When you start noticing a loss of compression and / or power, it's time to replace your piston with a new one. This piston is the original spare part for the original cylinder, available in several sizes (A, B, C); the differences in size are tiny (0.01mm) so either get the same size as the original piston or one size up or down.

This is the size A piston. Including 12mm piston pin, piston ring and circlips.
