Restore the top-end performance of your ATV with the Namura Top End Kit, manufacturer part number NA-20001-6K. This kit features a 68.47 mm piston with a +1.50 mm oversize specification and an 11:1 compression ratio, providing a comprehensive replacement solution for compatible Kawasaki KLF220 Bayou engines. The kit includes the piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit for convenient engine rebuilding.
The piston is manufactured using a hypereutectic casting process that increases silicon content for reduced expansion, improved wear resistance, and reliable operation at elevated cylinder temperatures. Its MOS2 Teflon and molybdenum-coated skirts use a rolled-on application process designed to create a stronger bond than conventional spray-on coatings. This coating helps reduce friction, improve heat transfer, and minimize the risk of cold seizures during operation.
Additional piston features include a machined smooth head that helps reflect combustion heat and reduce carbon buildup, supporting piston protection and consistent engine performance. The anodized dome improves heat resistance and durability, while strengthening the piston compared with non-anodized designs. The Namura Top End Kit fits 1988 through 1997 Kawasaki KLF220 Bayou models with the SRA configuration. Confirm the existing cylinder condition and required bore specification before installation to ensure proper fit and clearance.
