• Yamaha SX 650 Carburetor Holder Socket Rubber Flange Intake Boots are made to run in all
    commonly available fuels, including those with alcohol. These parts are manufactured from high
    quality TSR compound and are designed to operate without metal covers or cans, yet will still
    support the carburetors. They will not give rapid age cracking or swelling. These rubber flanges
    use a steel insert plate, and are designed to run using a automotive type hose clamp.
