I have a full system on my bike i don't notice any difference. You find a difference with just the muffler

Yehh dude. But the muffler is half the size of the stocker. Deffore more snap and pick up. Sounds a billion times better aswell. Most difference in power ifound was the fully adjustable powervalve on tbe ktms. They come with 3 different springs. Im running the red spring which has a strong powerband

I found t sounds better that's about it

yehhhh i wouldnt expect hp gains with a pipe. jap 2 strokes are 1990's technology anyway. does yours have an adjustable powervalve?

nah i dont think so i bought some power reeds for it. you notice a massive difference when you chuck power reeds in it.

Yeh mine came stock with vforce 3 reed block

Yeah yzs would just have **** ones like all jap bikes.

I want!! considering trading in my efi '10 yz450 Some original photos have not been recovered yet.

Is that 2011 250 ?

My first one at 16 Sold the crappy 4 stroke. was so boring Loved that bike should of never sold it but needed a car Bought this thing recently love it but gotta sell it to pay a bit of **** off ---------- Post added 20-09-11 at 21:29 ---------- So any one that wants a cheap barely used 144 let me know. Its done under 20 hours since new! Some original photos have not been recovered yet.
