250vs300

[SeanOO13]

would a piped rejeded carb and bored 250ex win agenst a 300ex with a pipe?going on asmall in clin with no bumps.(drag)

[Honda TRX250ex]

bored to what? and it would most likey hit the rev limiter. depends on the riders skills and what kind of racing too.

[ZeroLogic]

It would be close but the 300ex would take it I belive.

[BlasterEaten250]

3 hunny will win probably because the 250 will just hit the rev limiter

[Honda TRX250ex]

300ex would def. win because the 250ex will his the rev limniter. Now if the the 250ex had a higher rev they would be about even.

[300ex13]

tree hundy all day

[edak]

My 250ex jus had a pipe n airfilter..raced a 300 we were dead even till the rev...but i beleive if u bored it it would take the 300 till he caught ya

[lt250rm]

ive never hit the revlimiter on my lt230s it just stops pulling. My quadracer just revs untill you blow the motor up. But the 300ex would deffenatly win unless you up the rev limiter.

exhaust on a 4 stroke doesn't make the significant performance gains as exhaust does on a 2 stroke

what do you mean by that?i dropt a dg pipe on my 250x and it dynoed out at a gain at 9 hp.my buddy put a toomy racing pipe on his blaster and only gained 6?his was jettid to i jetted my x and came out to a totall of 11hp.not to sound rude but i think you'r wrong.but a think u could bet a 300ex if u only changed the rev limiter.

[BlasterEaten250]

i dont think you gained 11 horsepower with just putting on a dg pipe:ermm:

While the 2-strokes also benefit greatly... especially like the Banshee, most 4-strokes, especially the newer and faster ( So tosay- high performance) models like the YFZ and 450r come very resticted. So... while the 4-strokes do not always give you the greatest gains with a pipe, they do help alot! Some two strokes come with pretty darn good systems stock anyway.

Basically, while you are right... that statement does not always hold true for various BIKES... which is what makes the difference, right?

BTW, ONLY exhaust will not give an 11HP gain. That is very wrong LOL.

i got a dg kit.i was wrong my dealer said it was just a pipe.but it really was a pipe,header,jet kit and a air filter.thats wat gave me the most power.with a slipe one i got 6.all he needs to do is get a filter and a rev limiter.

[BlasterEaten250]

I have a filter, and cant even beat a blaster, rev limiters wont do much when they pull away from you when you are in 3rd gear.

Sorry, but that is still overrated power gains. I doubt you got 6 with the entire set-up... but maybe. 11HP is alot, especially on a bike not making much in the first place...........

you have to understand the fundementals of the 2 stroke cycle. Exhaust on a 4 stroke basicly all it does is evacuate the cylender on the exhaust stroke and directs it away from the rider and quiets it down. Where a 2 stroke pipe acts as a power adder. Sound waves bounce back from inside the pipe back into the cylender then back out drawing more exhaust gasses out of the cylender. Hence the bulge ina 2 stroke pipe thats what its for. This is what the power band actually is on a 2 stroke its when the motor is with in the rpm range that the sound waves bounce back into the cylender in sync when the exhaust port is open(piston is below the port). When your talking about 15 plus year old 2 strokes the stock pipes are tuned to just enhance the performance a little bit whice is whey almost every 250 tecate,lt250r, trx250r, and older banshees have aftermarket pipes on them. A DG pipe isn't considered aftermarket in my book its a stock replacement adds very little gain on the older quads.

[hard one]

The exhaust on the two and four stroke dont even act the same!

Two strokes pipe is were you get your power gain and the silencer does nothing in the power depart ment except save weight


On the four stroke the type of header varies the power with the type of bend and the silencer helps alot. Say the header is a straight back with little back pressure you loose low end power so you will need a muffler with some back pressure.

The white bros exhaust system on a 300ex does give you 11 hp on the dyno.

i have a dg/white bros hybrid.it has a dg silencer,white bros head pipe,and whtebros jetkit,and whitebros filter.it pust out like 11.025 something.and wit the weight of the rider it gits like 10 hp to the rear wheels.

a 4 stroke pipe is ment to increase the amount of fuel and excess gas getting out the motor.thus making more fuel getting to the carbs faster.

a two strome pipe is made to get the power band to work faster and stay on longer.i have had a tecate,trx250r,and allso a 250ex with a pipe,a 250x with a pipe,and know a 400ex with a white bros pipe and it allso gets 11hp.dont bealive me call white bros at (714) 692-3404.

[lt250rm]

getting spanked by a blaster when riding a 250ex is not supprising. your talking about a low revving 4 stroke 250ex then a high revving 2stroke 200 blaster its not supprising. A 250cc 2stroke can run along with the 450r's.

