Upgrade your Harley Davidson XL engine with the Wiseco 11-9886 883cc Forged Conversion Piston Kit. Designed for 1986 to 1995 Harley XL models, this kit features pistons that are .010 inches oversized and crafted from high silicone alloy, ensuring durability and high performance. The pistons are engineered with a 9.5:1 compression ratio, ideal for enhancing power output and efficiency while maintaining reliable operation. The forged construction provides superior strength and resistance to wear, making it suitable for both street and performance riding. This kit is specifically designed for a 3-1/2 inch bore, making it a perfect upgrade for stock engines or rebuilds requiring larger displacement. It is important to note that for 2009 and newer XL models, 1200cc cylinders are required for proper installation, which must be purchased separately. Proper break-in procedures recommend running the engine at moderate speeds for at least 500 miles, avoiding excessive low gear operation to ensure optimal piston and ring seating.
