xc 400ex mods?

[exrider249]

What are some good mods for a 400ex? i do alot of woods riding and hill climbing. Right now my 400ex has 416 weisco piston and a hot rod crank. I am about to have the head ported and polished, stage 1 cam and kibblewhite valves and spring kit. What are some good mods to do? I want to get to run like a trx450r if thats possible.

go with a stage 2 not a stage 1. Other than that ur build is about the same as we all do. P
