Athena Gaskets Editorial Review
The Athena P400485100003 54mm 125cc Standard Bore Cylinder Kit is a good product overall, with customers happy about the increased performance and power it provides. However, some customers have had issues with installation and some parts being missing or defective. The kit comes with 3 gaskets but only the black base gasket is necessary, and polishing of some ports may be required. Some customers have encountered issues with dented head domes and incorrect power valves. The instructions are not clear and may be difficult to understand. Overall, the kit is a good purchase, but it requires careful inspection and modification before installation.
