250EX Powroll kit just installed

I just installed the powroll kit for my 250EX it made it from a 229cc to a 249cc I got alot more torque a big increase through the whole band plus I purchase a slip -on megaphone and muffler it increased power by 10% over stock . The top speed is 67 mph on radar and 68mph on speedometer. I beat the my on blaster in a drag race on the weekend barely but it still beat it.

[Nausty]

how much does the powroll kit cost total?

It cost 329.92 for the Bore kit

[brokeitin3]

the new cam? i hear you must split the cases to do that.

[kxrider]

is there a website for powroll

[user101]

there is no way ur 250 is goin 67mph. no posible way u might me pushin 60 if u somehow changed the gearing in the engine. or u have some really big tires on there.

I wouldnt be saying it if it wasnt true

[kxrider]

my 250ex tops at 58 with pipe, filter, jets,22 in tires,stock

this is the powroll website www.powroll.com

[kxrider]

thanks, you installed it your self

some motorcycle shop did it for me

[brokeitin3]

Thats great if it does, but mine only goes 51 top speed. Thats with the 20" holeshots and stock engine. The guys at powroll say that the piston kit will not increase top speed, just get you to the top speed a whole lot quicker. But anyways I plan on documenting the whole installation step by step. I am not expecting a huge top speed though, just a lot more low end pull for wheelies. But anyway it will be at least a couple of weeks to complete installation. I'll give you all the details then.

[kxrider]

do you have to run race gas now or what, and if you have 20in tires on your 250 it is just like gearing it down

[brokeitin3]

is not possible on a 250ex. I'm just trying to figure out how you measured your top speed and such. Are you running the factory tires and what size main jet did the shop install? Im just trying to figure out if mine will run the same or not.

[kxrider]

i don't know how he measures his top speed but i just run next to a truck, on the road

The shop told me they went up three sizes on the jets and my tires are maxxis Razr front and rear

[brokeitin3]

20" or 22" tall?

22'' in front and 20" in the rear

[brokeitin3]

MINE SHOULD DO ABOUT THE SAMETHING THEN

[HoNdAdude48]

LMAO- thats hellarious 68mph!:p man what were u smokin dude! lmao! thats like saying ur 250ex could beat like a 400ex! LMAO!

[brokeitin3]

Did anyone recall asking for this guys opinion?

[HoNdAdude48]

brokeitin3- do i care what u think? uhhhhh ummmmm hmmmmm...............NO!

[Striker49]

EZ fellas...no need to bicker over nothin. lol.


But still....67 :huh That is insane. Mine runs around 51 stock but im really surprised that those mods make it run that much faster, especially with 20" tires. That means if you put the stockers back on you would run like 70-72. :huh It doesnt really add up but if you say so I take your word for it. Pretty neat, now you gotta get some suspension to handle it. Those stockers are shibby.

[muff]

wow, i'm suprised that they even did 51, my recon only did 43 and that was slightly down hill, and i hit 68.6 on my 440 almost maxxed out, thats measured with a trail tech speedometer and that was calibrated right, so i highly dought you hit 68, but hey, if you say it goes 68 then you can bring it over and well see how it runs side by side to my 440

[honda250xrider]

not to be a prick or anything but i dont think it will run that fast because if you are going 68 you could whip me on a drag but stock you only run 50 to 51 according to some people i dont know the true speed but you do not gain hardly anything on top end doing the bore you only get there faster and you can not change the gearing in the 250ex so there for you would have to of had the gears changed inside the engine

[HoNdAdude48]

hey watch out now stricker! brokeitin may flame u for no reason & send u a stupid pm!;) or @ least he did that to me!

[kxrider]

well speaking of suspension i am fixing to get some practicaly brand new banshee shocks, with only 5 hours on them, and i don't know if all the 250ex people know but front banshee shocks fit in the rear of 250ex, anyone wanna buy one off me, 60$

do they fit exactly or do you have to do some mods to have it fit

[ryanh250ex]

68 mph is bs. i own a 250 myself (piped with a t-4 complete system and jetted) and i highly doubt a bore kit with a pipe and jets would bring the top speed up 15-20 mph. i could see MAYBE a 5mph gain on the top end at most, but not like 20. that's just absurd

[01TRX300EX]

Well maybe it was loaded in the back of a truck and he was on it while someone was driving the truck. Or maybe he took off the rev limiter and thats how fast he got just before the motor went BOOM!!! :D

[super_man37366]

THE REV LIMITER WILL SHUT YOU DOWN!!!!!!!!!!!!! 50-54 POSSIBLE BUT 68 MAN THAT A DANG STOCK 400EX RUNS THAT SO THINK...AND SOMETIHNG ELSE WHEN YOU STARTED THIS THREAD U BASICLY REPEATED WHAT POWROLL STATED..... BUIT BELIEVE WHAT U WANT.. ONE LAST THING POWROLL E-MAILED ME AND SAID IT WOULD NOT INCREAse TOP speed...AT ALL.... LATER

[kxrider]

no shocks line right up

[Nausty]

I don't beleive 68 unless you got some super tall tires. Even if your quad COULD pull it it won't because it can't pull high enough rpm's and you didn't change the gear because well you can't other than tire size.

[DMC mx400ex]

not to be a "hater" but i own a 250ex and i dont see it reaching 68 even with a bore kit and pipe and all that sh*t

hey can you really get the gearing changed in side the engine. if so how?

