Restore Your Power with the LA Sleeve H5077 Cylinder Sleeve

A worn or scarred cylinder wall can lead to devastating compression loss and poor engine performance in your classic open-class 2-stroke. The LA Sleeve H5077 Cylinder Sleeve is the definitive OEM Replacement engineered to give your high-displacement engine a second life. At Moto-House MX, we specialize in providing the heavy-duty components required to keep legendary machines like the CR500R ripping on the track and trails.

Constructed from a high-grade Chrome-Moly alloy, this sleeve features an outside diameter that is precision centerless ground for a perfect interference fit. The ports are cut to exact factory dimensions to ensure seamless port match-up and ease of installation. This Heavy Duty sleeve provides a stable, long-lasting surface that stands up to the extreme heat and friction generated by a 491cc 2-stroke powerhouse.

Frequently Asked Questions

Q: Is this sleeve ready to run right out of the box?
A: No, the inside diameter is semi-finished. It must be bored and honed to the exact clearance required for your specific piston after it has been installed in the cylinder.

Q: Does this sleeve include the piston or gaskets?
A: This listing is for the cylinder sleeve only. We recommend purchasing a new top-end gasket kit and a matching piston kit to complete your rebuild.

Q: Can Moto-House MX help with the installation?
A: We provide the parts for your build, and cylinder resleeving services are available through the vendor if you do not have a local machine shop capable of the press-work.
