How for a 2004 yz 250 use bike now

[@bradenriley9066]

Rocky Mountain should just come out with a monthly magazine.

[@googleuser1522]

$6k for that bike is amazing. Plus the fun of building it out.

[@jakeharthill1674]

Definitely a dream bike for me!!

[@rmatvmc]

Thanks Jake! It took a lot of time, effort and money but the bike came out exactly how I envisioned it would! A dream bike for sure! - Wes

[@danieljones8663]

did this build to a 2003 YZ250. Amazing to ride.

[@austinfn9318]

I put the steering stabalizer and bar combo on my yz 250. Not only does it look super cool I can now ride for as long as i want, reduced my arm pump allot and now i can haul but over any type of whoops with total confidence. Thanks for helping me with great setup wes!

[@rmatvmc]

Heck ya! Stoked to hear the tips helped you out. Most people don't understand how good the flexx bars really are until they try them. And you're right about those whoops, total confidence! Thanks for the comment.-Wes

[@kimatt6384]

Better than a brand new bike and less than a brand new bike, Personal opinion

[@rmatvmc]

Thanks @kimatt This is basically a brand new bike that is now completely setup for me and my style of riding. Plus it was a really fun project to work on that provided plenty of good memories. Thanks for checking it out! - Wes

[@bocaj628]

You guys just built my dream bike keep up the great videos and bike builds.

[@rmatvmc]

Thanks for watching! This bike is pretty sweet! Definitely a fun bike to rip and race and just look at! ha ha - Wes

[@aubreysweattii5700]

I just rebuilt/modded my 2016 YZ250x I bought three months back and it’s hands down the best bike I’ve raced out in the desert doing hare & hound/ all the District 37 desert series races. Stock the YZ250x was a great bike but I just put a big bore kit on it, full Pro Circuit suspension forks and rear shocks, Excel pro series black rims with heavy duty Spokes and galfer oversized wave rotors, Pro Taper fatty bars and triple clamps, IMS 3.2 gallon tank with dry break quick feel, ASV brake away levers and cables, pro taper aluminum throttle tube, D’Cor gripper seat cover, Pro Circuit works pipe and 296 spark arrestor, IMS bigger pegs, Maxxis ties, Works oversized radiator with braises and skid plate and that’s all I’ve done so far. Only a couple things left to do to it like front light bar setup,brake light, new kill switch setup, v-force reeds and a few other thing but the YZ250x is the best bike for your money!!

[@rmatvmc]

Sounds like a sweet bike! I'm still loving my yz250 almost "X". You have invested a lot into that bike and it works great for your type of riding which is awesome! What do you plan on powering your front light bar with? I've been doing some night rides with just a helmet light and battery pack setup which works awesome! - Wes

[@enduro-parts-aus]

defiantly agree blue bike black rims

[@rmatvmc]

There's nothin better! - Wes

[@rodmortensen5211]

I have never been disapointed with these videos , I'm rebuiding my 05 yz125 , and a 04 rm250 smoker, ....these bikes are in prime shape but I'm going to go factory .........lm 53 and getting into adventure ridding so I watch lots of your vids, .....thanks Wes for this video , I'm sure it was a bit of work,thanks! And Wes,that's a sick beard.👍

[@rmatvmc]

Ha ha! Thanks Rod. I usually get the other kind of "sick" comments on the beard! I'm now seeing the barber regularly and keeping her in tip top shape. It sounds like you've got a fun couple of projects on your hands. Congrats on finding some clean ones! Let us know if there's anything that we can help with and we'd love some pictures when you get them finished. Thanks for watching and following the channel. We love these bikes just as much as we love the adventure bikes. Check out our recent Battle Born Adventure Series if you haven't already. They are good for a watch or two. - Wes

[@mwwalsh133]

$600 base bike + $7,000+ in replacement parts, powder-coating, and accessories...

[@harhys]

Since the new models are coming out you could've bought a 2017 YZ250 for around the same price, sometimes less. Not sure about the YZ250X though.