[kxrider]

yeah you have to break down the whold motor, and then put high or lower gears in

[330exracer122]

hahaha my 330 kit doesn't go 70 mph lmao a 249 hhahaaha

Haha, thx man....and Hondadude...me and brokeitin"3" are cool. lol. He did send me a PM but it was info bout his bike and stuff. :cool:


And muff...the reason the Recon wouldnt go as fast is b/c of several reasons
-Any model year under 2002 has approx 10% less power than the ex. They took the Recon motor out, souped it up, put it in the ex, and took the ex motor and put it in the 2002 Recons.
-A Recon is bout 50 lbs heavier (give or take some) than the ex
-Recon's are geared lower b/c they are utilities and are used for pulling loads where the low end is needed most.

That maybe helped ya out some muff. :cool:

[mudderchic]

Yeah, I think the weight of the Recon makes the biggest difference on speed. I don't know for sure about the top speed of the 250ex, but does it really matter? I do know that you can only go as fast as the engine will spin, so with all the basic mods (even the Powroll kit), you will have the same top speed, just a far greater acceleration speed. But I still love my 250ex because it whips my 90 lbs. around enough to scare me anyways :)

yep the cam is between teh front and middle casing. its a pain.

[03y85]

my 250ex uns 58mph my brother had a raptor with a trail tech speedometer and clocked me his raptor only did 72mph

[CG's]

Powroll is correct. A 250Ex will not gain 10-15 mph with motor mods(100%garantee). Now if the rev limit was raised, or larger tires, or gear changes were made then it would be a different story.

ya but if he got a new came it would give him a lil more not 13mph , it proly feels faster cuase your exclerating so much faster??

[DirtDiggler]

we took the 20" stock rear tires off my 400ex and put them on my buddy Steve's 250ex and he got 47mph going down hill hitting the rev limiter all the way. The 20" tires are going to reduce top speed and you would need more rev limiter than the engine could handle to get that kind of speed.

Top speed runs are more accurate with a speedometer or a gps. Anyone I've ever watched run with a car or truck always gets numbers way on the high side.

Ex.
My buddy Nick said he ran alongside Jody's truck and got a top speed of 71mph on his stock Warrior.

My 400ex does 68 on a gps and I can beat him in a drag from the beginning to the end and he's a slightly better rider than me. I don't think his warrior does much over 60 and based on drag results it seems a lot closer to my estimate than his truck speedo test.

Realisticly your mods should lower your top speed but get you to your top speed much much quicker. Unless you have some way to change engine gearing and rev limit.

[bradley300]

this is the dumbest mod i have ever heard. first of all, any front shock put on the rear? you'll blow it out in no time. second, what is the first thing all the mags complain about on banshees (well, second. airbox is usually first) HARSH SUSPENSION, FRONTS MOST NOTABLY) i garuntee you will see a loss in suspension performance by doing this mod, dont waste your money. save it and buy a better shck, like a works or elka, not a worse designed stocker.

do you have any idea wat your talking about?? have you ever ridin a stock 250ex?? have you ever ridin a 250ex with a banshee shock?? , if you havnet then i dont really think you have any room to say anything, i got a banshee shock on my 250ex, and sure it bottoms out but not as much as stock, and it rides trails alot smoother, it soaks up roots and holes alot better, i think besides my pipe that is the best mod i have gotten, i know it doesnt make sense that it woudl be better, but it does, and i have had my banshee shock on for over 1 year and its as good as new, no sag or nothin, i wouldnt reconmend this shock for someone who is seriously tryin to race or jump really big, but for me it suits me perfect:D

[bradley300]

i have never ridden a 250ex but, i do know a thing or two about suspension i would not think any front shock on the rear of any quad (with the exception of the early gas gas) could possibly beneift a ride. you must wiegh 90 pounds if that shock isnt blown yet.

the sheer fact that the banshee shock is a front and designed for front geometry says this is not a good mod. maybe for a trail rider its ok, but for anyone particular about thier suspension settings would probably say otherwise.

well if your ever in my part of town stop by and you can ride my quad with both shocks on and see it rides alot better with the shee shock

[White_Knuckles]

well if your ever in my part of town stop by ...


KX there is a question posed as how much you weigh that is valuable. A 150+ rider weight would seem to spank a front shock when used as single rear. I have seen many riders say it's works well but never state their weight.

Enjoy and mod that works for you :p

[White_Knuckles]

Uh. that would be... Enjoy any mod that works for you :p

[bradley300]

how much do you wiegh? (not being a jackass, just curious as to how much wieght the banshee shock is good for)

[kxrider]

i just weighed 2 min ago 147lbs, and also for jumping if you know how to jump you can go huge and not bottom out, i can jump 15ft gap on my bone stock xr50 and not bottom out the front or back, and the banshee shock did lower my rear end almost 2 inches just cuase its shorter, but it but the quad doesnt have any slack in the suspension when im not on it like i said it is softer than stock so it rides alot better, and its lower so it corners a lil beter:D , and i come to a conclusion, i dont really care if physics or you or anyone else say it doesnt work, i know from experience it does, you can ask jonathan ( the yella yetti) he rides my quad sometimes and he says its awsome

[Fast250EX]

I would like to hear more info on this. This sounds like a perfect mod (the 249 kit) for my local drags, a 200 foot strip. I don't care about speed really. Maybe a couple miles per hour faster wouldn't hurt but I want monstrous bottom end.

And I think I want a Banshee shock too. The biggest jump I would do on average is 6 feet. The back shock is very harsh IMO and the fronts bottom out way too easy. If you can land it right you won't bottom it out. I had a 7 foot flat landing and nothing bottomed. Of course I weigh 110 pounds but still. I just want some shocks where I can afford to be a little sloppy and not pay the consequences of an earth rattling bottoming out.

my 330ex goes 55 with stock gearing!!!

will you trade me?

[RideRed250ex]

KXRIDER...Is this lowering kit that you talk about in your info thing just how the banshee shock lowers it or do you really have a lowering kit for it?
