Does that mean i have to buy the coffee??
Let me get this straight.
-You're a resident of Belfountain
-Your bike may or may not pass the Db test (and you find that humourous)
-Your other bike registers 123 Db
-Your first post here is to tell us to stay out of Belfountain
That's a hell of a lot of win for one thread.
The SAE J2825 standard, recommends a decibel limit of 92 dBA at idle for all machines. RPM test of 100 dBA @ 5000RPM for three- or four-cylinder machines, and 96 dBA @ 2000 RPM for bikes with fewer than three or more than four cylinders. The meter is suppose to be 20 inches from the exhaust outlet at a horizontal angel of 45 degrees from the pipe.
Consider most tracks limit the noise to between 98 and 110 dBA depending on the track this does not sound too unreasonable for street machines. I think stock exhausts are suppose to be around 88 dBA (as in OME pipes).

Not positive on the track limits Rob. Pretty sure Calabogie is 98 dBA, the others I'm just trying to remember lol.

They just passed this law in edmonton and i dont think they got more then 60 or 70 bikes in the first few months, not even enough to pay for their decible meters lol.
My buddies 1098 with termi's comes in right at 96 (twins only have to rev to 2000 rpms). Very few bikes fail this even lots with full systems, the biggest failure rate is guys on cruisers with straight pipes, and honestly those are annoying as hell and should be ticketed.
The bigger issue is it gives them an excuse to hassle motorcyclists. They are pulling you in for noise testing but no doubt will also use it as a chance to do a paper check and ticket you for anything else they can come up with (improper plate mounting, blah blah blah).

Driving a cage is to have sanity forced upon you.
- No I'm not a resident of Belfountian, I live in Caledon.
- I'm for it as long as my passes
- Yes you did read that correctly
- I never said to stay out of Belfountian, you must have just assumed that, ride through as much as you want, I was just letting people know what to expect when they do visit that charming little town in the next few weeks.
- Lot of win for one thread, maybe I should buy a lotto ticket..lmao

I'll be working the store with Ray.

F Caledon!
I will gladly avoid that municipality while I ride my bike AND drive my car.
I will also gladly not patronize businesses in that area if they believe that motorcyclists are a nuisance.
I have no intention of having my bike's exhaust scrutinized by some OPP flunkie who should be spending his/her time engaged in more substantial matters such as locating and arresting murderers, armed robbers, drug traffickers, child pornographers and similar classes of criminals.
F them!!!!!!!
There was a LONG thread about this already, earlier this year.
I've had all of my bikes tested. 3 out of 4 have aftermarket exhausts. ALL of them are in compliance. One of the bikes with an aftermarket exhaust measured lower sound level than the one with a stock muffler.
If you have a stock bike, you will not have a problem with this. If your bike has a *decent* aftermarket exhaust system with a decent muffler, and the packing has not blown out, you will probably not have a problem. Only if you have an unmuffled exhaust (cruisers) or a grossly undersized or inadequate aftermarket muffler (D&D and LOR "mufflers" come to mind) or you have no packing left in the muffler or have cut the muffler shorter in the interest of style, are you likely to have a problem. If you've intentionally bought the loudest exhaust you could find, or if it's noticeably louder than all of your friends bikes, it's probably going to be an issue.
It is NOT a requirement of this standard, that the bike be absolutely bone stock. Repeat, that is NOT the requirement. It can be modded all to heck, and as long as it passes the test, it passes. And since the test procedure is publicly available, and it is an objective test (as opposed to the HTA, which leaves it to the discretion of the officer!) you can find out *for yourself* if your bike has a problem. There is an app for an iPhone that turns it into a decibel meter. It's not considered a calibrated test sufficient for evidence in court ... but it seems to be good enough for you to find out whether you have a problem or not.
May not be court approved, but definitely a good indicator.
This ones free - and has a user entered "offset" which allows you to calibrate the app to virtually perfect - just need a calibrated SPL meter in order to set the offset.
this particular app is called "SPL meter"

This test should apply to all vehicles, not just motorcycles. I fully support it, though I believe the db criteria is too lax. The vast majority of all bikes on the road will pass. I'm not from Belfontain, but sympathize with residents. Some of the cruisers that run through there are way "over the top" loud. If they stay away, so much the better for residents and other motorcyclists.
I also hope this standard gets adopted widely throughout Ontario.
Thanks for bringing this topic to our attention.
Let's have a civil discussion.
