question about engine/exhaust sounds

So I have the 4-1 header with no baffle on the 1000 and the 900.
What gives the KZ engine's the lower/more raspy sound compared to other bikes? I have heard a few old Suzuki's, and I think they sound odd. Never heard any old Yamaha bikes, the old Honda Magna's sound pretty awesome.

You know, the crotch rockets are so high pitched. I know they are turning more R's, but why so high on the octave level? I heard one the other day, and it was ear piercing high.

I thing the thing I like the most about KZ's are the way they sound. Do the GPZ's and early ninja's sound the same way?

I've noticed the same thing and I wondered too. IMO it may have to do with the newer bikes having 4 valves as opposed to our 2 valves per cylinder? Plus they run at a much higher RPM than we do... :huh:

The engines on newer sport bikes have shorter strokes compared to KZ era engines. Unfortunately, they don't have crap on the bottom end, but wind em up to 8-9K rpm and they'll stand up.

Video where you can hear my unbaffled Kerker. Turn up the sound!!
