Restore your 2-stroke cylinder instead of replacing it. The LA SLEEVE KA5251 cylinder sleeve is a quality replacement liner designed to give worn or damaged cylinders new life. It’s a smart solution when the original cylinder bore is alloy-chrome plated, Nikasil, or electrofused—allowing you to machine the cylinder to accept a new sleeve and return to dependable performance.
Built with a precision centerless-ground outside diameter and accurately cut ports, this sleeve helps simplify installation and improves port match-up during a resleeve. After installation, the inside diameter is designed to be bored and honed to match the piston size for correct clearance and long-lasting reliability.
Key features:
✅ Ports cut to precision dimensions and shapes for easier installation and port match-up
✅ Outside diameter precision centerless ground for consistent fitment
✅ Quality replacement sleeve to renew worn cylinders (resleeving service available through vendor)
Benefits of use:
🔹 Cost-effective way to repair and reuse a cylinder instead of buying a complete replacement
🔹 Helps restore compression and engine performance after cylinder damage or wear
