Complete cylinder kit from Naraku with all gaskets and small parts for assembly. This cylinder delivers with its 150cc the same engine power as the original cylinders of 150cc GY6 and Kymco AC engines and is therefore excellent as a low-cost replacement for defects in the original. The Naraku cylinder kit can also be used to increase the power of 125cc GY6 and Kymco AC engines. Overall, the build quality really stands out from the original Chinese replacement parts, making this Naraku kit a very good choice when a good replacement cylinder is needed.AI-translation
