This carburettor is suitable for replacements or tuning projects: check compatibility with your engine, connection diameter, and necessary accessories (clamps, intake manifolds, gaskets). Proper adjustment is crucial: jet adaptation according to altitude, fuel, and exhaust, and checking the tightness of hoses. Fine tuning ensures a consistent throttle response and controlled fuelling.

Practical advice: entrust the installation and tuning to a workshop if you are not equipped, plan for road or dyno testing and adjustments, and check the availability of Keihin spare parts for regular maintenance.
