43 mm tuning cast cylinder with 63 cc and 10 mm KoBo suitable for your Piaggio Si, Bravo 2 and 3 as well as Grillo moped / moped.
All necessary parts are included in the scope of delivery, including the matching cylinder head for installation.
Notes: We recommend using this tuning cylinder in conjunction with a larger exhaust and a larger carburetor. This racing cylinder may still have residue from the manufacturing process. Therefore, the cylinder should be cleaned with compressed air or brake cleaner before installation.
Before installation, check the piston ring joint using a blade gauge. This should be between 0.15 - 0.4 mm to prevent the piston from jamming. Please observe the installation direction when assembling. The piston is inserted with the arrow pointing towards the outlet on the exhaust side.
