I am looking to get a little more power. I have read that there are a few mods that can be done. The bike already has an FMF muffler. I have read changing the exhaust cam to a YZ250F, Removing the grey wire from under the gas tank, changes it to YZ timing, and by replacing the throttle stop with a YZ stop. Has anyone done these mods, and what type of difference will I see.
