[blasterak]

Hey... my dad just got a beat up 87 250X from one of his co workers for only $400.. pretty good project quad. It needs ALOT of work though. What can you guys tell me about this quad. Whats the diff. between the 250X in the 300ex? Arent they just like the old model of the 300ex? Also what are some cheep mods for it like what parts from lets say a 400ex etc... fit on here like make it wider etc..? Im new to this 250x/300ex crap im used to the Blaster cause thats what I own anyways I know youll all prolly say "press the search button" but please I want to hear from you guys straight up... heres some pics of it.. its beat lol

also if you know any good 300ex/250x based forums let me know too Thanks

it doesn't look too bad. go through the motor and check the valve adjustment, change the oil and replace the air filter. the valves can tighten up over time, then it'll start hard and you'll lose power. all chassis parts interchange with 300ex with the exception of the front hubs in 87-88 250x's. the head and cylinder are the same. the 300 bottom end is different and beefier. you can put 400ex a arms on, but they have a bit of bumpsteer. a 350x rear axle is, i think 1-2 inches wider, do a search on it though. you can run a 400ex carb with 350x airboot, and a pipe will help. with a cam, higher compression piston, and or big bore/stroker kit, these motors will run very strong, and you'll run with the bigger machines no problem.

are the bolt patterns the same though on both 250x and 300ex? both are 4/144 bolt pattern right? It sounds like these have alot of potential in them from what you said above... Thanks for the help ;) and yeah it aint to bad but its really rusty from sittin by salt water... supposedly it runs...gots dents missing bolts etc...shocks are shot.. Im also looking for a set of plastics for it so if you got a set of stock or aftermarket plastic for it pm me or post here

[300exOH]

I'm pretty sure the 87 250x had a different bolt pattern for the front wheels than all other years 250x/300ex. Rears are the same though.

[bradley300]

stock parts are really expensive for a 250x compared to a blaster, so before you buy anything stock (plastic is a biggie) check the aftermarket, because they are probably real close to the same price

He is correct 87 had an odd front pattern 4/110 that was different from all others.

They are very good machines, and run very strong with a few mods. I would start with suspension after you make sure it is going to run. I originally started with a bare frame and have almost built mine to its limits; However, I hate to say it but a 450 is callin my name after this season.:rolleyes: I put it off as long as I could.

If you have any specific question, I would be willing to give what advice I have.

Good luck and have fun.

[red rider88]

hey i got a 87 205x too.

[blasterak]

sick 250x redrider :eek2: and yeah I read up this morning that they have that weird bolt pattern 4/110 I dont plan on modding it up just get it running right and use it as like a play bike/trail bike my main ride is my Blaster.... thanks for the help guys if I need anymore help Ill just ask you guys ;)

[VT250X]

I have gotten tons of good information from this site. There are a lot of helpful people here that are more than willing to answer questions.

Here's a website I visit once in a while. It's nothing but pics of 250x's.

Later,

[blasterak]

When I go to that site it just brings me to this site with pics..good site tho thanks...
I have a question for you guys though.. Has anyone put like either a 400EX or 250R Rear shock on these? Cause I know on my Blaster im running a 250R rear shock... Or are they too long for it? If you guys know anything about this let me know.. Later

[VT250X]

The rear shock on the 250R is a one problem. The swingarm is the main reason why it's so hard. They have a pivoting linkage on the swingarm itself. Unlike the 250X which is a rigid mount. Even if you did away with the linkage, you would have to fabricate some way of mounting it to the swingarm. Probably not cost effective. If you didn't want to shell out $400 for a aftermarket shock most of the people here wuld probably say stick with the stock one or buy a newer used one on ebay. Search the 250R forums for some pics and you will see what I am talking about regarding the linkage. A 2001 rear Raptor shock will also fit and it has a rezzie. They seem to go for around $150 or so on Ebay when they are one there.

As far as the link above that's all that is there is pics. I look at it to give me ideas on products I am interested in purchasing. Most of the pics in catalogs and websites direct you to a pic of the product installed on a different machine. Mostly a 400EX from what I have seen.

