    Tip of the day: Waterbox Mod

    I've been getting a lot of emails lately asking how to do this mod so i figured i would post it again.

    This is called the Rotax Racing waterbox mod. Its said to produce a 4 horsepower gain on the dyno.

    I was forced to do this mod after my baffle exploded into pieces. Oh well. Will be testing as soon as the waterbox comes back. My wife asked why I wanted to make it louder, but I told her I had no choice unless I buy a new one for $430.00. Hey maybe I could cause something else to break, and just tell me wife the only way to fix it is to go to a stage 11? "Honey the battery is dead! I need to go to a stage 11 so this never happens again"
