[@mikeking7388]

Just bought a 23 sitting at 215lbs can’t believe how stiff it’s sprung sag set and racetech springs still in the boxes 13 hours on it now in a week. Sweet bike your videos helped with my decision on this one

[@DirtBikingwithDonnie]

Thanks for watching! Yeah, the stock valving is really stiff as well.

[@nuebien]

I always look forward to watching your vids. As a new rider and an old fart, I dig the info. It's appreciated.

[@DirtBikingwithDonnie]

Thanks! I appreciate the feedback, let me know what types of videos you want to see in the future. Thanks for watching and commenting.

[@slowride2222]

Thanks! Just about to pick mine up, this was just the kind of advice I needed. I hope you'll do one for the fan kit install when you get it as well.

[@DirtBikingwithDonnie]

Congrats on the new bike, you’ll love it. I was in a hurry the day I put my fan kit on and didn’t video it, but it’s so simple. Just a few screws and a prewired plug. Thanks for watching!

[@Envy2710]

Recently just bought an fx myself. Really enjoyed the video! Good stuff! 👍

[@DirtBikingwithDonnie]

Congrats on the new bike!

[@r4co1]

Mate, love your vids - watching from Australia. Keep em up!

[@DirtBikingwithDonnie]

Thank you!

[@justinsavs]

I don't even wait until I see the video to hit like. Love your videos!. I always do the Front HD tube, and Tubliss on the back. I love this setup also. I run slime on both front and back and never have had a pinch flat on the front or back ever.

[@DirtBikingwithDonnie]

That’s awesome! Yeah, tube in front tubliss in back is my favorite setup. Saw your hill climb to the K vid, great hill, looked cool. Thanks for watching.

[@Captain250FX]

What a great video! Your making me want a new FX! It’s been a long time since my bike looked that good. 😂 Still planning on going back to Alabama so I’ll have to make sure it’s before your race season starts.

[@DirtBikingwithDonnie]

Thanks for watching. I look forward to riding with you guys when you're back down south.

[@robrozek9265]

Great review right to the point and down to earth you have a ney scriber

[@DirtBikingwithDonnie]

Thanks for watching!

[@wyattbolyard711]

Bike looks great! I just got my 2021 Yz250fx around a month ago I put cycra wrap arounds, an asv clutch, the same odi grips you have on your, and some other little things still waiting for my graphics to come in though!

[@DirtBikingwithDonnie]

Thanks!

[@craigpeterson4779]

Nice bike!! Good info!!

[@markgunnison]

Looks like a nice setup. I got one of my employee/partners hooked on dirt riding. He is taking today off to go for his first ride on his new to him bike. I'm stuck working. He is also going to a place that is really easy with a guy on a quad. I should be able to ride with him before the official May 17th end of tax season.

[@DirtBikingwithDonnie]

That’s awesome. It’s always great to bring someone new into the sport!

[@TheLach111]

Great review - have you toyed with fork tube height? What height are you running for single track? Cheers

[@adzythepwcblokeinaustralia5467]

I have a Rekluse Radius CX auto clutch on my 2021 WR250F and a rear brake master cylinder and lever on the left hand side . This is very much an improvement that I cannot over emphasise how good it is to have perfect rear brake control at your fingertips. Australian WR250F come with the map ecu and wifi modules standard and I have been using a Keefer map and a Yamaha power map too with good results with a YZfx muffler.

[@DirtBikingwithDonnie]

You were ripping the single track in your recent video. Bike sounds great! Thanks for watching!

[@adzythepwcblokeinaustralia5467]

@@DirtBikingwithDonnie ,I’m enjoying your videos very much . I have ordered the airbox boot from the 2021 YZ250F which is an upgraded part that only the YZ version has which adds some power . I will let you know when it arrives what it does for performance. It’s cheap at $178 Au so why not try it .

[@shoefly757]

Did all the same mods except battery, clutch and air filter on my wife's 2021. Really want to do the no tool kit but I really like the funnel-web filters and there is no gromet where the screw would go through. Still waiting on the backordered GYTR seat and fan kit though.

[@jamaljackson9879]

Do no toil!! It’s absolutely surgical and 1/4 the price of others. I have one. Love it!! There is a grommet. It’s sealed.

[@johnchafin3817]

Your welcome...

[@eyeam33]

HI Thanks for posting this great Video, and the Parts list.. I have a YZ250fx 2022 do you this the black gas cap cover will fit..? Thanks Johnny

[@DirtBikingwithDonnie]

Yes, I have a friend who has the black cover on his 22. Thanks for watching!

[@oledad8505]

Thanks for all the links to the parts! Was curious where you got the black gas tank cover! Does it fit just like the 21 tank cover does? And what size are our stock bars? I got the 21 FX as well. Thanks!

