2003 KX250 Build Breakdown!! With All The Mods!!

[@interstellaraxeman4468]

This is a great video to watch for purposes of refitting some components that as can be seen, are compatible over the model years. I had recently acquired a 2003 KX250-M1 that has never seen the filth of this earth as it is destined to do. The bike was set-up, jetted for the expansion chamber selected, but never broken in, and the owner went out for "one last ride" on their old bike,...and had a mishap that resulted in that KX being frozen in a time warp for SEVENTEEN YEARS, never even ridden. I had to give it a home, but its display days are over, I thought about keeping it like that, but that thought lasted about a week. In that 17 years the bike sat, a LOT has changed, so it is quite helpful to see the compatibility aspect with minor adjustments to make the front suspension work out here. The advice to always invest in a top end examination and replace the basics to have a solid starting point with a newly obtained bike is important to pay attention to as mentioned in the video. Even though this bike was never operated more than a few minutes, it is getting torn down and having new seals, bearings, rings, piston, all the usual parts that would be in the first recommended changes of those parts at the hours of operation mark for them, but only because of any potential compromise from remaining dormant for so long. Plus, I need to know its good to go,....so I`m very appreciative you said that, and made this video. No pun, but that "sealed" the deal for me. If that catastrophic top end fail could happen, doing what I can to be proactive with such a scarce relic is a healthy workout for familiarization of the internals,... and its my first KX250. So just because it is a brand new, zero-hour use bike is not a good enough reason to skip over this procedure,... ( sometimes we need to hear a reminder, so your experience is not for nothing, I`m listening to that advice, because you`re right) I will be looking at straight up swapping out forks and rear suspension with something from this decade,.... What can I say?, some people REALLY WANT a Kawasaki 2 stroke. I wish Kawasaki did too,.... Thanks for the video.

Yeah no problem!! Glad you appreciated the video!!

[@shad3128]

Same shit happened to mine, when i bought it on craigslist the top end exploded and ruined the bottom end. Tore the entire back down and restored it back to OEM. Couldn't be happier with it now but it was a hell of a project 🤣 nice job on yours!!

[@jtmarshall]

Nice video man! Especially covering the fork change... I have 2004 ive had since 2011, gonna be updating her soon and this video helped alot

[@BraxtonTheMotorcycleManiac]

Yeah no problem! Let me know if you have any questions

[@jamesmarze9850]

Nice bike!!! thanks for sharing all your time and upgrades! Especially about the tip on pro circuits jetting chart with fatty pipe! much appreciated ;)

[@BraxtonTheMotorcycleManiac]

Yeah of course, any time!

[@kylemasucci1158]

Are you using a stock 03 carb? I’m having issues with mine and trying to figure out what years work with the 03’ kx250. Sick build btw

[@newellweeks2759]

What did u do for the rear shock,mine is blown very springy,,,mods or rebuild,,?? THANKS

[@joshjones8917]

Love the bike bro!

[@callsignlima84]

Awesome looking bike man, thinking of doing something like this as well

[@BraxtonTheMotorcycleManiac]

Thanks man!!

[@clappedadventures]

when you mounted the forks for the first time in the stock clamps how big of a gap was there because I'm running 2006 forks on mine and I don't wanna cut my clamps unless I know yours were the same gap as mine

[@texasdirtbikerider3335]

Bike looks amazing!

[@BraxtonTheMotorcycleManiac]

Thanks!

[@pearltongue2820]

So is that a stock triple clamp? I've got an 03 kx250 and a front wheel off my 07 kx450f supermoto. I want to put the wheel on my 250

[@chadebel2970]

Sweet bike nice job

[@travisstucki485]

I bought forks off a 2013 rmz 450. The forks slide right in but my brake rotor doesn’t line up with the caliper. The pads and rotor bind. The caliper kings up and mounts perfectly and so does the axle bolt. My question is if you had to change anything else to get then to work. Did you run different spacers or a different front wheel? Thanks Travis

[@BraxtonTheMotorcycleManiac]

My air forks that I put on mine were off of a 2015 KX450f. All of my stuff lined up, are you using rmz forks on a kawi, if so that's probably your problem.

[@travisstucki485]

@@BraxtonTheMotorcycleManiac ya, I had to switch the wheel spacers to one Kawasaki and one rmz spacer to get them to line up. Took it out to test ride and start working on some setting and tore my acl in a rut. So it’s going to sit for a while.

[@BraxtonTheMotorcycleManiac]

@@travisstucki485 gotchya, dang that's a bummer. Hope you heal up quick, getting hurt always sucks

[@travisstucki485]

I am wanting to rebuild my 03 kx 250 and the rear shock feels really bad. Have you looked into swapping it out with anything a little more current?

[@BraxtonTheMotorcycleManiac]

I've thought about it but mine feels pretty good. I was having the hardest time trying to tune the OEM forks on the front which is why I switched to the SFF air forks that I have now.

[@johnnytorres2809]

Bike looks so good man great job I’m looking to do something similar to my O3 as well would love to get some feedback maybe help my build go smoother 👌

[@BraxtonTheMotorcycleManiac]

Yeah for sure man anytime! What questions you got?

[@robertococcia9815]

Hi man i have a kx 250 2008 this is my personal opinion the original plastic are better of than restyling plastic

[@BraxtonTheMotorcycleManiac]

Yeah, I just like how the new bikes look

[@travisstart9290]

haha this bike is for sale on craigslist right now.. poor bike looks like someone hammered it, u should buy it back and bring it back to life.. in el paso texas for $2800

[@marcusgest9970]

Is it still for sale?? I'll go get it this weekend lol.

[@frankie1998fs]

What plastic kit is that bro

[@BraxtonTheMotorcycleManiac]

I got it through txrace.com

[@dustinvoigt8488]

Did you happen to sell this bike? If you did I'm like 90% sure I have it. Not sure how many other people did this exact crossover with 2015 and 2016 parts. Hit me up

[@BraxtonTheMotorcycleManiac]

Yeah I did end up selling it, you in AZ?

[@dustinvoigt8488]

@@BraxtonTheMotorcycleManiac I lived in AZ for a couple months but moved but to Cali. If you wanna see it or something just lmk man

[@kaleb_zzz]

Wheres the motovlogs..

[@dennismoore6113]

the tx plastics dont line up properly if you look properly at the side plastics that attaches to sub frame it dont line up still looks good but you should look into polisport restyle plastics for kx 125/250 line up so much better than the tx plastics and the polisport restyle plastics are a knewer look 2019/2020/2021 were tx are 2016/2017 I've got both styles and polisport put the tx to shame buddy

[@BraxtonTheMotorcycleManiac]

When I did this plastics kit TX was a lot cheaper to do and only one available at the time lol. I sold the KX not too long ago.
