think i went to far with the 400ex rebuild
i rebuilt me freinds 400ex. went .80 over with 10:1 compression and a stage one cam and slight port job and curtis sparks exhaust. tons of power but cant keep the front end down. almost untrailble. any time you touch the throttle she stands right up even with my 240lbs a$$ over the handle bars. my buddy only weighs 180. i may try going up a tooth on the front sprocket and see what that brings.

you can never have too much........we have built several setups similar to that and we always want more. yes, the front end is lighter but it is faster and that is what we want. by running aftermarket shocks and tires the front end will stay down much better.

Even with the stock engine, the 400ex benefits from a +1 swingarm. You might try going with a +2. You should see a huge improvement. Do not go +1 though on the a-arms or it will make the front-end feel even lighter.
