Keith Black KB264.030 1200cc Piston Set .030 Oversize

Keith black flat top piston set is .030 oversize with a 9.0:1 compression ratio includes rings.

The Keith Black KB264.030 1200cc Piston Set is manufactured from hypereutectic alloy cast in a permanent steel mold. This construction supports a lightweight piston design intended to help produce more power, improve fuel economy, and provide long-lasting service.

This .030 oversize piston set is designed for a 3.528-inch bore and features a 9:1 compression ratio. The alloy’s low heat transfer helps keep the skirts cooler, minimizing piston expansion. Combined with high compression ring placement, the design supports improved power and economy while helping reduce detonation and increase top ring temperature.

Keith Black KB264.030 pistons fit 1988–1997 Harley-Davidson XL applications as listed in the product data. New pistons and rings should be broken in by operating the engine at moderate speeds for at least 500 miles and avoiding excessive operation in lower gears. Refer to the supplied piston installation guide for installation information.
