Abstract

A thermostat housing assembly for a motorcycle engine includes a body portion defining a cavity and an inlet port communicating with the cavity. The inlet port is configured to be directly connected to a water jacket outlet. The thermostat housing assembly further includes a return port communicating with the cavity and configured to be coupled to a return line. A thermally-responsive valve in the cavity selectively prevents and allows communication between the cavity and the return port. Preferably, the thermostat housing assembly further includes a second inlet port communicating with the cavity and configured to be directly connected to a second water jacket outlet. Further preferably, the first and second inlet ports are substantially parallel to each other and the first inlet port is longer than the second inlet port. Each inlet port includes a connector for connecting the inlet port to a water jacket outlet.
