DAMAGED: Somewhere along the line, this kit was dropped hard enough to dent the cylinder spigot so that it is no longer round. The piston will not pass through the bottom of the cylinder. The piston, piston rings, piston pin, and piston pin circlips are not damaged. There is brown packing tape residue on the cylinder as shown in the photo.
This is one of the last version (manufactured ~2015/2016) Gilardoni V7 Sport and 750S cylinder and pistonset (size B) with 82.5mm bore. These original dimension piston and cylinder kitsyield standard compression and 749cc and are specifically designed for Moto GuzziV7 Sport and 750S.
