Re: Cut and paste thing.

I've got an HD and a Honda. The HD will knock in traffic and heat, while the Honda is happy. Main reason is that the Honda is liquid cooled, and oil-cooled. The HD is air-cooled. No movement = no air = really hot = pre-detonation = knock. The high octane is an attempt to keep the pre-detonation under control.
