Cylinder Works four stroke cylinders are ready to install, eliminating the
hassle of sending out your cylinder for replating or boring and are
competitively pieced compared to typical replating costs. Cylinder Works
cylinders look virtually identical to the OEM. This makes the YFZ a 478cc monster!

22-7480 (MSRP $79.99)
Also included is a complete gasket kit. The Big Bore Kit comes with a top end kit and then we send complete Cometic Gasket kit. You'll have an extra top end gasket for a stock YFZ because nobody sells just bottom end gasket kits. That being said we do not factor the extra top end gasket kit into the cost.
