After many years of riding H.D.s as well as Nortons, Triumphs,and BMW's, I have never had a problem with overheating. Admittedly, I don't live in the South or Southwest, nor do I do much urban driving. Still, I just wonder if this is really necessary; just saying. I also understand that the S&S motors are tuned very lean to pass California standards, hence the discolored pipes after 25 miles. Lean and air-cooled, not a good combination. Any opinions?
I agree, I believe they're tuned lean and run hot for emissions. Now, once out of warranty, I think some special tuning and mapping would set things right.
