Carburettors & fuel injection

Pilot jets, main jets, needle jets, carburettor rebuild kits, fuel screws, float valves, throttle slides, and fuel injection components for two-stroke and four-stroke motocross bikes.
Two-stroke jetting is sensitive to altitude and temperature. A pilot jet that runs clean at sea level will run lean at 1000m and rich in cold weather. Keeping a set of jet sizes on hand means you tune at the track rather than wait for parts to arrive. All jets are marked by size for fast identification at a glance.
For fuel-injected bikes, this category covers throttle body components, injectors, and fuel system hardware where available.
