Is pulse & bleed a valid technique?

[The Toecutter]

I've tried 'pulse and bleed' with the piece of **** Suzuki I drive. Didn't work well in my case. Better kept at a constant speed.

There's the Harley riders who feel so inadequate and starved for attention they do everything in their power to maximize their noise output, all in a juvenile effort to get noticed: "PLATPLATPLATPLATPLATPLATPLATPLATPLATPLATPLATPLATP LAT."

While of no intention of my own, that is pretty much what the Triumph sounded like. Only louder and even more obnoxious. Then when you step on the gas...
"R-I-I-I-I-I-I-I-I-I-NNNNNNNN". Like a Harley getting *** raped by a Formula race car... Had no problem setting off alarms on parked cars.
