V-Twin - 11-2273 - 88 inch Twin Cam Piston Set .030

Description

Keith Black piston set is .030 oversize and is for a 3-3/4" bore. Piston set has a compression of 10.6:1 and includes rings.
The Keith Black 390 hypereutectic alloy is cast in a permanent steel mold which makes it possible to build a light weight piston that makes more power and uses less fuel and lasts longer. Pistons are .030 oversize, for a 3-3/4" bore and has a 10.6:1 compression ratio. The low heat transfer of the alloy keeps the skirts cool so piston expansion is minimal. The combination of a low heat transfer piston alloy and high compression ring placement increases power and economy. The high ring placement alone reduces detonation and increases the top ring temperature. **Note: Run engine at moderate speeds for at least 500 miles, avoiding excessive running in lower gears, in order to properly break-in new pistons and rings.