Yeah we'll figure something out on it cause like I said im running an R shock on my Blaster and ill we had to do was drill out the shock mount to a 14mm diameter and get a 14mm bolt and put it on.. wonder if thats the same with this machine.. anyways I have another Q for you guys... would like a 400ex throttle work on this machine? Cause I know guys on YFZ's switch to 400ex throttles cause there supposedly much easier to push... let me know guys later

[bradley300]

theres not any problems with a 250x throttle, just keep the cable in good shape and lubed. if you get thumb pump real bad or have small hands, you can use a trx 90 lever. it bolts right into the 250x throttle housing

[red rider88]

im not sure but i thnk i got a 400 swingarm on it to but ill have to ask

[blasterak]

right now it has a POS twist throttle that does not work at all so I was just wondering that because Ill have to get a new throttle anyways cause I dont care for twist and it does not work at all so I thought mite as well get the 400ex if it works on it... ;)

[blasterak]

ok I tried searching but nothing came up and theres like 2000 pages to look at.. but do you guys know if 400ex front brake calipers work on the 250x/300ex? let me know asap theres a set on ebay ending soon. thanks

[VT250X]

Hi. I just checked bikebandit.com and they show the same part numbers for the 300EX and 400EX. According to them they are the same. I hope someone else can confirm this before the auction ends.



LM

[red rider88]

i got them on mine but i also have 400ex front end

[blasterak]

Yeah I missed the auction but oh well..
but anyways here are some pics of it how it is right now but now the engine is out of the frame its a bare frame now:

Reminds me of when I got mine. I got it at the end of the fall. Winter was on it's way so I stripped it down to every little nut and bolt (minus motor). I organized everything, replaced a few worn items, bought some new plastic and then I did nothing to it for the whole winter lol. Spring came and my buddy asked if I wanted to ride the coming weekend and it was a scramble to get it back together. I never got to paint the frame, a-arms and swingarm. Not having heat in the garage didn't help matters any. I have a furnace in there now and winter this year is going to be spent painting.

What's the matter with your front brakes (or are there any)? My fronts were ok, but the rear was seized and all crudded up. I purchased a rebuild kit from hyperparts for like $20 and rebuilt mine. It hasn't leaked or had a problem since I re-built it. I had never worked on an ATV before that and it was incredibly easy.

Have fun,

LM

Well one of the front calipers are seized like your rear was too...the rear one is fine but the front ones are not.. my dads going to take them apart to see if its fixable or see whats wrong with it. But more than likely will just get a set of them off of ebay or here. ;) BTW Ill go look into those rebuild kits. Thanks for the info later

[bryan.young1]

i think you said something about finding new plastic, but the one thats one there now didn't look that bad. you might just want to go to town on your own. it would save you some cash.

[bryan.young1]

if your intrested i have parts that came with my bike that im not going to use.

White bros e/series exaust
tool kit
stock front bumper
stock tail light
spare set of stock front tires 50% life
stock rear rims and tires 70% life

let me know

[TCracin440ex]

i had a 92 250x....i rode the livin chit out of that thing...i finally parted her out cuz i just couldnt get it sold


first thing i would do is change those stock hubs and get some newer 300ex hubs so you can run stock 400ex wheels and such because the 87's bolt pattern sucks....another suggestion is to relocate the rear master cylinder too because if not the exhaust will melt it....the brake calipers off a 400ex will work...i wouldnt use a 400ex a-arm or 400ex shocks...alot of bumpesteer....and the stock 250x bearing carriers suck..get an aftermarket bearing carrier because my 250x chewed up bearings with the stock carrier

Aftermarket is definatly cheaper than 250x/300ex stock plastics.

THe problem these guy's are trying to point out.. it that new plastics are going to cost you nearly as much as you paid for the ATV.

You might be able to find some used ones.. that people swapped out fullbores or something for though.

I see the hole int he rear plastic on the right side near the kickstart.

Your front plastics look great. Take a look at the UFO rear or Maier rear. Keep the fronts. Just use some tire foam to shine it up again. ;)
