To change your piston cylinder we advise you to watch the video tutorial below. You will need to have several tools to properly replace your piston cylinder AM6 (flat keys, BTR wrench, needle-nose plier, screwdriver...). The temperature sensor thread on the cylinder head is identical to the original AM6, for motorcycles with engines type AM6 Generic, KSR plan a probe adaptation AM6 or plug.
