Ive heard of taking the air box lid off for more power. When I tried it on my stock Z400, it ran very bad. Whats the trick? Carb ajustments? I would like to beef my rig up enough to hang with my buds 450ex. What are some good mods I can do, that wont hurt my wallet too bad? What would about $500 worth of go fast goodies do for me?

 

you could build an intake like the one on my photo page it is cheap and adds a good amount of power.

 

You need to re-jet the carb. to compensate for more air flow...........

 

The fact that it ran bad with the lid off, just proves that it will do a lot to increase your performance, AFTER YOU GET A REJET! You increased the amount of air, now you need to increase the amount of fuel to match it!

I like this lid (http://www.ehsracing.com/), because it has an Outerwears that keeps a lot of the dirt out of your box, yet flows huge amounts of air.

 

for less than $300.00 I added a White Bros. (E) series slip on, K&N with outer wear removed the air-box lid and re-jetted and it made an honest to god seat of the pants differnce especially in the low and mid range. If that can make such a diff on my ex's it should do wonders for your z.

 

Get exhaust slip-on mufler ,rejet ,get air box lid cover from outerware and twinair ,air filter , rev-limiterand youll spank that 450ex.all for around 500.oo bucks.

 

Yea, you needa jet yur carb...

 

Go to albaaction.com and look at their performance packages, they offer FMF and ALBA, they are jets, full exhaust k&n filter and adapter, and outerware. This for around 500(480 for the ALBA i think) I am saving up for one of these for my z400 i just dont know which one yet.

 

for $500, get an HMF full exhuast or a Yoshimura slip-on pipe. Then throw the rest at a performance CDI.

 

You could get a 440 kit for $260 from wiseco, if not that, get a pipe, filter, and rejet it, but I don't think you could keep up with the R, its just to fast. But if you get the 440 you may have a good chance, but you or some one has to install it profesionally.
