One of the Yamaha
Banshee's biggest impediments to high power is heat! The standard radiator is
only a 2 row, 11mm thick core design that is barely sufficient for a stock engine.
Put high performance pipes and 
engine
work on your bike and the radiator's capacity is quickly overwhelmed. Nothing
kills power (and engines) like heat!
Some companies try to tell you that by changing to an expensive cylinder head that carries more water will cool your engine.......but how can it? More water volume does not cool anything, it just ads weight! Imagine you connected your water cooling system to a 55 gallon drum of water. Besides taking forever to heat up to operating temperature, there really is no added cooling happening now is there?? The same volume of water must trickle through the stock radiator, where the water transfers its heat to the aluminum fins and is carried off by the air passing through the radiator. So, big capacity heads are a fallacy, besides, they usually are higher compression, and PRODUCE more heat!
As you know, there is only ONE thing on a Banshee that conducts the heat away from the engine..... the WATER! and there is only ONE thing that conducts the heat out of the water..... the RADIATOR!
The solution? Greater radiator capacity!
NEW!
for 2000, We have a beautifully hand made, all aluminum, 40 mm thick, single
core design, Super Cooler Radiator, that will drop right in to the standard
radiator mounts, and connect right up with all the standard hoses, and provide
a massive increase in surface area with which the hot engine water can dissipate
its heat. An increase of several hundred percent of cooling surface area over
the stock radiator is afforded you with this simple drop in installation. You
might even have to tape some of it over in winter!
Best power comes with controlled temperatures!
Take control now with the Super Cooler!
