Yep that's what I said but it ain't good news, especially if you have an aftermarket exhaust and especially if this bill is passed in NH requiring all Motorcycles to comply to 95db or less measured at a 45 degree angle from rear at half the Motors
RPM.
That's where this gauge or meter comes in. When it was 1st proposed everyone pointed out that cruisers do not typically have a RPM guage, so hard to enforce. Well that's when DPS Technical Inc.
www.chemhelp.com stepped forward (And wouldn't you know it's a Ca. Co.) and said oh! We have one of those if your Dept has $40 we can sell you one!
It's called a sirometer and they use em in Formula one car racing. It measures an engine's RPM by vibration and it's very accurate. (Within 200 RPM) and it can't be tripped up by secondary shaft vibrations. You can even use it on your lawnmower.
But back on subject, it's another move towards states enforcing the noise law, This is to exhaust noise what Radar was/is to speeders. It starts in NH and if it passes there it won't be long other states jump on and next thing you know the aftermarket exhaust market changes and everyone will have to buy a stebel horn.
The Treysit Sirometer is MCN innovation of the month. They must not like loud pipes, and that thing has been around since 1950 so how much of an innovation is that anyways?
Ahhhhh might be a good tool for us though when setting the idle.

Seems like a lot of work.
I'm not as good as MS1700 on recognizing bikes by sound, but I do live near town on the corner of a busy street. I had to get new windows after living there for only a couple of years because of the "Rolling Thunder" Don't get me wrong, I think some bikes sound really good with a low "Powerful" rumble, same as my truck with dual exhausts and a slight rumble.
If you or a friend is being TOO loud, tell them it's NOT COOL!
