After 50 miles of tight, hilly, rocky , slow, fast Western Pa. riding, my 2000 E never came close to overheating for the first time ever. The solution? Took the whole cooling system off my 2001 S, including the fan, and put it on the E. Before you tell me about the jetting and the water wetter and all the other fixes,,,, I did them all, and so has my buddy on his E and he had trouble yesterday and I didn't. Suzuki should have done this from the factory, and hopefully they will in the future. Will have 2 E rads for sale soon. The two systems are VERY different.
