In order to make it easy for you to enjoy the first step in customizing your engine, we have included a reinforced oil pump, reinforced clutch, and reinforced cam chain that must be replaced when upgrading the bore. This is a great value kit that can be safely recommended to customers who are doing bore ups for the first time. A simple bore up kit that uses a normal cylinder head. Ideal for first-time bore ups, you can easily experience increasing torque and power in the low and medium speed range. Lightweight aluminum alloy, highly durable cast iron sleeve cylinder & piston set. The cylinder uses large fins and exhibits a high cooling effect. In the case of the 88cc kit (φ52 cylinder), the cylinder can be reused and later upgraded to a hyper head, and by replacing the crankshaft, it can be upgraded to a maximum of 110cc specification. Please use it as the first step in 4 mini customization.
