An engine is disclosed having a water cooling system allowing efficient cooling of the exhaust valves to prevent temperature gradients from building in the engine. Water is therefore pumped through the engine though first and second water cooling cores which discharge through the head. A water manifold is positioned over the discharge opening and includes couplings for the radiator supply, radiator return, water pump supply, oil cooler supply and oil cooler return. The engine has separate chambers to isolate the pistons and cylinders, and reed valves cover the chambers and allow the blow-by gases and oil to enter the oil pan during the power stroke of the engine cycle.

Engine

A vehicle may include a CVT unit or a power source which requires ambient air. An air inlet for an air intake system coupled to the CVT unit or the power source which requires ambient air may be provided in a side of a cargo carrying portion of the vehicle. The vehicle may include a rear radius arm suspension.

A brake () having application for a linear or rotational motion device includes a housing () in which a first piston (), a wedge () and a second piston () cooperate to engage a friction facing () through a plurality of rollers (). The three part piston assembly () allows a braking action and prevents torsional forces that are non-axial to the axis of the first piston () and second piston (). The pistons () are biased by compression springs () and may be actuated by a fluid.
