help! need more power/speed...how?

HELP!! i got a honda 250ex - its been Jetted, its has a TWIN AIR - airfilter in it..it has a white bros. e-series scilencer...what can i still add for more power??

[OCCRA288]

I think someone makes a hi-comp piston kit for it.

anything else?

[flaneledholes]

holes in the airbox (uni makes little filters that go in the 1inch holes). Bigger smaller tires for gearing, I dont know if there is a cam and carb for the 250 but if so get that and bore-out when you get the high compression piston.

flaneledholes, i dont get what you mean by holes in the airfilter, could you explain that to me?

Sell it or trade it for a 300ex. Also he means drill 6 1 inch holes into the top of your airbox lid. Personally i dont think you should modify a 250ex that much. The power just isnt there. You would be better off getting a 300ex. Stock it has way more power than a 250ex. Then add a pipe, filter, jets and you'll have plenty of power.

400 ex racer, you said you dont think i should modify a 250ex that much, what could go wrong if i do, or why dont you think i should

I dont want to sound like im against a 250ex. But that was made for leisure riding and a little sport riding. It would take a lot if money to make it powerful. Its not a power hungry machine. Its just not made to be powerful. You would be better off selling it and buying a used 300ex for the same price. You'll see a world off difference of power between these two machines with only 50cc difference. Trust me. I used to have a 300ex. Irode a modded 250ex(pipe, filter, jetted) and my 300ex(poweroll header, and holes in my airbox) and my 300ex simply crushed it in every category especially power.

400exrider, i know that would be great if i could do that but right now i dont see that happenin even though i want it to, so for now, im stuck with this 250ex...so im trying to make it the best it can be...

Well then are you looking for more topend or more low end.

im looking for anything lol, that things slow all around

Ok heres a few.

Bigger tires---More top end
Smaller tires---More acceleration

Bigger front, smaller back sprockets---More top end
Smaller front, bigger back sprockets---More acceleration

Hi compression piston

Try to get the White brothers header or poweroll header

sprocket? its shaft drivin lol

Oh yeah i forgot. Man i feel like a dumb@ss. Those mods will wake it up alittle. Try makin it look good to. Nerf, bumper, Bars and cut fenders

sorry about all the questions, im kinda new at all this, what do you mean cut the plastics, i know its kindof self explain...but like how

Make it look like this.

wow
how do you get them so even

Well imeasured them so they were about even and marked where i wanted them and cut the rest off with a jigsaw. Then melted the side with a torch to have it feel smooth.

cool, so you think i should get a Hi compression piston ...whats a
header or poweroll header?

The header is the pipe that is connected to the engine and connects with the silencer. The two best are white Bros and poweroll. How old are you?

17, when i got my scilencer (e-series) they said they only make the scilencer, not the full pipe...

Oh ok. Well they probably will come out with it. But a hi compression piston will do the trick. By the way im 17 too.

do you have a guess on how much a hi compresion piston is? and is it alot of labor, b.c i cant do it...so im going to have to pay someone to

I know Pro Circuit makes a full system. Maybe sell the White Bros and buy the Pro Circuit full system. Just a thought.

Well theres a kit you get. It has everything you need. It will cost no more than $150 but i dont how much money it will take to have someone put it in. Im getting a 440 national motor in as we speak for about $2500.

[Rastus]

Do you want more acceleration, or more speed?

A high comp. piston shouldnt be too hard to install. I dont know about a person that never has done it before,but its easy for me.
A high comp. piston probably wouldnt cost much.

im thinking on waiting to see if the white bros comes out with one...i reallly like the e-seiers it gave it more then i had expected,
but i noticed that on like a 300ex, and the 400ex, when you put the full headers on it, that the pipe that connects the front of the engine to the scilencer, it's a lot bigger then the stock pipe, but how come on 250ex, they look the same size

[Rastus]

300EX/ 250X headers are just small for some reason.Thats why if you have a 300EX/ 250X , id would be best to get a full system.

I have no clue on that. They should be coming out with one soon.

250 er, i have a 250ex, the semi-auto 2001, not a 250x

400exracer, whats this kit called

[Rastus]

I know. Theres a big diffrence between a 250X and a 250EX.
a 250X and a 300EX are basically the same thing.Except a 300EX has electric start, and its bored alittle more.

im not for sure what its called. Go to www.Wiseco.com Maybe that will help

does this kit come with that high comp. piston

Yep

allright, i gtg, thanks alot, you were a huge help..thanks
