Note that no modifications to the stator hold down bolts or to the SKUSA plate is permitted. No other modification to any of the ignition components that changes static timing is permitted beyond what the SKUSA plate allows. This also applies to the rotor, crankshaft, keys and keyways.

SRS CR125 Power Valve Plug Set - 2001
SKU: SKU34846

Top performing, precision, investment cast power valve plugs for the 2001 CR125 cylinder are now available from SRS Engines.

The shape of the exhaust duct in the 2001 cylinder is critical to power production. The stock 2001 power valve shape sacrifices peak power to give the engine a broad motocross power band that has good response as low as 6000 rpm. Since stock 125 shifter karts operate above11000 rpm most of the time, they can ignore low rpm power in trade for power gains above 11000 rpm.

SRS has identified the duct shapes in the 2001 cylinder that give top level performance in the shifter kart rpm range. These shapes have been captured with computer solid modeling techniques and incorporated into the SRS 2001 CR125 power valve plugs.

A precision investment casting process was used to preserve the shapes of the solid models with a high degree of accuracy in the production power valve plugs. When the plugs are installed in the cylinder and properly blended for smooth transitions between the cylinder and plugs, the maximum power potential of the stock 2001 cylinder can be achieved.
