The cylinder members are modular components, which may be pre-assembled with components of the valve train as packaged units before the cylinder members are attached to the crankcase. Each cylinder member rotatably supports a cam gear (156) which extends into the crankcase for driving engagement with the crankshaft (58). The cylinder members may be configured for either side valve-type (\"L-head\"), or overhead valve-type (\"OHV\") engines, and the cylinder members may also be used in single cylinder engines.
