    • A v-twin type engine (20) according to the present invention comprises an engine (20) comprising a single cylinder block (22) and a crankcase (23). The cylinder block (22) is formed with two cylinders (26, 28) and a lower connection region (24) adapted to be attachable to the crankcase (23) of the engine (20). Disposed at the top of each cylinder (26, 28) there is a cylinder head (30, 32). The lower connecting region (24) is formed with a flange (34) that extends around the lower perimeter of the cylinder block (22). The flange (34) is received by an opening (36) formed in the crankcase (23). It will be appreciated that the flange (34) will follow the contours of the opening (36) and the crankcase (23). The flange (34) forms a seal with the crankcase (23).
