It rotates with the crankshaft to open and close the intake ports at the correct interval, which directly affects how the engine breathes and runs. It is intended for riders and mechanics servicing or rebuilding a 720 engine in a GS hull.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision-cut port openings timed for the 720 engine's intake sequence\u003c\/li\u003e\n\u003cli\u003eFlat, true surface for a clean seal against the rotary valve cover\u003c\/li\u003e\n\u003cli\u003eConstruction suited to continuous contact with fuel and oil mist\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct replacement for the stock rotary valve disc\u003c\/li\u003e\n\u003cli\u003eBalanced to spin with the crankshaft without adding vibration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Sea-Doo GS 720, 1998\u003c\/li\u003e\n\u003cli\u003efor Sea-Doo GS 720, 1999\u003c\/li\u003e\n\u003cli\u003efor Sea-Doo GS 720, 2000\u003c\/li\u003e\n\u003cli\u003efor Sea-Doo GS 720, 2001\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTop-end and full engine rebuilds on 720-powered GS watercraft\u003c\/li\u003e\n\u003cli\u003eRestoring intake timing after a valve or cover failure\u003c\/li\u003e\n\u003cli\u003eRoutine refresh during off-season maintenance\u003c\/li\u003e\n\u003cli\u003eShop service work on 1998 to 2001 GS models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRotary Valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e720\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel Years\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1998-2001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVehicle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSea-Doo GS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Does the rotary valve need to be timed when installed? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, the disc has a specific opening point relative to the crankshaft, so it must be indexed correctly during assembly.