[@MediumWolf227]

Harry _ but then it's still stock. The reason people go crazy with the two stroke builds is because the technology doesn't really change especially with yz's. That's why you hardly ever see "2005 crf250r build" because 4 stroke engine technology has come so far it'll never be competitive. you might as well build a bike that is custom tailored to you with the suspension/looks/power delivery etc. because by the time you do all that stuff to a 7000 dollar bike it'll owe you around 9 or 10. I think it's a cool idea.

[@bryanc447]

mwwalsh133 yeah with that money he could of bought a new yz250x but if he did it wouldnt of been as modified as this one this one is fully modified the x would be stock and if he put all the money on the new one it wouldnt defete the purpose that older bikes could become competivive with less money than a new one

[@foreshadow89]

KEEP IT STOCK AND KEEP UP ON THE MAINTENANCE LIKE THE MANUAL SAYS AND THERES NO REASON TO BUY REALLY ANYTHING ELSE... EXCEPT MAYBE SOME RIDING SKILLS

[@Gabrielsmusic]

choff60 most people could probably stay under 3k and be satisfied

[@OomLourens]

As a recent new Owner of a 2011 YZ250 I will definitely be taking some pointers during the transformation of my bike build over the next couple of months. Great video, thanks guys.

[@deadeyenic6833]

i wish there was shops like RM in Australia

[@Jack_Atcho]

DeadEyeNic Mx store

[@monstaxci7196]

thats who i use.

[@rayosteen4339]

That thing is sweet dude. I'm in the process of redoing and modernizing as much as possible a 99 cr250. 2 smokes are just so simple and absolutely riiiiiip!

[@boydclark7549]

Gorgeous creation well done, i love the ole steel framed YZees

[@rmatvmc]

Thanks Boyd! I am loving this thing! Lots of fun to ride and WAY more smiles per dollar compared to a new bike! :)

[@KSI_Revelations]

these bikes are amazing. I just bought a new 2017 YZ 250 2 stroke last year

[@chandlerchambers1114]

Disloyal Dashie how much different is a 2017 from like an 04-05?

[@peekingtom8337]

yall should post a vid on a walkthrough of the airbox conversion to fit the 2016 plastics. would love to do that to my yz250 but can't find any tutorial online to do so!

[@rmatvmc]

This is a fairly straight forward process. The most in-depth that it gets is the airbox and intake boot swap and with the YZ it's pretty easy. There is an allen bolt that clamps and holds the boot into the airbox. You access that from the top of the airbox. Once you remove that you can pull the boot from the old airbox and install it onto the new airbox in the same fashion. I did have to swap a couple of the plastic threaded clips from the old box to the new one but once I did that everything else is as easy as swapping the plastics. If you run into any questions on this feel free to comment and I'll get right back to you! - Wes

[@Jack_Atcho]

That thing is sick, love the old two-stroke builds. But the break calipers need to be coated in cerakote!

[@rmatvmc]

Thanks! It was a fun bike to build and is even better to ride! I cerakoted the right case cover and it turned out AWESOME! Thought about doing the calipers but didn't get the chance! I haven't decided if I want to add/ change anything else at this point. I'll keep it on the list! - Wes

[@akshooter762]

that's my bike! absolutely love it.....

[@rmatvmc]

Yamaha just did it right on the YZ250! Nice 04 by the way! Now all we need in an electric start model! - Wes

[@akshooter762]

man! electric start and this bike would be perfect! :) I'll have to post a new video of my bike, it look's way better ( from graphic's, lol ) my video's are how I bought it. I'm trying to figure out what I'm going to do about the brake's now, should I rebuild the Yamaha parts or look into Honda? Honda brake's are a poplular upgrade from what I've read? would love to hear what you guy's think/know about it...

[@jgrady7779]

Steel frame FTW.

[@rmatvmc]

Especially a black steel frame! Thanks for watching! - Wes

[@henrya1347]

I’m looking at purchasing a used Yz250, should I pay a little bit more and get a 2006+ or just get an older one?

