The Keith Black KB292.010 1000cc Piston Set .010 Oversize is designed for a 3.188-inch bore and a 9:1 compression ratio. The hypereutectic alloy is cast in a permanent steel mold to produce lightweight pistons intended to support power, fuel economy, and durability.
The alloy’s low heat transfer helps keep the piston skirts cooler, minimizing expansion. High compression ring placement is designed to support increased power and economy while reducing detonation and increasing top-ring temperature.
This piston set fits 1972–1981 Harley-Davidson XL models. New pistons and rings should be broken in by running the engine at moderate speeds for at least 500 miles while avoiding excessive operation in lower gears. Vendor: Keith Black. SKU: 11-2241. Part number: KB292.010.
