SKU:11-9887
Upgrade your Harley Davidson XL engine with the Wiseco 11-9887 Forged Conversion Piston Kit, designed specifically for models from 1986 to 1995. This kit features pistons forged from high-silicone alloy, providing enhanced strength and durability for high-performance applications. The pistons are oversize by .020 inch, suitable for a 3-1/2 inch bore, and are engineered to deliver a compression ratio of 9.5:1, optimizing power output and engine efficiency. These pistons are ideal for riders seeking reliable performance and longevity in their engine rebuilds or upgrades.
Proper installation and break-in are crucial for maximizing piston life and engine performance. It is recommended to run the engine at moderate speeds for at least 500 miles, avoiding excessive running in lower gears during this period. This helps ensure rings seat properly and the pistons settle into their optimal operating condition. For detailed installation instructions, refer to the official Wiseco piston fitting guide linked in the product information.
This kit does not include cylinders and is intended for use with separate 1200cc cylinders for 2009 and newer models, as these cannot be bored out to 1200cc from 883cc cylinders. It is compatible with a range of Harley Davidson XL models from 1986 through 1995, providing a versatile upgrade for vintage and early models. The pistons are made in the USA, ensuring quality craftsmanship and reliable performance.
For a complete rebuild, consider pairing this piston kit with recommended accessories such as piston rings and ring compressors. The Wiseco .020 inch oversize piston rings are sold separately, along with a ring compressor tool kit and connecting rod clamping tools, facilitating easier installation and optimal piston sealing. Whether you're performing a rebuild or a performance upgrade, the Wiseco Forged Conversion Piston Kit offers a high-quality solution for enhancing your Harley's engine performance and durability.