[@norgepalm7315]

Henry Angell 06 if you can for sure

[@TheLoydal]

@@henrya1347 if you can find an 06 or up you can get away with running the forks and shock as they come from the factory. You may need to freshen them up, but you don't necessarily have to revalve them. The 2006 and up came with KYB SSS forks, they have speed sensitive damping. It makes a substantial difference. That's really the big difference between pre and post 2006.

[@fuckherrightinthepussy325]

Do you have a picture of your kick stand and were dix you get it ?!?

[@chrisvozza6530]

I wNted to see him rip it more! that looked like a bad ass spot for riding

[@ShaneAllen517]

Great video. Very informative on years and parts that can interchange love this build. More info than some of the other videos as far as how to put this bike together.

[@rmatvmc]

Thanks Daniel! There is so much that you can do with these bikes no matter what type of riding you are into. And with the bike staying fairly unchanged throughout the years it makes it even better for us riders! More interchangeable parts. Thanks for watching! - Wes

[@davezanin1863]

Awesome build!!! And pretty cheap under 5,500 great investment, Yamahas are bullet proof!!!

[@rmatvmc]

The bike has been solid since the rebuild! The only problem that I've had is trying to keep the pipe off all the rocks! - Wes

[@RelentlessCo]

When ordering graphics for the polisport restyle kit would I change my bike to a 2015 when ordering the graphics ? My bike is a 2005 250

[@rmatvmc]

Yes, that's correct. But let them know you have 05' lower fork guards and you'll be all set. Thanks

[@RelentlessCo]

Rocky Mountain ATV MC alright thanks for clearing that up

[@RelentlessCo]

We need more videos of this bike

[@rmatvmc]

I absolutely agree! Is there anything specific that you would like to see or any parts that you want to know more about? - Wes

[@bradyhood4786]

In all 6,000 is not that bad that a little less than a new bike and it's all fresh with aftermarket parts

[@jacobwhobrey1125]

Beautiful bike, love the steel frame yz’s. Guy looks to be a pretty dang good rider too!

[@kingmatthews5436]

What would you rather have? Cr Rm Kx Yz ? Saying this if the other bikes were still in production

[@rmatvmc]

You know what I would pick! Ha ha You know riding anything 2 stroke is going to be a good time! - Wes

[@therealbamachris1348]

Anymore two smoker is better than a slow stroke,,, but nothing is more reliable than a Yamaha YZ 2t.

[@JustinTwilley]

Hi what plastic kit is on this beast? Sorry if you said in the video I must have missed it.

[@rmatvmc]

Hi *JustAnR1!* Check it out here: www.rockymountainatvmc.com/Sales/770/2004-Yamaha-YZ250-Bike-Build We used the Yamaha OEM Plastic Conversion Kit. Thanks for watching.

[@dustinscheller7795]

That was a cool rear axle non spin part

[@googleuser1522]

Kind of a long shot, but do you guys ever let an outsider get involved in one of your bike builds? I live local to your payson location and would love to do a bike build with you guys.

[@vince5946]

I have a 2004 YZ 250 complete rebuild that I am doing the winter here in Michigan. Have you ever found a top triple clamp to replace the 04 fixed bar mount and update to the newer style bar mount? I would like to run the Mako bar mount on this build but want to maintain the KYB OC forks.

[@elimangone642]

Are those the stock plastics? The front fender looks newer

[@rmatvmc]

*Eli Mangone* No, it's a restyle plastic kit we sell on our website. Check them out! www.rockymountainatvmc.com/Sales/770/2004-Yamaha-YZ250-Bike-Build

[@charlesgutscher1923]

What are the pros and cons on their street frame bikes over the aluminum? I have an 01 yz250. I want to get an 02 or newer to build and I can't find much info on the steel vs aluminum frame YZs.

[@wrenchone5003]

that bikes sick !! good job there I like that one .