[Dr89]

but i beleive if u bored it it would take the 300 till he caught ya

well then in that case it wouldnt be taking the 300 at all now would it? haha jk, i know what you mean. all those mods will help the 250 to out accelerate the 300 but with that stock rev limiter on there its top speed will remain the same.

[CHEVYZ]

Again, 11HP is unrealistic. On the 400EX, an 11 HP gain ( Of course, probably more... but just to say) would come from.... carb, exhaust, open airbox lid, big bore kit, headwork, ect. 11HP on a bike not even up to those standards is unrealistic. Be for real. You may see an actual over-all gain with a set-up like that of maybe 3-4 horsepower or so on a dyno ( Just guessing, I have seen them, but don't remember exact numbers).

With the 2 vs. 4 stroke pipe thing... I understand that you have bigger gains on a 2-stoke, that isn't what I was saying. What I was saying was that on average bikes today, the 4-strokes come highly restricted from the factory. Opening them up gives you gains that are pretty nice. The modern 2-strokes come from the factory with some generally good-flowing exhausts ( Mostly on dirtbikes I am refering to), so yes, power increase is notable... but it is also so on the 4-strokes. It sounded like you were saying that no gains at all come.... they do.

[250rider1]

ok all u that are saying that u r gettin 11 hp gains on ur 300's from a pipe and jetting alone are crazy. most systems on 450s dont get you that and the if you are gettin 11 hp then ur sayin that a piped 300 has about 24-25 hp. no way maybe about 3-4 on a 300. it takes a lot of work to pull 25 hp on a 250 or 300.

Yeah 11 rwhp is realistic an over all hp of 11 i belive but not an 11 hp gain. Especially not from a pipe! Unless you had like 1/4 exhaust on there or something.

And It might of sounded like I said that 4 strokes don't gain from pipes they do its just not as great as a 2stroke gains but if your talkinga 4 stroke with small exhaust then yes but some stuff like the older 4 strokes like the lt230s then no putting a pipe on that doesn't make a big difference maybe a 1/2 hp gain on the dyno but not a rider noticable thing.

of course you didn't lol, stock to stock a blaster could beat a 300 no problem

Sorry but Im living proof, 300ex will take a blaster. But not by much. They will run very close together but the 300ex stock off the showroom floor will take a blaster. I own both and Im am an avacant drag racer and have had both quads at the track and ran in an 1/8 mile and the 300ex took the win. Both machines stock.

weird 'cause when my blaster was stock, i raced a couple of friends 300's. not just one but a couple and i whooped everytime. (they were all stock btw) i even had a friend ride my blaster and i rode the 300 and the blaster still one.

i might be wrong about the 11hp but a blaster will not take a 300ex.i have a 250x and i raced a warrior and 2 blasters.the only thing that got me was the 350 warrior.so u are mistaken.

[96mojave]

ok i have had a blaster,warrior,300,and mojave,
this is how it goes (300vsblaster..blaster wins)(blastervswarrior...warrior wins)(300vsmojave mojave wins)
(mojavevsblaster...mojave wins)(mojavevswarrior...warrior wins)

mojave is stock other than 22in tires and shaved fenders i left the blaster win i hit 3rd but my friend that was racing me has about 40lbs on me

but i know for a fact a 300 stock will NOT BEAT a stock blaster
and definitly not my mojave...i dont kno why people think mojaves suck they are really good compared to its class and are capable of putting out 28+hp

[SET THE STAGE]

i've never lost against a mojave on my blaster.. maybe they were just bad riders? lol.

anyways back on topic. a 300 would stomp a 250ex. EASILY.

NAW THERE NOT BAD IAM JUST REAL GOOD lol

i raced a stock blaster and beat him, and my friend got an 01 with fmf fatty and power core 2 and i beat h

when i had the 300ex, i outed the mojave everytime...he was an equal rider, even giving him a start on a looooonnnnnnnggggg stretch of road, i was able to reel him in and pass him...


again, the 250ex will not compare to the 300ex...they are kinda like apples and oranges...

man 96mojave u are wrong.i had a 03 suzuki ozark and a stompt a mojave.then i raced the ozark and mojave against my 250x/300ex and i stompt them both.i rode a mojave and they are nice but are really out dated.sorry but the truth hurts.and i have seen a blaster beat the mojave to.and i also seen a blaster beat a warrior.why do u think most 250r's can hang with 450's and z400's?a mojave 4stroke mojave will not take a 200cc 2stroke blaster.mojave's are just a leasure 4stroke motor,yes they can be modid to race form but not stock.im a 4stroke man all the way but its time to see it for what its worth.thats why in mx bike racing they run 250cc 2stroke's vs.450cc 4stroke's.
