Where is all this heat coming from ?

• City stop and go traffic


• Engine idling


• Friction plate clutch


• The Transmission generates huge amounts of heat.


• The bike weighs 864 lbs wet. Lets add a rider and some gear and accessories. 1,100 lbs total


• The E.P.A. has new restrictions on emissions of how much motorcycles


• can put out. So to off set this, they run the bikes lean.


• Summer asphalt temperatures reaching up to to 155 degrees.


• The heads are placed under the gas tank eliminating the heat to escape


• Throttle bippers at the stop light…

Two Choices

To add additional cooling to the engine we basically have 2 choices.
Add a external fan system of some type. One of the problems is there is not a lot of room. And which direction will all that heat be directed

Add a oil cooling system to maintain the oil temperature. Maintain is the Key word here keep the oil temp in a range of heat. Don’t let it get hot in the first place.