[@rmatvmc]

We think so too! Thanks for watching! - Wes

[@HeddleTown]

*Great build and awesome bike love the idea of older bikes new again!!* 👌

[@RelentlessCo]

HeddleTowns Enduro Ride when's a new video coming ?

[@HeddleTown]

Fr3ShPRiNC3 Try for Friday but very busy latly🤘

[@RelentlessCo]

HeddleTowns Enduro Ride yeah I understand , either way stay blessed 👌🏽🙏🏽

[@rmatvmc]

The YZ was the perfect bike to do it with! Still relevant and race-able! There is a ton of aftermarket parts for them and they are a blast to ride! I love competing on an older bike! - Wes

[@HeddleTown]

I agree Wes I started my Pro FMX career in the late 90's on a YZ250, that bike never let me down not even when hitting the first ever wood FMX ramps! 😬 lol

[@NICKDOG154]

awesome bike really digging the gas tank and the skid plate needed for my 03

[@riderrm2505]

Nice build👌

[@AnimalMother85]

I can't find the ignition cover on your website. Do you have a link?

[@rmatvmc]

Stay tuned! The ignition cover is expected to be in stock sometime in October. - Wes

[@juancadavid7741]

I have a question, the rear arm is the same at yz 2022?

[@SNL92100]

Ugh, i also picked up a bike that was maintained by a caveman, bent the cage on the air boot seal, Sand-injection! but those tires...did they shatter when you touched them?

[@rmatvmc]

Engines don't tend to last long with "sand-injection"! Ha ha I want to hang those old tires/ wheels up on the wall! To be honest I'd never personally seen a 20" wheel so I think it's awesome! I wanted to run the gold setup and looked for a 20" tire for a while but didn't have any luck and decided to throw on the Tusk Impacts! - Wes

[@jeremyeubanks2387]

really good episode. .. love the build

[@SwinginJohnson74]

Cool Vid. Thanks for sharing.

[@Stracham490]

what do you guys run for jets at elevation? going out west with mine and have no clue where to start? thanks in advance

[@nvmcrider8475]

What parts did you use to hold the CR style front brake line to the fork guard?

[@rmatvmc]

I drilled a couple holes in the guide hooks of the fork guard and secured it with zip ties. Works like a charm! - Wes

[@monte6amuels]

I’m building a 1990 cr 125 motor and throwing it inside a 2000 yz 250 rollin chasis will it look goofy ? I plan on mounting it as OEM as possible I want the bike to look like a normal 125.

[@Jordanshoecraveryo25]

Can’t find these handle bars anywhere

[@rmatvmc]

Here is a link www.rockymountainatvmc.com/Sales/2033/Fasst-Flexx-Handlebars?KZbin&Fasstflexxhandlebars&Description&KZbinvideos Thanks for watching! - Wes

[@AverageDaveVideos]

Wicked build!

[@georgesparrow100]

Where does the kit come from and what brand is it?? Thanks.

[@endurotruckererniedesjardins]

Super nice bike... there's lots of ways he could of brought the cost down on this build. Goes to show us old horses can still be great.

[@rmatvmc]

Thanks Ernie! Like I said this was just about every part and accessory that we carry for this thing! I'd like to say that everything that has been added serves a purpose but there are definitely some cheaper alternatives that would get the job done plenty good. Thanks for watching! - Wes

[@endurotruckererniedesjardins]

I had to go out a buy a 2018 yz250. I'm in ontario Canada and they go for 8200 bucks out the door with a super deal from trailside sports. Oversized fuel tank and flywheel weight 11oz are on my wish list. Buddy gave me a set of v force reeds and fmf fatty and 2.1 silencer. Just swaped the bars out for protaper evo woods high and broke my thumb same day working on my KENWORTH logging truck. So waiting for spring to ride now.

[@mudroost8040]

Still has a rubber frame and a turd of fork. '06 and up would have been a far better choice. Also is your 6 brand number with or without labor? Is that retail on the parts? Seems low to me.

