RFX carburettor tool

RFX offers this carburettor tool. The carburettor (or fuel injection) meters the mix of air and fuel entering the engine. Dedicated tools are used to adjust it: a vacuum gauge to balance several carburettors against each other, a gauge to read the size of a jet, a key to drain the float bowl, or an auxiliary tank that feeds the engine when the original tank is removed.

Why use a carburettor tool?

The benefits:

• Measured adjustments instead of setting things “by ear”: the result is precise and can be repeated exactly.
• Brass adaptors: they do not rust and do not mark the vacuum ports.
• Auxiliary tank: the engine runs with the tank removed, giving direct access to the carburettors or throttle bodies.

Why choose RFX?

RFX is a British brand of motocross and enduro parts and accessories.

When should you replace this tool?

A gauge that no longer returns to zero, dirty or low fluid in the vacuum gauge, an adaptor that lets air in or a key with a rounded profile: replace the part, otherwise the reading is wrong or the screw gets damaged.
