[atvfrk10]

[atvfrk10]

[400Rider022]

[deathman53]

you gonna do suspension also? also with the shaft drive you are pretty limited as fast as it will go, I don't see a point to doing anything to it, just a waste of money and btw a big bore kit is just a 80 over bore kit, it brings it to a true 250, not a 230(like stock). Hate to hell you but xr200 motors have more potential for hop up than a 250ex motor.

[atvfrk10]

Yes i all ready have a suspention on mx 250ex. Also maybe i dont want a 400 (all ready have a full race z400). Plus maybe im doing it cause i just want more power anyways big bores dont make speed they make power

[Flynbryan19]

Your going to have trouble finding company's that offer BB kits for the 250ex. Theres just no interest.

[atvfrk10]

in the first sentace i stated the brand i want to get so i know where to find it, any way were getting off the subjuct all i want to know is how the relibilit is on a powroll 250ex big bore kit. I dont want any I THINK, ITS A WAST OF MONEY, or SAVE FOR A BIGGER QUAD. I just wanna know how the relibilty of that kit is

http://ohiomafiariders.com/v-web/bulletin/bb/images/smiles/wtf2.gif What in gods name did you just say


I'd personally take that money for the bore kit and spend it on some engrish lessons :o

[atvfrk10]

Well saying "engrish" doesnt help

no one knows because no one is dumb enough to do it..you be the first Mr. Know-it-all.

[atvfrk10]

That is a dumb statement, if im "Mr know it all" Why am I asking about the kit.

well, you sure ain't speaking english :o :huh

[redrider440]

I cant believe anybody buys suspension for a 250EX, especially if they own the all-mighty z400, let alone a big bore kit for it.

[atvfrk10]

im doing it because i cant run a z400 in the 0-350 class

[quadrcr161]

then sell the 250ex, and buy a 300ex, more potential, and better quad.

edit: anytime you mod something the realibility goes down. you ride it harder, running higher compression, and more pressure on the bottom end.

[atvfrk10]

maybe i dont wanna buy a new quad and only use it for 1 year. plus the 250ex engine needs a refreshing. Now will someone just answer the question

[Bush0102]

as for the reliability of the big bore 250.....


yes, a 300ex is pretty reliable.


why are you wasting your money?

first you say you want power, not speed, but you are going to be racing....what the hell? you've got some wires crossed.

second, if you have a z400, why the hell do you want to race in the 0-350 class anyway? You're going to get eaten alive by blasters, 300EXs, and Raptor 350s.

Dont waste your money trying to turn a shaft driven kids toy into a racer.

and this has been a funny post, thanks for the laughs guys...

[atvfrk10]

If youve raced mx you know you will hardly ever go top speed its slowing down the speed up slow down speed up not top speed. and maybe I wanna ride with friends and just have fun. Also its not the bike its the rider and just because it is a 250ex dosent mean it cant jump. it can do anything a 300ex or blaster can do.

Is that right? Can you change gear ratios? What about powershifting? Start in gear? How about finding aftermarket parts EASILY? :cuss:

[UglyMotha™]

retarded kids :rolleyes:


I have to admit you have made me laugh the entire post

[yellowWB400ex]

Me too. Me too.:D

Just remember

Fighting over the internet is like winning the special olympics, it doesnt matter your still retarted.;)

[atvfrk10]

yes all (but start in gear although z250 can) it wouldnt be fun to change gear ratios but some people have done it. but i dont care if you hate them, think they suck, or what. cause i have one and i dont care what your opinion is

[Alpredator]

Whats wrog with fixing up a 250ex? You guys fix up 400exs and no one tells you hey thats an underpowered outdated turd, go buy a 450. Why not just tell him you dont know.

[atvfrk10]

thank you i have to agree with Alpredator

its not a wise descision because the 250ex is very limited in performance unlike the other sport quads like the 400ex, even a 300ex. the lack of suspension, power and the shaft drive kills any "sport" potential the quad has. building a 250ex to even compete to a 300ex will cost more then then its worth, when you can find a good 300ex for under $2000. honda released the 250ex as a beginer sport quad, for young people to grow into a larger quad.

[rodenberg35]

I say do what you want with your ex. Go with big bore just to be different. My wife has an ex and I ride it all the time. mostly so I dont hurt the 450 but sometimes just for the hell of it. It is probably more my speed anyway

[Alpredator]

I also say go for it, that poweroll 250ex may be a beast and that would be gravey if you did indeed beat some 300s and blasters in the process.