[@ivanplaninsek6205]

Hi, i have an yz250 and i would make this too, but how did you rework the cylinder head? which part should be reworked?

[@tommyg3401]

sweet build

[@rmatvmc]

Thanks Tommy G!

[@michaelhoobler7520]

Tubeless tires ?? I know u said tubes do u have an opinion on this matter??

[@marchanselman]

Hey Wes I love the bike. I've got an '06 Rm250 that I've rebuilt very similar to yours, but more single track specific. We've got more than a lifetime of mountain trails out the door and not too many hare scrambles... I threw a Lectron Carb on to balance the seasonal elevations changes without having to re-jet, a fly wheel weight, gnarly pipe and TC2 silencer. One question I had for you - have you ever had any overheating issues running an oversized tank on slow single track with no fan? All the orange bikes run fans, but none of the Japanese bikes do - however they are out numbered 10-1 on the trails. Some friends that ride technical trails on YZ250Xs swear against oversized tanks for heat issues... I wondered if you've heard of this? Cheers

[@rmatvmc]

Hi Marc, thanks for the comment. It sounds like you have a sweet RM250! I'd love to see a picture. The lectron carbs are sweet. We've had a few guys add them onto bikes here and they perform flawlessly. We put one of the 2004 CR250 bike build as well. Not sure if you saw that video or not? kzbin.info/www/bejne/fWaWfop3fJKJoqs During the years that I've owned the YZ I have never had overheating issues. I've been on some gnarly trails and super slow technical riding and not had a problem. The oversized tank definitely blocks a little bit of the air coming through the rads and around the engine, but it hasn't been enough to make a difference. I also went to a high pressure rad cap and the Boyesen Supercooler Water Pump Cover and Impeller Kit to help avoid any issues out in the desert and on the trails. A high pressure cap is a great way to up the boiling point of your coolant and get around a lot of the overheating issues. Hope this helps! Let me know if you have more questions - Wes

[@brianjohnson8616]

Remember that the steal frame has some flex rather than the rigidity of the aluminum frame. One of the reasons why KTM still has not switched to aluminum frames.

[@rmatvmc]

No doubt! Flex in the frame can be a good thing, but they tend to wear out more quickly than a more rigid aluminum frame. Once again, there is no perfect dirt bike out there! You just need to find the one that best suites your needs. Thanks for watching! - Wes

[@christianadrian8903]

hi how i can buy a wide radio gears.for my yz 250 2000

[@rmatvmc]

www.rockymountainatvmc.com/Sales/770/2004-Yamaha-YZ250-Bike-Build Here's the link to our YZ250 Bike Build parts page where you can find and buy the YZ250 Wide Ratio Transmission Kit along with the other parts of this build. Thanks for watching! - Wes

[@takemechrome2291]

must be nice having an unlimited budget

[@whitebuff62]

Sweet build, just needs Tubliss! ;)

[@adventureforever5126]

Great video, enjoyed watching. My first MX-er was a 99 CR250 so this really took me back. Do you prefer the two strokes for enduro riding?

[@rmatvmc]

Thank you! I'm glad you enjoyed it! The CR250 was a great bike! It's a shame Honda doesn't make it anymore. I prefer a two stroke for really any type of riding (especially enduro)! I might be a little slower in some areas but overall I am having a better time while I'm on the 2T. - Wes

[@adventureforever5126]

Rocky Mountain ATV MC thanks Wes, I'm trying to decide what to buy next. Currently on a 14 WR450f and on the fence between 2 & 4 strokes. I think I'll try and have a ride of a few before making the decision. The lower weight of the two stroke is definitely a big appeal. 👍🏻

[@DavidMoormanSBarCa]

Iv'e got an old but dependable WR 200. I have no issue with tossing money at it, but my friends give me grief for it. I agree with your approach, I just need $5600.00 bucks to finish my bike!

[@rmatvmc]

Its a lot more fun to beat your buddies and all their newer bikes with a solid old bike that you have completely rebuilt yourself! Run what ya brung! - Wes

[@kdcustoms1272]

that's a badass bike... I got an 04 also. love it!

