What mods next?

[jsmith2232]

ive got a 400 ex it has fmf powerbomb header, fmf powercore pipe, k&n filter and jet kit, rev box. I can hold my own against most other ex's but what would be the next thing on the list for getting more out of my machine.

id reccomend a bigger cam, preferably a hotcams stage 1, and 14/39 gearing.

i would get a higher compression piston and a cam. you will notice a very nice gain

[400Rider022]

cam and high comp piston:devil:

[prepracing]

depends on what kind of riding you do, suspension work maybe ? If your ride is more comfortable you have less fatigue and can ride harder and faster
