Understandable.
Why? Is it because they'd be afraid that a little 35 year old 400cc Yamaha would out-perform them?
No, it was that ring-ding-ding-ding-ring-ring-ring exhaust note.....
Actually, I doubt it. One little two stroke in with ten or more straight pipe Harleys wouldn't even be heard. I'd say they were afraid of the little bee's sting!
"Now about that Kaw - didn't it have a certain growl - along with the ring-ding-ring? When you opened them up - sounded like a four-barreled carb kicking in...."
High performance two strokes have quite a bit of intake noise. I know that when I open up the Yamahas, I don't hear the exhaust. The rider hears mostly intake honk.
Different expansion chambers also make different sounds. I have a set of DG chambers on the RD400. They have a real nice rumble to them at lower rpms but screech when spun up to 10000 rpm. The RD350 has higher performance race tuned chambers that snap, crackle and pop at low rpms but really wail when on the pipe.
