No, it is a fact unless you can do 60 mph in 300 feet your are not going to beat a modded prairie.
Not many sports have the horses to do it.
And these 70-78 mph claims top speed are just that, Claims.
In 300-500 feet a p700 with a dg3 or dynatek cdi will kick butt on any sport under 450 cc.


Last sport I raced was a the Honda ex 400 and it was a 5 length win and that was letting off'
He had new White Brother pipes and custom air box.
Your, Z440 never raced but I think
can not reach 60 mph in 300 feet. Your *** gets wiped by a utility.

 

you do know a 400ex is like the slowest sport quad out there nowa days... right? a z440 would have more than 5 lenths on a piped 400 ex.

 

LOL not to be a d!ck....but I would not hesitate to put $$$ on 300ft vs that Prairie in your sig, and thats no joke. I'd like to see that Prairie reach 60MPH on sand in 300ft. [img]i/expressions/face-icon-small-wink.gif[/img]

 

shee have 54 mm stroke and so piston bore,for a 350cc it is just
awsome powerband,i think to make a thumper act like a 2 stroke,you`'ll
need a even shorter stroke to make it feel like 13000-14000 rpm to
put the extra rotating mass of the 4 stroke in the long run for faster top speed,just as racer bike,but it would be very hard on a single cylinder thumper to do so,an 4 stroke need to spin twice as much
a 2 stroke to get all the power in the upper range and make great
flat power then.

 

So your saying that you can beat a banshee, Yfz450, 450R, but not a Raptor? Anything under 450cc? What are you talking about. Oh yeah I have a whole gear on a rap, so I guess I hit 85? no, maybe 78-80.

 

He is talking out his @ss! His mouth should know better!

 

come on hozed, is that a joke or what? A stock bore enginge vs. a modified one...hmm...wonder who's gonna win[img]i/expressions/face-icon-small-tongue.gif[/img][img]i/expressions/face-icon-small-confused.gif[/img]

 

this thread was started by a retard and I can't believe that all of yall are even posting in it. I'd also like to add that I have seen a few stock prarie 700's hand a few stock z400's their ***. The z400 is hardly a high performance quad stock. You need a 440 with the works just to break 40hp lol.

 

he said he beat a 400 ex by 5 lenghs.... there for a z440 would beat him.. as well as any YFZ...
obviously a z440 will beat a stock bore 400 ex... but that was my point.

 

Well if you agree a 400ex can be beat by a big bore p-700 twin modded, with ease I should say.
A 440 would be at best , a tie.
I have a co-worker that has a raptor and we have not been able to hook up yet.
I know he can beat my prairie top end but would love to race 1/8 mile.
He keeps avoiding me I think.
I have a dirt track and with mudlights and ITP series 6 rims can hit 60 mph in 300 feet.
This is with all the mods. Prior all I could do was 52 mph.
Big difference with dg3, degree key dg snorkel, and twinair filter



The original question of the thread " Is it possible to make a 4 stroke atv ACT EXACTLY like the 2 stroke Banshee atv? How?

All I know is a v-twin is as close as you can get on low end, power. It fires on two cylinders.
A Banshee fires once every revolution on a single cylinder. A 4 stroke fires every other revolution but when you have duals with a twin it is firing just as much as a single two stroke.
A v-8 or v-10, 12 etc. fires even more. Found in trucks and cars.
Cubic inches, cc has a lot to do with hp.
HP at rear wheels and weight is all that counts.
