How are the weisco 440 kit for z400. I am think of buy a quad with it in already

 

Make sure you look it over real well and ride it first. If they're already modded, they've usually been ridden hard compared to a plain old showroom condition stock one. But that's fine if it's been maintained 100%. You'll just have to look it over well. As for the kit, I've had no experience with them.

 

i think they are supposed to add a lot of torque to it. i would check it out thuroly(sp) first before getting it.

 

In some cases the mooded quad will be taken care of better then a stock quad. Regular oil changes/maintenance. It may have been rode harder, but thats what they are made for. With a stock quad some people dont change the oil, or even know how to check it.
