All Balls Racing – Chassis Bearings & Hardware - KTM / Husqvarna / GasGas, including the 09-10 SX 450 ATV Carburetor Mid Body/Jet Block Gasket Kit and Master Cylinder Rebuild Kit Clutch for the 2008 XC 450 ATV and 09-10 SX 450 ATV. These Austrian-built quads share hard parts with the dirt bike line, which is why the small service items get scarce and why a correct gasket or seal kit on the shelf saves a race weekend. The carburetor mid body and jet block gaskets seal the fuel circuits between the carb halves, so a hardened gasket means a lean stumble, an air leak or fuel weeping down the engine. A hydraulic clutch that fades, drags or pulls to the bar means the master cylinder piston seals have swollen, and a master cylinder rebuild kit brings back a firm, repeatable lever with full disengagement instead of grinding shifts. All pieces are dimensioned to the original bore and groove sizes, using seal compounds that stand up to brake fluid, pump gas and the heat cycles of a race quad. Give us the year, model and whether the part is clutch or brake side, and we will confirm the right KTM ATV rebuild kit before you order.
