400ex rebuild

[smjiil]

Hey, I have a 2001 400ex and am wanting to freshen up the motor and put some real power in the top end. I am not wanting to bore it yet cause the cylinder is still good shape. The package i am thinking about is 11:1 piston, port the head, stage 2 hotcam maybe another cam depending on your suggestions. Tell me if i will like this package or please reccomend another one. Thanks

You should also consider exhaust, jet kit and an aftermarket air filter.

And Cometic Gaskets kit.
