Restore reliable performance in compatible Harley-Davidson overhead valve engines with the Motorshop 11-1652 Replica 74-Inch Overhead Valve Piston Set in .005 oversize. Designed for engine rebuilding applications, this piston set provides a practical replacement solution for 1941–1950 Harley-Davidson FL models when cylinder machining and piston sizing require an oversize component. Verify engine specifications, bore measurements, and required clearances before installation to ensure proper fit and performance.
The Motorshop 11-1652 piston set is supplied as a kit and is intended for experienced builders and professional mechanics performing internal engine service. Proper installation procedures, ring preparation, cylinder honing, and clearance checks are essential for achieving dependable results. Pair this set with the appropriate .005 oversize piston ring set, such as Motorshop 11-1744, and use suitable assembly tools to support accurate installation.
After assembly, follow the recommended break-in procedure carefully. Run the engine at moderate speeds for at least 500 miles, avoiding excessive operation in lower gears, to allow the new pistons and rings to seat correctly. Always follow the engine manufacturer’s service guidance and confirm all components are compatible before beginning the rebuild. Made in Taiwan, this Motorshop piston set is a focused replacement component for maintaining classic Harley-Davidson FL engine assemblies.
