If the carburettor on your Aprilia Scarabeo 100 4T, Piaggio Zip 100 4T, Fly 100 4T and Free 100 4T no longer runs well, the cause may be the diaphragm: this part reproduces its shape and function, so the engine can work normally again.

When to replace it

Rubber ages, hardens or cuts along the edges. Air and mixture are then no longer metered correctly: hard starting, uneven idle or an engine that will not start. A new diaphragm fixes the problem in a few minutes of work.

Features

• Shape and function like the original diaphragm
• Simple fit, no modifications
• Needle not included: reuse the standard one
• Affordable price

Compatibility

Fitting tips

Open the carburettor, replace the diaphragm making sure it sits correctly in its seat, close up and refit with the standard needle.
