Sizes from A-E.
The piston needs changing every 150 hours. At this time, the cylinder will benefit from a slightly larger piston than the original size. Per the instructions on pages 108-117 of the maintenance manual, the cylinder will need measuring with a bore gauge. Replacing with the original size may, in some cases, bring a gap relationship between cylinder and piston under the max of 0.15mm, but this tolerance will not make the next 150 hours.
Refer to the Vittorazi Maintenance Manual for detailed fitting instructions.
