Improving 400EX ground clearance

Here is my experience. Holeshot XCT's (23" front/22" rear) are supposed to be the hot setup for desert racing. On the 400EX they give the bike a little bit of a tall and tippy feel, but it isn't so terrible that I couldn't live with it, as long as I run rims with a greater offset so that widens the bike some. I went down a tooth in front to compensate for the gearing change, and I have to say that it was way to much! Any slight blip of the throtle would have the front end up in the air. It would wheelie powering out of turns, and I lost steering control.
I know everybody likes to do the easy fix and just change out the front sprocket (because you don't need a longer chain and a sprocket is cheap!), but in my experience it was to much. A better fix is to go one or maybe two teeth bigger in back (one tooth in front = three in back). I can go one tooth without a longer chain, and depending on what swingarm skid plate you have, you may not have clearance for two teeth.

i think 1 tooth in the front equals about 2.5 in the rear.
