Basically "Clay and shape for a Smaller/Velocity Stacked Intake Ports to gain 7% more power"
There is someone with a KLR650 that claims their "Big Bore/fully built engine" is making close to 90 horsepower (at the wheel) with the help of "Small/Velocity Stack Intake Porting"... the power/numbers I feel are a bit suspect due to the Dyno they are using... seen too many "extremely happy customers" when they get numbers back on their (stock) bikes/cars...
