Ecu does fuel and ign curves. As in advance or retard, nothing to do with staggering of the cam timing.

Agreed! But, the articles I've seen specifically mention valve timing (not ignition timing) which would suggest a change in lift or duration. Speculating here, but mild cam lope in an inline motorcycle engine probably comes across as an amplified buzz at higher RPMs instead of low RPM burble.

Not saying it's true but there does seem to be some logic to how this "rumor" may have started....
