Show original supplier description
The S&S Cycle 96" Big Bore Kit is engineered to enhance the performance of your motorcycle's engine by increasing its displacement. The comprehensive kit includes everything needed for the upgrade: the cylinders themselves, pistons, piston rings, and all essential gaskets, such as head, base, and exhaust gaskets. This ensures a complete installation solution. Proudly manufactured in the U.S.A., this big bore kit represents a significant step in engine modification. Installation of this kit requires a skilled technician due to the precision involved. It is the assembler's responsibility to meticulously check all clearances and adhere to assembly specifications. Importantly, this kit requires crankcase boring for proper installation, a procedure that must be performed by a qualified professional.
