PISTON KIT 87-06 YFZ350 65.50, NAMURA NA-40001-6 YAMAHA
PISTON KIT 87-06 YFZ350 65.50, NAMURA NA-40001-6. Piston Assembly - 65.50mm Bore - NA-40001-6. High-performance Namura pistons are engineered in the USA and manufactured in Taiwan using high-silicon content hypereutectic cast aluminum material for less heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing. Features machined, smooth piston crowns for reduced carbon buildup, increased horsepower, and fuel economy. Hard anodized crowns are 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures when combined with Teflon/Molybdenum coated skirts. MOS2 (Teflon/Molybdenum) coated skirts perform at the highest standards, reducing friction and heat for added power and longevity. Namura rings match the OEM design except as noted -B (.0004 in.) and -C (.0008 in.) fractional oversize.
