70cc cast iron cylinder kit from Naraku for Morini engines.
The Naraku piston is supplied with a molybdenum coating which protects both cylinder and piston during the running in process, this coating usually dissolves after time.
This cylinder is suitable for use with original and performance exhaust systems. If using the original carburettor you will need to upjet approx 7-10% but we do recommend using a 17.5 - 19mm carburettor for optimum performance.
Supplied as shown on the product photo. Original cylinder head can be used, but 70cc cylinder head is recommended (to purchase separately).
This kit is ideal for everyday use with significant power gains on acceleration.
