Make That "New" Bike Feel Like Your Own! Radical Upgrades for the 1999 KX250

[@rockman49er]

Wow the nuts from your kit fit the bar mounts is awesome i didn't know i actually have the nickel works hardware kit now i know what im doing after my coffee 😀 thanks

[@GregHitchko]

Haha right on dude! Always have to start the day off right with the coffee as well. Rad you have the nickel works kit as well. It's a nice set

[@jordanwright9780]

I’m old enough to remember these days and miss them! I rode purple too, KXs were/still my fav of this era. Thanks for the memories. Best video yet!

[@GregHitchko]

That’s awesome Jordan! I appreciate the feedback. Really takes me back too. That’s what it’s about 🙌🏼. More to come that’s for sure ;)

[@brettlaage9687]

That's exactly how I am able to work on my bike! Those baby mo itors are awesome!

[@GregHitchko]

Dude they really are Brett! It's nice to be able to get out and get some garage time while they nap. It's usually always a scramble for me to get clean when he wakes up because I push it too far haha

Dem bars 💜

[@GregHitchko]

Oh yes. Yes, YEs, YES!

[@empiresrikesfat]

Great video, purple bars looking sweet, i have my forks set low about 2-3 millimetres above clamp..

[@GregHitchko]

Right on! Thank you for the advice on the fork height. That sounds like a good place to start.

[@misfit1-3]

just got a 99 kx250 absolute beast

[@GregHitchko]

Heck yeah! Dude they seriously are

[@Bixbysayshi]

I have a 98 Kx250, & by FAR the most balanced & settled the bike has ever felt is with an 80/100-21 front, 120/80-19 rear (either MX33's or EMEX T-35's), forks 1.5mm lower than the stock position mark/ring, somewhere around 104-105 sag on stock springs front & rear (make sure your nitrogen bladder is 142 PSI & holding pressure), with compression somewhere around 8-12 clicks & rebound around 12-15 clicks on the forks, & compression around 12-14 & rebound around 9-12 clicks on the shock. I try to bleed the forks as regularly as I can, and run 12-14 PSI depending on how soft the track is. I live in New Mexico, so it's incredibly slick hard pack (think unfinished concrete) with pebbles, rocks, square edges, and super inconsistent traction due to all the sand and moon dust over the hard base, and then we have to deal with SUPER deep sandy/moon dust corners. but so far this setup has been money

[@GregHitchko]

This is some fire information my man! I will definitely put this to use. I know what you mean about riding in those moon dust type conditions after spending the last four years in Utah! I know I’ll be a little heavy for the stock settings but plan on getting the correct springs and work done to it soon after I first ride it. Much appreciated! 💨💨

[@Bixbysayshi]

@@GregHitchko of course man! I weigh around 185 without gear too, I forgot to mention!

[@phatheadracingmx]

Definitely get the JIS drivers and awesome trick with the WD. Easier than the air compressor

[@GregHitchko]

I need to grab an air compressor again after the move or else I would have tried that first lol. The WD does work pretty good too!

[@08dangler]

Awsome video pal 😎👊

[@GregHitchko]

Thank you my good sir!

[@evo5349]

Had a few of these Kx250's and the only problem was snapping the damping rods in deep sand and at Hawkstone Park Paul Coppers mechanic swapped the rod out in between races swapped it out. This was in the UK.

[@GregHitchko]

Oh damn! Snapping the damping rods?! That sounds intense. Hopefully I don't have that issue. If I do, it seems I could find a set of forks on ebay or something. Or a part out. Why just in deep sand did they snap?

[@evo5349]

@@GregHitchko You have too be going some to do this and Hawkstone Park is very rough and was after a European championship the day before.

[@JohnDLeo-rg8tc]

Greg, it's great watching you work on the exact same bike as im lucky enough to own. I hope to see you get tons more subs, you certainly deserve it my friend. Your friend from Canada

[@GregHitchko]

You gave me chills because of the kind words, thank you John! Looking forward to getting more videos out on the 99 as well. It is a really fun bike. I've played more youth hockey in Canada than I can dream but hopefully someday get up there and ride some moto. Where are you located?

[@JohnDLeo-rg8tc]

@@GregHitchko oh man the sun rose and set with hockey for me. It warms my heart that you played youth hockey here, probably somewhere in Alberta i'd guess eh? I live in Ontario, grew up in Toronto but now have a bit of property and live more in the northern part of Ont.

