How to make my Shovelhead "cackle" when I pull the clutch in??
What makes the engine do this? Is it stiffer valve springs? Larger valves? Higher than stock compression? The bike currently has a Andrews A/B grind cam and is bored .30 Over stock, engine is a 1976. My dad has a 93 ci sidewinder Shovelhead I believe and it sounds like a fire breathing dragon when he pulls in the clutch. Lets face it Harleys are about appearance and show, when I finish building my bike I want it to make this sound. Someone please tell me how. Thank you in advance for any and all advice!

Its running 2" drag pipes now and doesn't do it unless I run the RPMs up high as hell, will switching to 1-3/4 make that much difference? My dads shovel cracks when you pull the clutch in even if your only at 1k or at any speed in any gear, I think there is more going on than just pipes. His bike also hauls A$$ and he is running 2" straight pipes as well so what's the difference here?

Like in that video, you might want to be following your bike while someone else rides it, and see how it sounds from there.
Bikes don't sound the same from every perspective.
My old ironhead sportster chop made that noise all day long, .030 over pistons, 1 3/4 drag pipes, slash cut.
