Abstract
A cylinder for a V-twin engine including a body with a first end having a surface configured to mate with a cylinder head, and a second end configured to mate with a crankcase. A sleeve is fixedly secured within the body to define a cylinder bore. The sleeve includes a first portion that extends from the first end of the body to the second end of the body. The first portion of the sleeve has a first wall thickness. The sleeve further includes a second portion that extends out of the second end of the body to be received within a crankcase bore. The second portion has a second wall thickness that is thinner than the first wall thickness. The sleeve is constructed from a chromoly steel alloy material, and the second wall thickness is less than 0.060 inch.
