I have Muzzy race pipe on my Kawasaki ZRX 1100. If pulled over, I would let them put the sensor on the back of my pipe while at idle (very quiet here). I would not give them permission to operate my vehicle. I presume they would instruct me to give the bike gas. I would rev it up to 3,500 RPMs and say that is all I take bike up. Past that and the pipe wakes up…
Just because it is capable of being over the limit does not mean you have, are, or will violate the law. See the issue?
