Exhaust 'fluttering'?

[200 Alex]

On over run from about 3700rpm down to about 1700 my yozza seems to be making a fluttering sound? Could this be the exhaust blowing somewhere? Or is it just excess fuel in the exhuast?

Do they all do this? Its only 2 days old so could it still be bedding in and that is the cause?

cheers

Could be that. I'll get that checked and sealed. And yes, but I thought there was no difference? Correct me if im wrong

Thinking about it, we did put a pretty rusty C clamp on that join.

Got a new one on its way, get it on the ramp and fit it today. see how it goes.

Whatever its called, it sounds fapping awesome.