[@rmatvmc]

Haha. Thanks *KD Customs!* Long live the YZ250.

[@kdcustoms1272]

is it anyway for me to order that graphics kit?

[@waynesmith3712]

Love this build! I’m currently on my 4th yz build, I’m 10k gbp into it and can’t wait for it to haul ass, I’ve taken away some of your design so hopefully looks as good as yours 👍👍

[@tbank86q]

LOVE IT! im rocking an 02 KX250, pretty modded, very similar to this build. Super jealous of the yzx tranny kits that are now available, as i don't have that option. HooRah RM!

[@rmatvmc]

Thanks *Tbank86*. Glad you liked the build!

[@codeinelaced1639]

How'd you get graphics for it

[@rmatvmc]

Attack Graphics built them for me. You can build your own set of custom graphics on our website. www.rockymountainatvmc.com/Sales/51/Attack-Graphics?il_source=Home&il_medium=Promo-Attackgraphics If you are interested in these specific graphics let me know and I may be able to work something out. - Wes

[@jacksonenduro8232]

Will a 2015 plastics kit go straight onto an 03/04 yz250?

[@rmatvmc]

No it wont. You will want to purchase this kit from Polisport that includes a new 2015 Airbox. www.rockymountainatvmc.com/p/1044/69681/Polisport-MX-Restyling-Kit- . Then when these plastics are due for replacing, you'll be able to just buy the 2015 replica plastic kits from here on. Thanks

[@jacksonenduro8232]

Oh thanks guys!

[@pascalmangin6541]

Hi Sir, I'm interresting by the 2015 plastic kit for 03/04 YZ 250 but I wonder if we should not change the fuel tank?

[@pascalmangin6541]

I wonder if the locations of the screws of the new plastics (2015) coincide with the locations of the screws of the old fuel tank of 2004 ???? Or I need to change the fuel tanks for fitting with the plastic kit of 2015? Thanks a lot Sir

[@grant7411]

pascal mangin fuel tanks are the same 02- onwards

[@dylankesner6773]

Rad build!! You said you kept stock gearing minus the wr kit, so 1st gear is stock yz? I'm just wondering how first gear is in the tight, slow, rocky single track stuff as I might do a similar build and ride lots of the tight stuff. Keep it up!

[@rmatvmc]

Thanks Dylan! Yep! The final drive gearing is all stock so front sprocket is a 14 and rear is a 50 tooth. The transmission is where the different gearing comes in. I made my transmission a "wide ratio" transmission from the YZ250X. 1st and 2nd gear is still stock and these are both shared between the YZ250 and the YZ250X. The difference between the bikes comes in 3rd, 4th, and 5th gears. 3rd gear on the "X" model is actually slightly closer to second than the YZ250 and 4th and 5th are both taller than the YZ250 gearing. I've been riding this bike for a while now all all different kinds of terrain and the new setup has been awesome! I find myself riding in 3rd gear a lot. 1st has been just fine on all the single track that I ride even with it being the stock YZ250 setup. I haven't wanted to change anything yet. Do you have a YZ already? If so, what year is it? -Wes

[@whiskeyosos]

Rocky Mountain ATV MC I don't have 1 yet, I'm out here in CA so I'll probably get a 99-02 so I can still ride year round anywhere, after 02 they restricted riding in forests by the model year. I'm on an 2008 excr450 now, love the plate for dual sport action but the thing is not ideal in the tight stuff. I have been spoiled with the E button big time though! If I go this route, are there any critical difference from 99-02? Thanks!

