MOTION PRO carburettor tool

MOTION PRO 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 MOTION PRO?

Motion Pro was founded in California in 1984 by Chris Carter, a former Yamaha off-road test rider and ISDT gold medallist; having started out with control cables, the company now holds more than 30 patents.

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.
