Currently LED is working on a 430 Puma kit. This 430 Puma kit is for a Honda TRX 250R with an 85mm bore and 76mm stroke crank shaft. All though the Puma will make great power with out porting, on this cylinder we are doing port work to improve transfer and exhaust port shapes. We are improving the scavenging to improve acceleration and increasing exhaust port area to increase peak horsepower. On this built we are using the oversize exhaust manifold. This engine will use on of our large volume drag pipes. The cases have also been machined to accommodate the Puma cylinder.
