KIT INCLUDES:

• Cylinder - New, not remanufactured, cast aluminum nickel silicon carbide (NSC) electroplated big bore cylinder that appears just like an O.E. cylinder. NSC is a composite of a nickel and silicon carbide, providing an excellent wear resistant surface with oil retention capabilities. Cylinders are then diamond honed to the exact bore dimension and proper surface finish to ensure the proper ring seal and oil retention.
• Vertex Big Bore Piston - To handle the internal pressures of a four-stroke engine, Vertex's big bore four-stroke pistons are forged from the highest quality 2618 aluminum alloy for superior strength and durability. Vertex uses unique piston profiles and compression ratios, offered in A, B, C and D sizes, to maximize power and performance while reducing blow-by and oil consumption. Each Vertex piston is then hand matched to fit each Cylinder Works cylinder perfectly.
• Gasket Kits - These kits contain the necessary gaskets to rebuild your top end. Kits include head, base, exhaust gaskets, and O-rings necessary when removing the cylinder and head during routine maintenance.

PLEASE NOTE: Most kits can be assembled and used with perfectly with standard jetting/fuel injection. To achieve optimum performance, you can re-jet the carburetor or use a fuel-injection fuel management controller(sold separately). Contact our team for enquiries.
