i need to know what u guys think about both these quads i just herd that the z400 isnt realy all that faster than the 400ex or at allfaster

 

any one

 

The z400 is alittle faster stock. One thing you might want to check into with the z/kfx 400's is if they are still having problems with the frames cracking. I know the 2003's had bad frames and were supposed to be fixed in 04, but I think I heard of a 04 frame breaking also. Either way you'll have a blast on what ever quad you get.

Z400 is faster for sure, its smoother, it shifts nicer (not that the Honda is bad), softer seat, easier to pull clutch, reverse, liquid cooling. I know that many have said that the Z is barely faster than a 400ex, I own both, my buddies own more of each, I have much experience on both, riding, wrenching, and hopping up. I have a piped, filtered, and jetted Z, that will run with a nicely built ex. I have a buddy with a DUncan 440, its a few seasons old, and the z is faster. I have since added a carb, cams, diff comp ratio, its Raptor fast now.
The ex is a nice machine, it feels lighter (they are within pounds), its cheaper to buy parts for, ans cheaper to buy.
I you don't mind the diff in price, no question, get the Z.
I have had zero probs w/ the frame issues. They have beefed up the 04's. I have one of the very first ones, not a problem. Some have had axle problems, I even have spacers, no problems. Usually my woman rides it, but trust me, I have ridden it hard too.

 

so if i get a 400ex rather than the z and put all kinds of mods on it will it keep up with the z with the same mods

 

No, mod for mod, a 400ex is slower (up a hill, in a drag, nothing about a track, thats all rider on these two quads)

 

i heard the z400 is a little faster (thats what im getting) i dont have to worry about the frame cracking because i am going to make it tuffer by making brackets and other supports to make if touffer.....

 

how fast is the z400 and 400ex

 

Are you talking top speed?
They are the same, don't worry about top speed.

 

i tohught the z was faster by a littlebecause to me that means a lot for drag racing
