Top end rebuild kit for 2014-21 KX85. Cylinder is a properly Replated OEM Kawasaki - stock bore size, with a standard (A-size) piston. *Due to the fact that a large number of our customers do not return their cores (which depletes our inventory and cannot be re-plated for the next customer), we require you to Send Your Core to us before we release your order. Place your order, we pull it and hold it. Once your core arrives we ship the order. Cores cannot be iron sleeved or ported. We will not exchange a stock perfect cylinder for a iron or ported cylinder. Now if you have a iron or ported cylinder we can still bore or plate those, but we will not exchange for our freshly plated stock cylinder. Please remove to ALL fittings including studs, power valves, etc. as our cylinders are shipped completely bare. Please avoid any damage to gasket surfaces when removing these items as it could result in a repair fee.* INCLUDED: - PRO-X Piston or Premium Wossner piston optional at checkout - Rings - Wrist Pin - Wrist pin bearing - Circlips - Top End Gasket Kit - Re-plated Dimensions and plating are within factory Kawasaki specs.
