Decompressor / Decompression Valve Set Piaggio Ciao and SI – Easy Starting Guaranteed

Is your Piaggio Ciao, Bravo, or SI moped having trouble starting, or is the decompression valve not closing properly anymore? The complete decompressor set brings back the usual starting comfort. If the old valve is leaking, your engine loses valuable compression, leading to noticeable loss of power and poor starting behavior. This set contains all the necessary components to completely renew the decompression unit on your cylinder head and ensure absolute sealing again.

Why a functioning decompression valve is essential

The decompression valve temporarily reduces the pressure in the cylinder when pulling the starter lever, allowing you to kickstart or start the moped with minimal effort. Once the engine is running, the valve must seal completely airtight. Our complete set is manufactured precisely to the original dimensions and fits perfectly for the classic Piaggio moped engines. By replacing it, you prevent annoying compression loss and ensure that your scooter is ready to go immediately.
