Hello I'm new here.I own a stock 1996 Polaris Scrambler 400 4x4.I've had it for a couple years and ride mostly everyday.I know all about clutching with a pipe.I ride with a 660 raptor,YFZ,warrior,400ex and I'm tired of being left in the dust.What are the power and the top end gains from the RCR stage 1 kit?Thanks.
