decelerating noise

[decoy]

riding around on the zx6, stock exhaust, its pretty quiet till you get the revs up. Coming down a hill today, doing some downshifting into corners, and the noise is really quite different from the engine. havn't heard it on any 250s, but on a few 600s that i know, even in the onboard zx6 videos i have. basically it's like a high pitched whine, kind of like a long chirpy noise, hard to explain! im pretty sure its a normal noise but just wandering what exactly it is.

Probably valve train whine??

Dunno what noise you're talking about. I can't hear my bike over the sound of the exhaust barking!

Could be the gearbox, it's full of straight cut gears

If it is the whine I think it is, then you got it in one Mick C. But I love the sound of straight cut gears... you should hear it both ways, but it is much louder on hard deceleration.

yeh i think you're right, definately louder on hard deceleration, i love it too but couldn't figure it out. thanks guys. I gotta hear your bike one day jason, what pipe do you have? i've gotta hear a couple in action before i decide what to get.

Me too, I have the loudest ZZR6 there is I reckon, I like the burble the zorsts makes when backing off the throttle.

Unless the temperature is down. Once the weather turns a bit crisp and the bike warms up, it's loud enough that Mark can't hear his bike over mine! And I was behind him....

Compared to what?....a space shuttle launch?
