    never heard of the 800 trick but rivera if you want to buy an 800 one cheap to try I have one. Im on Long island so it shouldn't be expensive to ship i would think.

    yea why not, its smaller than a 1300 waterbox for sure, holds less water / quicker hole shot

    Thats a new one to me... never tried an 800 waterbox, but Im sure the OGs have at some point.

    The biggest problem with changing the waterbox is back pressure. 2 strokes need back pressure for scavenging of exhaust gases. The more open or loud the exhaust, the less rpms you will make on top end. The more backpressure, the more rpms on top. Open exhausts will produce more bottom end and midrange punch, but suffer on top.
