Part #: 910-0203

This cylinder and piston kit for S&S 106" stroker kits may be used to replace the stock cylinders, when building a 106" stroker engine. Also handy for repair of an existing 106" stroker engine. Cylinders are finished with a durable wrinkle black powder coat that matches the stock engine finish. Kit includes S&S 3-7/8" bore cylinders and forged stroker pistons for 4-1/2" stroke flywheels, rings, wrist pins, and head and base gaskets. For best performance, appropriate camshafts, performance air cleaner, performance exhaust and fuel system tuning are required.

MIA's Description

The S&S Cycle 3-7/8" Cylinder and Piston Kit (MPN 910-0203) is engineered to enhance engine displacement for Harley-Davidson motorcycles. It is specifically compatible with 103" stock engines or those previously upgraded with factory 95" kits. This kit allows for the use of either stock or S&S cylinder heads. For fuel-injected models, a recalibration of the fuel-injection system is mandatory after installation. Installation of this kit is recommended for skilled technicians, who are responsible for verifying all clearances and assembly specifications to ensure proper fitment and operation. This kit is not suitable for Twin Cooled motors.
