The 87-92 LT250R quadracer did have a powervalve as well as the tecate.

And while a powervalve is meant to increase low end power, it also allows for a larger exhaust port thus increasing top end. With that said when it comes to stock port dimensions a good pipe has more to do with where the powerband is than a powervalve.

Yes the zilla was a bit weak for a 500 is stock form, but with porting and pipe it can make some serious power. And it can still have the low end a banshee can only dream of.

The overall best 2-stroke quad was the TRX250R, and that is simply because it's chassis design wasn't rivalved until the YFZ450 and TRX450R came around.

 

quad motor box stock gasgas300...hands down,ive smoked sevral 250r's with aftermarket top ends,the 300 has awsome power stock,can be modded to 60hp for under a grand,ultra smoth gear box,and can be lugged like a 4-stroke.and its reliable
the ktm 380 really impressed me,has the grunt of a 500 but revs quicker

 

All this talk about the 250R, ... how about you guys put your money where your mouth is [img]i/expressions/face-icon-small-wink.gif[/img]. You can buy a brand new 2005 Honda 250R from Service Honda. The picture on that web site is old though, because the current 250R from Service Honda has the new style 450R plastic on it.

I've never seen a gasgas fourwheeler how do they run? and they are 2 stroke they look really nice

-oh yah you have really nice quads that yzf600 is that a R6 engine in that?

 

The yzf600r motor is a detuned R6 motor, yes.

 

the yzf600 is more of a tuned up version of the fzr600,.the r6 is a completely differnt motor with more power than the other two

 

Your right, the R6 has a much higher redline and such, so I guess it would be a different motor alltogether.

Good call.

 

I have to say that 80's cr500 motors were the $hit.

80's 250R's were the $hit.


Now - can you even still buy a four-stroke that you can ride year-round?


period.

 

i can ride my four stroke year-round so i dont get what you mean

 

He just means that in california the green/redsticker laws are getting tighter.

I have a 93 KX500 and 97 Banshee and can ride them year round, but if you buy a brand new banshee or whatever, they have a red sticker meaning
you can only ride half of the year. (LAME)
