Fuel and Intake

Twin Air Filter's patented design, high quality materials and superior construction deliver unbeatable performance and protection - and make Twin Air Filters the hands-down choice of more World and National Champions than all other filters combined.
An air filter is your engine's only protection against the elements, and your stock filter isn't up to the task. Replace it with a Twin Air- the number 1 filter system proven on motocross tracks around the world.
Twin Air's fused layers of open-pore foam and fine inner foam trap even the smallest particles-without restricting airflow

Each kit contains float bowl gasket (or o-ring), float valve assembly (or float needle) and o-rings to rebuild one OEM carburetor body.

The Remote Fuel Mixture Screw is 5 inches longer than stock. This gives you plenty of length to easily mount in a convenient location. Will work with the stock BST Carburetor as well as the TM40 pumper Carburetor.

Designed for use with stock engines using either stock or aftermarket exhaust and air filters.
