About

About

+1mm forged stroker crankshaft for the CY460 (GP460) engine. Increases engine displacement by 1.4cc to a total of 47.1cc.  Increases exhaust port duration by 2.5° and transfer port duration by 5°.  If you are using this with a stock cylinder, you must use 2 standard thickness base gaskets.  When using with the ADA billet head kit, you can use the stroker dome that allows for a single base gasket and single standard copper head gasket.

We also sell a pre-modified and ported ESP top end compatible with this crankshaft, see part number cc585b listed in the "also purchased with this item" at the bottom of this page.
