Since I can't kick the clutch off on my bike, I have to engine brake down to 15mph before I can start coasting.
I just shut the kill switch off, open the throttle wide, (I removed the snorkel tube from my airbox), and it sounds like a small diesel hitting the jake-brake. It also decelerates rather rapidly, so I see a lot of cars dipping their front ends behind me.
Sure, one of these days some inattentive non-driver is going to slam into my Ass, but it'll be their fault anyway for tailgating.
