Here's an idea: be a good person and quiet your fkin bike down anyway, regardless of the law. IMO if you're asking this question, and your bike is louder at idle than your dad's Harley revving, it's too loud. Am I gonna have to end my conversation and plug my ears if you drive by my house? Then it's too loud. It's not about you, and nobody thinks your bike is cool when it's piercing their ear-drums.
Cruisers with straight pipes deserve to be crushed for reals. :violent2:
If I'm cranking it, and you're on your front porch 5m from the street, you might have to speak up, yes. When I'm near houses, I try to keep it down in 'putter' mode, and at idle I find I can still talk normally just fine. I've yet to do a real analytical side-by-side with the Harley, so I may be wrong on that. Bottom line though, is that it's not ear-splitting unless I make it ear splitting.
My two cents, for whatever it's worth - if you've modified your exhaust system from stock, you run an increased risk of being charged with an excessive noise offence. That's the easy answer. Most municipalities haven't adopted a DB standard yet, but there are a few in the GTA and I think most are mentioned in this post above.
Of course if you are being overly exuberant you will attract 'attention' to yourself, and you will roll the dice with whatever officer is nearby.
Wow, I actually really appreciate you joining up here, you can be a huge help, and an ambassador here, assuming your name is correct

I have a feeling that I can pass the 2825 test, which as you know is the test adopted in Caledon.
An opportunity to ask a cop here: Is there any station I could get tested at, and *not* get fined if I'm over? I'm an honest citizen, and I want to see if I can pass, without having to buy the equipment ($100+) or risk fines. If I'm over, I'll get quiet baffles, plain and simple, but I think the idea of an olive branch (amnesty for the sake of awareness) is better than simple punishment.
