Bring your 2-stroke cylinder back to service with the LA Sleeve KA5107 cylinder sleeve. This quality replacement liner is designed to give old cylinders new life when the original bore (alloy-chrome plated, Nikasil, or electrofused) is no longer usable. With precisely cut ports and a precision-ground outside diameter, it helps reduce the hassle during installation and supports accurate port match-up for a cleaner rebuild.
If you’re repairing damage, correcting excessive wear, or converting from a plated bore, this sleeve provides a dependable foundation for a fresh top-end. After installation, the cylinder must be bored to accept the sleeve, and the sleeve’s inside diameter must then be bored and honed to match the piston size—ensuring proper clearance and performance. Suitable for liquid-cooled engines.
Key features:
✅ Precision-cut ports for easier installation and port alignment
✅ Centerless-ground outside diameter for accurate fitment
✅ Quality resleeve solution that restores worn or damaged cylinders
Benefits of use:
🔹 Cost-effective rebuild option versus replacing the complete cylinder