[@DirtBikingwithDonnie]

The gas cap cover I noted in the video is the exact same part as the original, just black instead of blue, fits perfect. As far as I can tell the stock bars are Protaper SX Race bend. Congrats on your new bike.

[@rusty6314]

Excellent video Donnie, I've been in the market for a bike but haven't landed on anything just yet. I would compete in the C class myself single track conditions mostly. Do you know if the WR 250 is tuned differently than the fx?

[@DirtBikingwithDonnie]

Thanks for watching. The US version of the WR250F has a restricted airbox, restricted exhaust and the throttle is limited to 3/8 by a throttle stop screw. You also can't change the ignition and fuel mapping. Of course that can all be undone and opened up. The GYTR ECU is the most expensive part.

[@22YZ450FX]

@@DirtBikingwithDonnie I got the 2022 YZ450FX to avoid the WR restrictions because in Ohio I was able to register it as street legal with a few mods and get the full race bike performance without buying $ ^^up.

[@mrjawmaster5854]

Donnie, did you have to do anything special for the hand gaurds? I would assume that the ones you have on your link will fit my 2022? I know you had to modify your crossbar pad but didn't know if you had to drill our the throttle side hole? I watched one video that he said he had to do that.

[@DirtBikingwithDonnie]

Yes, the kit has everything you need. The yamaha stock bars have a weird size opening on the ends but the kit has the correct insert. I did modify the bar pad to fit over the clamps with a razor knife and trimmed the bar pad cover to fit as well. I did not need to drill anything, not sure what that is about. I ended up changing out my bars later because I wasn't crazy about the stock bar bend. When changing the bars I installed threaded bar inserts which I prefer over the expanding inserts. You can't use threaded bar inserts with the stock yamaha bars because of the unusually large opening on the bar ends.

[@paulf144]

How do you like the Seat Concepts seat? Is it that much better than stock?

[@tmlpony]

Hey try a Bridgestone m59 front and At81ex gummy rear,,you'll love that set up in the woods..

Thanks!

@dirtbikeing thank you brother. Great review. How’s charging with new battery?? Don’t you have to plug it in now??

[@DirtBikingwithDonnie]

The bike seems to keep it charged just fine. I do have a charger for lithium batteries but haven’t had to use it. Thanks for watching!

[@DirtBikingwithDonnie]

@@jamaljackson9879 8 months, 50 hours of ride time.

[@mrjawmaster5854]

Donnie, when you installed your cycra handguards did you have any trouble with the clutch side I noticed mine doesn't quite match up with the bracket that comes off the triple clamp.

[@DirtBikingwithDonnie]

Sounds like maybe your bars aren’t perfectly centered in the clamps.

[@andrewbecker3700]

Didn't think I'd like the SC comfort seat with my Acerbis 2.6 gal tank stickn out both sides. But it's actually much better than stock even though they use the same exact plastic base.

[@DirtBikingwithDonnie]

I really like mine too. Thanks for watching!

[@andrewbecker3700]

@@DirtBikingwithDonnie I'm thinkn bout ripn my stock seat apart and attempting to shape a chunk of extra firm foam to mimic the SC comfort shape, but slightly wider overall and a bit squarer in the back where the SC seat tapers too much for my liking. Then make my own 3 pc. cover out of garment leather. It'll be a good winter project.

[@AllanSmith859]

Do you know if my cycra pro bends on my yz250x will work on a fx

[@gregfolwell860]

I have the same bike, set up almost the exact same, what keefer maps are you running?

[@DirtBikingwithDonnie]

Keefer Hard Hitting most of the time. Occasionally the Keefer free feeling.

[@matiasmaldonado510]

I also have a 2021 250fx and I'm in love with it, however there are a few things that I would like to improve, and I wanted to ask you about it, I know the suspension is stiff, specially for a guy like me I'm 135 pounds without gear, I feel the bike stiff specially on technical trails when I have to go slow, I've been thinking on changing the springs for my weight but I started going to the track and the suspension works well there, I think if I soften the suspension, could not work well on the track, what you think? Also this bike doesn't turn sharp, have you done something about it?

[@carado1984]

Most men aren't 135 lbs so you can't expect it to be catered to you or 95% of the population is going to have way to soft suspension. Get a racetech revalve.

[@matiasmaldonado510]

@@carado1984 I'm not complaining about the bike being stiff, I know is too stiff for me because I'm too light, you're right most riders weight around 170 or more.

[@RAD_Family]

Did you install the radiator fan or are they coming for the factory with them now?

[@DirtBikingwithDonnie]

I installed it.

