[img]i/expressions/face-icon-small-blush.gif[/img] They weren't no 2005 when my ex was stock so i didn't race them ...

 

i wasn't trying to be a ahole either just pointing out that theres lots of bench racing that goes on here.these simple type of ??? get ask all the time.a simple search can give you lots of info also and people don't use the search button to find easy anwser too their ????

 

blackbird..did you notice I said both of them had different exhaust on them..every quad repsonds different to different mods..so i was just askign because where the Z and ex are SO close stock...

 

yep i saw that .but like you said thier so close that it going to come down to rider.but the z opens up a lot more when you but a full pipe on .the ex 400 will not get the gains the z400 gets with a full pipe

 

I've heard the same thing about the z responding a lot better to mods. Thanks to information I've gatehered here and many other places over the last 6 months I had decided to buy a z and I hadn't even ridden one yet. I had ridden a couple ex's. Now that I took a ride on one this weekend I know I'm definetely getting one!! Smooth ride and smooth power delivery, I think it's so smooth you don't even expect the power to be there but it is. I've ridden yfz's and obviously there faster but i'd take this one over the yfz let alone the ex. There's a lot more to which quad is faster than just hp numbers. The obvious one would be the rider. Then faster how? On the track? In the woods? In a drag? Then the same rider could be slower on the "faster" quad just 'cause he/she is more comfortable. But my final decision would be the z. I'm going to get the 06 z and install an hmf s/o jet it and high flow air cleaner. And ya know what? My little brother will still smoke me on his 01 ex!! Even if I was on my other brother's yfz.
