Best Honda 400ex Mods

Hi all, I am planing to buy a new 2007 Honda 400ex. I am getting a really good deal on it brand new from a dealer so i want to put a little money in to it. I am just not sure where to start. Any sugestions?

exhaust, jets, k & n air filter. then if you want more get a 440 big bore kit

Awsome thanks, any brands better than others? are nerf bars and skidd plates necicary?

i like nerf bars just for the safety cause my foot has gotten eaten by the tires a couple of times. as for brands i think its personal preference. so i like fmf. ive been happy with everything i use from them

cool, thanks

Best thing to start with is a pipe and intake IMO, remember, most mods require re-jetting. And skid plates are always a good idea.

Hello everyone!!.....newbee here....

....My son has an '05 EX..it has an Hmf slip-on,Hot Cams Stage I cam,a '04 XR400 head gasket,a '04 XR250 CDI and 'Motoman" high velocity porting...that's about 650.00..

The porting was done by me, so...that was like a freebie..sorta..

COmtnbabe, I highly recommend a foam filter over the K&N. Especially with how dusty the trails get here. Then add in our frequent water crossings. Skids and nerfs are huge in the mountains too. Curtis Sparks makes an amazing pipe for the 400's.

Ok Pipe, Jetting, Stage 3 rev limiter, stage 2 cam, maxxis holeshot tires, nerf bars, foam air filter, and an extra oil cooler mod. This is all on my 05 400 and it's pretty awesome If you do bore ht e 400 you will have heating problems to wear you dwon't even wanna put your legs next to the bike. do an extra oil cooler mod if you do bore it. Helps it run cooler and helps keep your engine alive a lot longer.

Why has no body mentioned anything about suspension yet? i think better shocks (like ones from 450R, or aftermarket) is one of the best mods you can do to something with such crappy stock suspension like the 400ex.
