Cylinder Works turns up the horsepower with their big bore kits that look just like stock...but they’re not! All cylinders are nickel-silicon-carbide plated for a low friction surface, better heat dissipation and more durability. All kits come with everything, except the mechanic! Gaskets and seals, along with a Vertex piston, rings, wrist pin and circlips.
