A dry sump lubrication system for a four cycle engine is disclosed. The dry
sump lubrication system has at least two lubricant storage chambers. A
first lubricant storage chamber stores a first volume of lubricant. The
first lubricant storage chamber may be located in a lower part of the
crankcase. A second lubricant storage chamber is an oil tank and stores a
second volume of lubricant. The oil tank may be secured to the output end
of the crankcase. The first lubricant storage chamber is capable of
storing at least 30% of a total volume of lubricant within the dry sump
lubrication system.