[@Nahtanoj65]

Man this thing is so clean, so wild looking at the same bike I have but the bolts haven't been removed 1000x lol. On my forks (99) I believe I followed the Clymer manual and left 5mm or so and it seems to handle well. I have racetech gold valves and my bike was set up for a 170lb rider. Love the purple bars, you're making me want to swap my black pro tapers 🤣

[@GregHitchko]

Hahah dude these bolts will for sure be removed 1000x by me as well now, that is for sure. Thanks for the heads up on the fork height, that sounds like a solid starting point and then test from there. How do you like the racetech gold valve set up? I'm thinking about doing the same thing I did with my shootout bikes for this set for forks and shock. It's going to be way too soft for my weight and ability in stock form. I also support the purple bar move haha. Get on Renthal'e site and see where you can grab a set before they are really all gone. I'm sure ebay could have some too!

[@Nahtanoj65]

@@GregHitchko I'm probably a bad reference since my bikes suspension was clapped when I got it, so racetech is all I know. Can't beat setting things up for your weight and riding style, I'd definitely ditch the stock stuff. I have a local guy, shock zone suspension services, that set me up. He does remote work for people as well!

[@GregHitchko]

@@Nahtanoj65 so true! Nothing beats getting it set up for your weight and ability in terms of performance and safety.

[@travisferrell592]

Schedule the ride video for a track I can make it out to!

[@GregHitchko]

That is a true story! A little this gen VS the last gen KX250 test perhaps?

[@aussiedigger1441]

Procircuit build would be so dope! I have a Procircuit stator cover, pegs and pipe and silencer on my 01. I would absolutely love to get a high flow water pump from boysen and I think Procircuit did 1 also. I can't find 1 anywhere (definitely not in Australia)? Loving your channel!

[@GregHitchko]

Dude hells yeah! These pro Circuit parts are getting harder to find for sure. Nothing beats the look of these generation PC bikes man 🙌🏼. Thank you for the kind words. The serious PC build will be going down at the beginning of the new year I’d say

[@mikeguliz]

looks like nice clean bike

[@GregHitchko]

Thank you sir!

[@hunterhill1013]

Bro! Where did you find those purple renthals! I need some for my Kdx I cant ever seem to find any

[@GregHitchko]

Head over to renthal's website and they have a dealer finder where you can possible find them. I'm sure there are a few straggling pairs out there!

[@deanbigginton2251]

You will want the rubber ones back in on the handle bar's 😏

[@GregHitchko]

I was thinking about that actually! May have to do a test too feel the rigidity difference. The stock forks will for sure feel soft for my weight and ability so that's why I went with the solid mounts first. Keep you posted when I test them!

[@julienvidegain5480]

Awsome video! You just earned yourself a new subscriber.

[@GregHitchko]

Thank you Julien! Very much appreciated. Pumped to have you aboard the train haha

[@Finessing_Sam]

May I ask what the tool is called that you used to shine the bolts etc. it had the wire wheel and soft fine wheel? Also what bolt kit do you recommend?

[@christophersmithsonian3350]

What type of 2stroke oil The Best ? I've told you many times Blenzal Racing Castor/VP MRX02 🏁🏁🏁🇺🇸🧐 yes the MRX02 is pricey but the throttle response is worth it

[@GregHitchko]

I really need to check out MRX02! The cleaner the fuel the better for the engine that’s for sure. I need to check out the budget and see where I can get it lol!

[@331moto]

Depends on how and what type of riding you do. I prefer klotz R-50. I woods ride and do some MX. Castor oils are great, but if you aren't wide open and running the bike hard they tend to gum up. Klotz R50 burns clean at lower engine temps and rpms and smells frigging awesome.

[@pc2150]

Dunlop makes repop 990s those tires were the best.

[@GregHitchko]

I need to look into that!

[@michaelanderson2689]

Should of fitted an alloy throttle tube, then plastic one break or crack and possibly cause the throttle to stick open, alloys ones are stronger!

[@GregHitchko]

Thats a great suggestion Michael, thank you! I need to look into those without a doubt.

[@ZLRBUILDS]

Get some vessel screwdrivers! They are JIS.

[@GregHitchko]

Haha dude I need to get some so bad and stop being cheap 🤣.

[@Noah_MX251]

I have the same bars same color for my 110l Or I ordered them

[@GregHitchko]

Heck yeah! Love the purp 💨

[@mikeguliz]

I would try that unknown tire you never know at least burn that tire out.

[@GregHitchko]

True story! Seems like more of a hard packed tire, wasn’t bad but wasn’t great. Maybe it’s worthy of a burnout haha

[@leonibs5034]

Gotta be the weirdest way I’ve ever seen to remove an old grip. A razor blade down the middle (cutting it in half. and they just peal off.

[@GregHitchko]

Proud to wear the crown of “weirdest way to take off grips.” We are a little whacky over here 🤪.

[@GrandpaDon69]

A radical upgrade would be a 4 stroke 😂