[atvfrk10]

Yea i wanna get it but need money and im tryin 2 ask people how reliable it is, and do you have to use racing fuel if you get the big bore kit?

bump..someone help this kid... please don't let this thread die...its been a good laugh

Well you must have taken Ugly's advice because there are now fewer spelling errors in your post!;) Nice job man.

Keep up the good work:cool:
















:p

[redexrider4290]

y is everyone cutin on the 250ex and saying the 300 is some great thing i have a 250 and my freind has a 300 and anything he can do i can do somethings even better (such as wheelies) and even when we are going acroos a feild or something at top speed im still keeping up with him
so i dont see y you cant bore a 250 to me its pretty fun thats y a just bought a hmf full system for it

I would say if its done right, you should be ok. As far as race fuel, you will have to run it if you compression is high enough.

[300EX777]

you guys are killing me with this thread!!!!

i will actually chime and tell you that the powroll kit is very reliable. powroll has been in business for 40 years. there kits are researched and tested extensively before they offer them on the market. i just ordered a kit for 300ex.

now as one of the other posts stated: once you put a big bore kit in one tends to ride harder than normal and anything can happen to a built motor.

good luck and have fun, btw i have been beaten by a 250x before!!

the kid says he can do anything a blaster can do, i dont beleive he can do anything close to these quads, and theres pics of blasters doin 95 ft tables. www.projectblaster.com , and shame on whoever told him what he wanted to know, this was really a funny thread haha.

[brokeitin3]

i have a powroll big bore kit in a 250ex engine, did it back in 2001. its been rode hard ever since, and no you dont have to run race gas with this setup. i also got works shocks, durablue axle, and extended arms on a 250ex. i love playin on it


i also still have the r's

if a 400ex is outdated and underpowered, where does it leave the 250ex?

no crap............... you still alive guy :eek:

[PowerJunkie]

this is not me talking but ive read it alot that 250ex arent good to bore they have problems but i dont now just what ive read.

[honda400ex2003]

I used to have a 250ex. That was a fun lttle bomber. I kept up with a blaster with a pro circuit slipon on it, plus I could jump it jsut a good as teh blaster. I have had a 400ex for 2 years and still like riding that thing. It takes you back to no power, then you go get on the 400ex and romp on it with a tone of power again. It is sweet. I have seen 250ex go where even grizzlies and rincons and stuff can go. These 4x4's even had mud tires on a few. I think it would bre cool to bore a 250 just to see what it is like. Just my two cents worth though. Steve

[psuperman112]

i'd be interested in the bore kit. i dunno why everyone is on ur case for. I have a yfz but also have a 250ex as a second quad (aka tag-along ride). the 250ex is a great quad for first time riders, and while my yfz was in the shop i took it out to a mx track and it held up WAY better than i expected. if you do get the kit let me know about it.

[trict_out]

To each his own...it is YOUR quad and YOUR money. Do what you want and try not to let people get you down with their comments. I've owned both a 250ex and a 300ex and i think a 250ex with a powroll would have no problem keepin up with a 300ex not to mention be fun to play on.

[crazycray200]

for more power out the corner starts etc i would change the sprockets thats what i do for racing and it works

people got down on the back and up on the front but that is wrong

you are suposto go 1 on the front is 3 on the back
in running a 13 or 14 with a 41 but the bigger the back one is the faster you go!!

good luck

[atvfrk10]

yea that would work, if only a 250ex had sprockets

[400exrider707]

What amazes me is most of the people telling you not to do this and saying that this is a funny thread, are the same people who will post a complaint about "immature kids" posting useless crap with no information.:rolleyes:

If you are doing strictly MX then perhaps you might want to look at the 300ex just for ease of gearing changes and availability of parts, but if this is what you have and what you want to do then more power to you man. Just remember though the engine is only as reliable as you build it. If you dont want to run race gas then you should contact powroll and tell them that. Im sure they would be able to hook you up with a nice setup where you can run pump gas. Your right it is mostly rider as well. Last year my buddy swept the novice class full of 450s and 400s on a nearly stock 300ex. There were a couple of races when he caught up to and even PASSED amateurs that had started 15 seconds before us on a staggered start.
