The warrior surprisingly has enough low end for a 350, so why lose more top end power??? This might be a good idea for a motor that has a cam installed but no high compression piston, or a top end favored setup. The difference is small when it is installed on the stock setup, but I imagine it would do much more as you increase the fuel and air consumption. It did help me wheelie a bit better with it installed, but as you ride more open orv routes it gets annoying.
