500 bucks to spend

[Deadmeat]

Got $500 to spend what should i get for my '06 400ex looking for more top end and more power.

[ImWhite]

id say pipe,filter and jetted to start it off

[TRX400-06]

Pipe, Nerfs Def, Jet, air filter and you'll be good to go. If you dont mind you could probably get a really good deal for a pipe from some one on here.

[400exstud]

If you don't race, the best bang for your buck would probably be a slip-on pipe, cam, air filter, and jets.

i would start off at full pipe, filter, jet it, and then before doing motor mods, do suspension.

[Jared Hamilton]

pipe stage 2 cam and a 11;1 compression piston

[fitethesystom]

I could use $500 right about now lol

[Deadmeat]

sounds definately like pipe and jetting what jetting do u suggest and pipe slip on and full?

[2006-400ex]

ide go with HMF Full or Curtis Sparks x-6

[TRX23rider]

id go with an hmf slip on or full

[250x_kyle]

well id say if it looks like a 450r get ride of the lites and get a hood. if u like the lights keep them. id deffinatly get nerfs a hmfmufler a airfilter and try to jet

[Unverfehrt400ex]

slip on pipe and a filter, maby some nerfs and tires are a great mod too

[speedracer13t]

Get rid of the stock bumper, PRM summit if you ride the woods, then filter and pipe

[Young_Gun1]

full pipe, air filter, jets all at the same time probly if u do filter or pipe u need to jet though. idk with the pipe but i have a spraks x-4 and it runs great so maybe an x-6
tires are a good thing to get to
your going to have to look at prices if u can only spend $500

[TRX400-06]

I am big on nerfs since i shattered my tibia and febula. By a used set or something. I would diffinately by some though. I can just now start walking and riding again.

[blackwell17]

for 500 i dont think you can get a full exhaust , filter, and jet kit... you may have to settle for a slip on for now

[GOTFEAR]

A night out on the town

[prepracing]

for a stock engine all you need is a slipon pipe, the full system can actually cause a stock motor to lose HP becuase of loss of backpressure

[Deadmeat]

k got a k&n airbox lid, and looking at nerfs that are black powdercoated with red netting, prolly gonna get a slip on not sure which one yet and the air here is pretty lean not sure how much bigger to go on the jetting
