux or Ebay, part number EFC17900E

[@akiedzul1853]

This bike use more fuel after change exhaust ?

[@jhmotorclub6916]

It did not after the exhaust, mainly just the big bore

[@redbilly5972]

Where did you get the skid plate?

[@jhmotorclub6916]

I got it from T-Rex Racing www.t-rex-racing.com/

[@krisfafrowicz7542]

Hey, just bought my klx. Im starting to modify it. Im looking all over for the power commander but they dont have it in for the KLX 250 just for the 110 and 140, any tips on this?

[@MaxMustermann-bm7qt]

On my 2013 or so, there are different chip tunings. If you pull the clutch the mapping is adjusted to give you ~3 more hp. Don’t know how it works. I let the shop do it.

[@MaxMustermann-bm7qt]

Don’t ever change the exhaust costs too much for a few hp. Just sell the thing if you got too good for it. Except of course if you enjoy the tuning. Have fun with the bike, solid 5/7! Ahh and when they activated the other map, they increased my rev limiter. That helps greatly highways.

[@dpiwu92]

Can u post links to ur stuff?

[@jhmotorclub6916]

I'm going to have to gather everything up. I'll get a list put together for sure

[@nickkozar9723]

Do you have any additional contact info for Bill Blue? The website appears to be down and I’m trying to get a 351 kit.

[@jhmotorclub6916]

I just checked, and it is up. It has his phone number, but good luck getting ahold of him. I tried contacting him for a piston, and cannot get an answer

[@nickkozar9723]

Can you please post a link to his website? For some reason I get an error message every time I try it.

[@mattnbiking8338]

What bar mirrors are those?

[@jhmotorclub6916]

Kawell bar end mirrors mounted straight to the bars, off of Amazon

[@basheadan2302]