[@mrjawmaster5854]

Donnie, how tall are you? Im 6' and my 2022 feels a little tall. I havent got to ride it yet, but think in the woods it might be tall. I havent set the sag yet. I weigh 225. Will the suspension settle down some after riding for awhile?

[@DirtBikingwithDonnie]

I’m 5’10”. I think once you set sag you won’t have any issues.

[@nickolaskomsic6729]

I'm looking into buying one, What is wrong with it starting when buying it new? I've heard lots of people say it sucks but is it that bad, what happens?

[@DirtBikingwithDonnie]

Check out my first ride video here and I think it may answer your questions. kzbin.info/www/bejne/jmm5c5dnaciMiKM

[@22YZ450FX]

How's the Magura HYMEC Hydraulic Clutch Kit holding up? I'm interested in it.. IDK I rode my 2022 YZ450FX for 5hrs Monday and was ok but any longer and it'd wear me down.. I ended up with the comfort XL it's amazing!!

[@DirtBikingwithDonnie]

The Magura HYMEC is holding up very well. I have 80 hours on the bike since installing it and still loving it.

[@22YZ450FX]

@@DirtBikingwithDonnie Thanks! Do you ever have to bleed it or flush it? I've heard a lot of stories but they may have got clones who knows.

[@DirtBikingwithDonnie]

@@22YZ450FX I do bleed the system regularly, just like brakes, but not as often as I do brakes. Any hydraulic setup needs regular bleeding. The Magura bleeder kit makes it very easy.

@@DirtBikingwithDonnie Awesome! Thanks I'll be getting one before the season starts!

[@Fontainebleauify]

I can’t find the black padded part that covers the gas cap from this video? Anyone know where it can be purchased?

[@DirtBikingwithDonnie]

The part number is: BR9-2464E-10-00 I got mine from Rocky Mountain ATV MC. You have to look in the OEM section to find it. In 2020 Yamaha made a YZ250F in a gray color scheme. That is what you need to put into the lookup to see that part.

[@allanalasio4936]

Sproket combination

[@singletrackmarc819]

Where did u get the keifer maps at? I just got a 2020 yz250fx and have ridden 2 strokes my whole life and this hot starting issue has me ready to trade it for a 2 stroke

[@DirtBikingwithDonnie]

I got them from the Keefer website but I also show the maps on the screen at 3:59 in the video linked below. 2020 models have a service bulletin to adjust the CO setting in the ECU. You need to check with a dealer or previous owner to see if that has been done. kzbin.info/www/bejne/qXOTn62Kr7F2q9Esi=6HdyBSUcmJyrVd5J

[@singletrackmarc819]

@@DirtBikingwithDonnie thank you. It was already done on mine. Did it take you a while to adjust to the 4 stroke

[@DirtBikingwithDonnie]

@@singletrackmarc819 Yes, I was frustrated when I got my first yz250fx. It took me about 50 hours to get completely comfortable on it.

[@singletrackmarc819]

@DirtBikingwithDonnie OK good deal. Thank you for the replies. I have been riding for 20+ years and this is my first 4 stroke so it's a big change for me but every ride I am getting more comfortable on it.

[@yarbles_]

Why no tubliss on the front? Seems like it would be lighter.

[@DirtBikingwithDonnie]

I’ve tried it before and just like the feel of the uhd tube better for the front. Also, changing tires on front tubliss setup is challenging. Thanks for watching and commenting!

[@russelljohnson6829]

What specifically did you set your map to? I just bought a 2022 and the jerking/ engine braking is killing me at low speeds when I let off the throttle the bike wants to come to a stop there is no lugging at all how did you fix this ?

[@DirtBikingwithDonnie]

I use the Keefer Hard Hitting map and rarely change it. No map will solve the issue you're describing. The solution is slipping the clutch when you're at low speeds and low RPMs. Keep a finger on the clutch and think of your left hand as your "go" lever. Use the throttle only to dial in how much power you want. Doing that takes all the jerkiness out.

[@russelljohnson6829]

@@DirtBikingwithDonnie that's not what I wanted to here I just spent 10k, I'm gonna figure it out... port and polish, add fuel down low, idk somethings gotta work if not I'm trading this turd off and going back to a 2t

[@msparacino4191]

How is that battery once you’re riding for an hour lr two (hot start)?

[@DirtBikingwithDonnie]

I don’t have any issues starting hot or cold with the ag-801. It does take a couple of extra seconds to start if I stall it but that’s not battery related.

[@msparacino4191]

Yeah, the starting after stalling is the issue I was hoping this battery solved.

[@TheLach111]

Owners Manual helps - if you have have trouble starting after stall hold throttle wide open and turn over for a second, then start with no throttle (or slightly open)!
