This cylinder kit from MXT contains a grey cast iron cylinder with 70 ccm displacement as well as the matching cylinder head for horizontal, air-cooled two-stroke engines of the Minarelli AC type. Included in the scope of delivery are the cylinder, cylinder head, aluminum piston (CNC-machined) with arrow marking for installation direction, piston rings, piston clips, 10 mm piston pin, cylinder base gasket and cylinder head gasket.

Important Note:

• Increasing the displacement to 70 ccm leads to the expiration of the operating permit for vehicles with 50 ccm approval - operation on public roads is no longer permitted in this case.

Product Features:

• Grey cast iron cylinder 70 ccm for horizontal Minarelli AC engines - displacement increase compared to the standard cylinder
• Timing angles designed for low to medium speeds - power increase already in the lower speed range
• Grey cast iron version allows for re-honing of the cylinder liner if necessary after carburetor problems
• A carburetor with a 17.5 mm bore is recommended for optimal function
• Operation with standard exhaust system possible - can also be used in combination with a sport exhaust system
• Cylinder and cylinder head are matched to each other - no separate component alignment required
• Piston with arrow marking on the piston crown - arrow must point towards the exhaust side

The low timing angles of the cylinder shift the usable speed range towards everyday operation; the recommended 17.5 mm carburetor ensures that the mixture preparation fits the enlarged bore and the internal cooling of the piston is maintained.

Assembly and Application Notes:

• Important Note: Increasing the displacement to 70 ccm voids the operating permit for vehicles with 50 ccm approval - check the legal situation for the planned intended use before assembly.
• The piston is marked with an arrow on the piston crown, which must point towards the exhaust side.
• A carburetor with a 17.5 mm bore is recommended for optimal operation; replace all gaskets during installation and adhere to the tightening torques according to manufacturer specifications.

Note on Inspection Before Purchase:

• Before purchase, check the engine type (Minarelli horizontal AC) and clarify the planned intended use - operation on public roads with 50 ccm approved vehicles is no longer permitted after the displacement increase.