[@Motor-City_Ben-Diesel]

Ok so the bike is a 2004, the plastics are a conversion kit for 2015, is the gas tank for a 04 or a 15

[@rmatvmc]

The 2004 and 2015 actually use the same part number for the gas tank. www.rockymountainatvmc.com/parts/acerbis-fuel-tank-p?v=667

[@DdDten]

Great video! What’s your thoughts on the lectron carb? I notice the more professional builds I see no lectron but tons on the more amateur builds. This is exactly what I’m after now. Rebuilding a YZ250 for woods hairscramble type riding. I haven’t ridden a two stoke in years and want a project as well. Only thing is the yz s are getting more expensive on Craigslist. I guess people know the value as many others are wanting a project build themselves.

[@rmatvmc]

Honestly, I think some riders still run a regular carb because you can do a little bit more custom jet work on it. However, I know guys that run the lectron on fully race-built motors and love them. The best part about a lectron is that its basically plug and play and you don't need to make any changes when you change in elevation. My friend has a 125 with a lectron and he can go from here in Utah where it's 5000-7000 feet of elevation and drive to California and ride at sea level and literally make zero changes and the bike runs awesome. You couldn't do that with a regular carb. Hope this helps.

[@DdDten]

Rocky Mountain ATV MC ya thanks helps tons I just hate messing with jetting going up and down elevation and call me under the rock but just stumbled across the lectron carb otherwise I just used jd jetting kit. Thanks again for the video I especially like it was geared for the trails and not just track because can’t afford to get hurt these days and the track seems to increase the chances and so the build related to me more.

[@dmadeitright]

What’s the song used at the beginning?

[@joztunes69]

If I keep my yz125K, it's an way older model, but would love to give it a face lift and make it look way newer

[@rmatvmc]

I think a 125 ripper would be an excellent bike to build! There isn't many things better than ripping around on a one deuce nickel! - Wes

[@dotdots2660]

its like you took and old dog off the street and gave it a new lease of life

[@rmatvmc]

...and a new hair cut! haha. Thanks *billy bilo*

[@dotdots2660]

haha yeah! it looks dope man

[@rmatvmc]

Appreciate the feedback *billy bilo*! Thanks for checking out our video

[@75_films]

Do a crf150rb build

[@pogoseth]

How much was the rebuild?

[@rmatvmc]

kzbin.info/www/bejne/eZS3k56aop50nJYm46s Enjoy! :) - Wes

[@DHolmquistDesigns]

Awesome bike! Buttt Why didn't you do the SSS fork conversion!? I did basically everything you did to a T with my 03 wide ratio tranny and everything but with 22mm triples and the SSS fork conversion professionally valved it was so much better than I could ever get the 03 forks to work. And after some time riding I added the ESR325 kit and man does it scream now, and pulls way better through those gaps in that wide ration tranny! Screw a new KTM, my bike may vibrate a bit more but it's dialed better in handling and performance and even with all the mods it's about $3500 cheaper that a stock KTM. A KTM300 with all the wanted mods/exhaust, head mod, guards, skid plate etc etc would prob set you back around $15000 all said and done and it still mite only be 'slightly' better if that!

[@nickbeall2353]

I have an Esr 325. How much does the Wr tranny cost about? My 03 suspension is dialed I wouldn't want to change mine.

[@stuckcamping]

Probably because the 2004 was the first year of he 48mm fork, vs 46mm of the earlier yzs

Can someone direct me to a Rocky mountain Engine rebuild? unless there isn't one. I have to rebuild my cr125r soon, and replace a crankcase. I have some doubts in my ability.

Thank you!

Hmm what year, those are not too bad (have done 92,94,96,01, all pretty much that same). Will need a few specialty tools, can be done without some but makes it a ton easier and safer. Watching a few video's never hurts but no replacement for the Honda Service Manual. Then it's just about organization of your parts as you pull them. Enjoy!

[@oherroprease207]

I just completely rebuilt my 2005 yz250 engine, and like you I was really nervous about taking on the task. I had done top ends but never anything past that. I went ahead and did it myself and it was not nearly as difficult as I thought it would be, just take pictures of everything as you go and put everything that goes together in labeled bags. If you really want to go the extra mile you could film the whole tear down so you can refer to it while rebuilding. But if you can do a top end job I'd say you should be able to do the bottom end as well. Also, you might be able to find videos of other people doing it on KZbin to help you through the process. Just make sure you get the proper tools so you don't have any problems! Case splitter, crank puller/installer, flywheel puller, clutch holding tool, etc.

