Notes: We recommend using this tuning cylinder in conjunction with a larger exhaust and a larger carburetor. This racing cylinder may still contain residues from the manufacturing process. For this reason, the cylinder should be cleaned with compressed air or brake cleaner before installation. This should be between 0.15 - 0.4 mm to prevent the piston from jamming.
