I was done with my zx12r in 2002 while running it in at Kinglake Victoria.
The Police were waving over all sportbikes into a parking bay where the EPA were set up testing noise levels. I was not about to rev a new motor to the rquired revs so after a heated disscusion I was tested at 3000rpm and came in at 100.3 db. All I had to do was comply with a notice within 14days and after putting my original muffler back on for testing and $25 for the test I was back in the clear. This blitz was the result of boyracers in their T-shirts being d@#kheads in the area. But the part that really pissed me off was that they were waving on every Harley/lookalike cruiser. Talk about discrimination. Been riding the spurs and ocean roads since and have not had any attention as a result of loud pipes.
