Should i buy all the mods for the 400ex seperate or should i buy a package? the packages includes either big gun, pro cicuit t-4, bills thunder, yoshimura comp, white bros e-series? all those exhaust come with silencer, header pipe, kandn filter, dyno jet kit and outerwear cover? should i buy that or each part seperate? to check it out its at www.carbidesmotoworld.com its in the may 2004 issue of dirtwheels pg. 132

 

seperate. you dont need a 50$ assortment of jets. just two of em. k&n yes, pre filter yes, pipe yes. mid pipe yes. plug maybe. the kits are affordable if you take out the 50$ for the "kit of jets".
just my 2 cents.
shop around.. you got the internet and a calculator.

 

no offense but put the money towards a new quad if u like honda go for the 450r the 400ex is way outdated

 

1fast03z I hate to tell you but my 400 is not too much different than your 400z when did it come out like 99?! I think it is funny when people like you buy a quad, read a few posts and then all the sudden you are an expert on the theory of quad evolution... lol

 

Booth, it's downright hilarious. They are close enough it boils down to the rider.

I've asked this before and never got a decent answer. What exactly is so technologically advanced about the Z and so what is so outdated about the EX?

 

not much IMO. Z has double overhead cam, liquid cooled. 400ex single overhead cam, aircooled. double overhead camp = more power but more weight, single overhead cam = less weight, less power. So ya it really does boil down to the rider [img]i/expressions/face-icon-small-smile.gif[/img]

 

Liquid cooling is new technology? Ex 4-valves and Z 4-valves. A dohc won't create more power than a sohc, just capable of producing power over a wider range. The pro to a dohc is that IF you use variable valve timing, it can translate into a longer torque curve. Very important for high reving engines. If it turned more rpms, I'd be more likely to agree with the dohc being an advantage. Just my opinion.

 

it might be outdated but it was an awsome quad then, and it still is now

 

It may be outdated but just like the bunny it just keeps going and going.