[@mariomessinese9182]

bad ass bikes , my 02 is updated with sss and a few other mods, cheaper than a new 2017 .

[@rmatvmc]

No doubt! With the bike not changing much over the last decade or so it makes a lot of sense to keep the bike you have and set it up for your type of riding. I thought hard about doing the SSS conversion but couldn't wait any longer to start riding it and I am VERY pleased with my suspension that Precision Concept set up. Thanks for watching! - Wes

[@KruznwithKMAN]

I want to buy it

[@OGKILLa9365]

A new KTM 250exc or a 300exc comes already all setup. But I really like your YZ also, looks awesome

[@user-hn6ts4bc8o]

Where could I get a gas tank like that for my 05 yz250?

[@user-hn6ts4bc8o]

I also live in canada

[@ultralite85]

Love it!

[@Damianos980]

Awesome !!!

[@brianpalacios974]

Damn son how much did you spend on that thing? It looks bad ass all don't get me wrong but I feel with that much invested you can buy a brand new yz

[@rmatvmc]

Thanks for watching Brian and yes, I think it turned out awesome! I am under 6k total investment for this bike. kzbin.info/www/bejne/eZS3k56aop50nJYm46s MSRP on a brand new YZ250X is $7,499 so deciding between paying that for a completely stock bike or this for a bike completely rebuilt and setup with all my aftermarket goodies? I chose the '04 PS. I might be waiting until Yamaha releases a YZ250X with an easy button ha ha #fingerscrossed - Wes

I highly doubt pivot works manufactures bearings & seals, they most likely source them from a bearing company and have their name stamped on and resell them at an inflated price. I just go directly to a bearing supplier as they are much cheaper.

[@mrblack3480]

Getting parts for my yz250 is soo addicting and kinda dumb. Bought every part brand new, no used parts at all. Cost me like $3000 just to make it look good, think if I sell it in the future I will definitely be loosing a lot. As I seen fully custom yz250 for a lot cheaper then my build

Front disc guard needed 🙌

[@cliffcampbell8827]

Aside from the weight, what's the difference between the steel frame and the aluminum one? Some of the threads I've read are complaints about "the aluminum frame" but those posting those threads seem a tad (shall we say), biased. You know, haters of team blue, so I don't think I can get an honest and UNbiased opinion from them.

[@rmatvmc]

There is the weight factor, but it mostly comes down to chassis flex. The steel frames tend to flex more than aluminum. Everyone thinks that aluminum frames are just rigid and unforgiving but that isn't the case. A big part of chassis flex is the engine mounts, this is why you see so many teams running different mounts, to get more flex and a more forgiving set up. But aluminum frames are very good and yes, everyone is biased one way or the other. We have a rider here who was a very loyal KTM rider for many years. But once he rode the Honda 450RX, he couldn't believe how awesome the bike was and how much he loved it.

[@jasonwulff8341]

I like it when you do 2 stroke builds.You should do some more 2 stroke quads and see what you can do with an older bike like an 89 kx 250.

[@itsyaboizach159]

ok ok the bike is nice and all but bro of all fuel tanks why that one it makes the bike look abit weird like i love the bike and all but if it didnt have that tank on it it would be like a dream bike

[@willeypoboy6052]

Sick smoker!

[@justindwyer3832]

I find myself riding my 2003 yz250 woods set up more than my 2016 ktm350

[@jonnylong7927]

Hah. Any time you buy a bike more than about 3 years old, just expect to COMPLETELY rebuild the ENTIRE bike.

[@TheYamaha109]

looking to do the exact same thing with a 05 yz125 sorry but I totally stole some ideas from this haha

[@rmatvmc]

That is what we want to hear *BOSTON IRISH GARAGE Wrentham MA!*
