Go with the Z all the way........

If it is not fast enough stock, a pipe and jet kit will have you clearing any jump on just about any track .....

 

i whould go the z400 because it will be better for you on the track and it will do just fine on trails.

 

Z.
My dvx has the same motor and frame and suspension as the Z and I love it. I have yet to bottom out my suspension hitting like 40 foot jumps. My buddy has a 400ex, and it bottomed out the first jump he hit, and it was like a 10 foot gap. It doesn't compare, anywhere. Except for the reliability. Which yeah know, I have owned my DVX for almost 2 years, and never a problem. And yeah, if it's not fast enough for yeah, high flow air filter, stage 2 jetkit, and high performance exhaust.

 

ok well im pretty sure im going to go with the Z because all i hear is good things about it and i also hear that the 400ex doesnt respond to upgrades as well as the Z

 

also what would be the first thing to do when i want to upgrade? pipes airfilters something about a airbox what? and i also know that i have to rejet but how do i know what to rejet it to?

 

I would get a full system exhaust. Yosh made an oval high airflow pipe for Kawasaki, the current pipe I have on my DVX, the best pipe any of my buddies have ever seen. I added almost 12 hp! and then a K&N airfilter. and as for the jetting, youjust have to play with it.

any good shop will beable to tell you what jet size you need depending on what pipe, air filter you get

 

is there anything i should do when i get it? alot of people say something about taking the airbox off

 

you can buy a K&N air intake so you can take the lid off of your air box. maybe try to get a pipe and air filter when you buy the quad it is usaly alot cheaper if you buy them with the bike.

 

idk i could try but i dont want to over due it i wanna get a feel for the bike b4 i get a pipe or something that will change the performance by alot but how much does a K&N run becuase i looked and i see some filters for amost 150 then some for 50
