A thought on the quieting effect of Dead Animals
Could it be that Dino has the ability to dull or absorb sound differently than Syn. Thus quieting a "normal", however annoying characteristic of the engine design. Think about it, the design of the engine and it's parts generate sound as well as power. Different designs generate different sounds, Harley's are different than Kawi's. Newer Kawi's are different than in the 80's.
Could be that the different raw material just changes the sound. And probably there was never a "mechanical risk" to what was causing the sound. I just was not appreciated.
