When installing the 8219DA, always inspect your power valve for carbon buildup and ensure it moves freely. Replacing your small-end wrist pin bearing and using a fresh top-end gasket kit during installation is essential for a professional-grade engine refresh.\u003c\/p\u003e\n\u003ch3\u003eFitment List\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\" cellpadding=\"8\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eVehicle Brand\u003c\/th\u003e\n\u003cth\u003eVehicle Model\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2004-2005\u003c\/td\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003e300 EXC \/ EXC Six Days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2004-2005\u003c\/td\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003e300 MXC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eQ: Is this a Standard Size piston?\u003c\/b\u003e\u003cbr\u003eA: Yes, this is the 71.94mm piston designed for the standard 72.00mm bore.
