This Taida Cylinder Head 61mm 2V fits the Taida Cylinder 58.5mm 2V or 61mm 2V Cylinder. When pairing with Taida Cylinder 58.5mm 2V and Taida Crankshaft 57.8mm Stroker will produce 155cc engine displacement. In order to get 171cc engine displacement, you'll need to pair with Taida Cylinder 61mm 2V and Taida Crankshaft 57.8mm Stroker, to produce 171cc engine displacement. To increase further performance, we suggest adding a performance Taida Camshaft T-300.
