Noise restrictions

(1/3) > >>

jolly green thumper:
Would anyone know the db level for a stock 2003 KX500. In order to ride on Gov't land and participate in some Hare Scrambles in Ontario bike cannot be any louder than 94db. Almost certian stock 500 exceeds the limit. Does anyone know of any combination of stock/aftermarket pipe/muffler that would pass these noise restrictions. Riding areas in Ontario are closing due to noise, erosion, and illegal dumping issues. Dirt riders are being blamed  for all of  these.  After an area is closed in order to preserve nature, developers pull in, cut the trees down and pave over the entire area. Hope for all this is not a common problem where you ride.

There is a snorkel type silencer in the latest DirtRider mag that is a little ugly but is supposed to work great.My Turbine core sparky from FMF did nothing for the noise.

I got hammered in Minnesota for my K5 being to loud.  The standard is under 99 dB(A) when conducting the stationary noise test (SAE standardized J1287 test). The lady that did the test said I could not ride because I was well over the limit.  She didn't say how much and I did not think to ask.  I run an FMF Gnarly with FMF Power Core.  Most likley I need to repack it.  I gave her the wah wah story.  I told her I drove 1000 miles for a wedding and brought my bike just to ride at the Iron Range.  http://www.dnr.state.mn.us/ohv/iron_range/index.html
Since I was just a 1 day rider she said I could ride because it was a weekday and only about 8 people were riding that day.  That weekend they were going to winter hours, weekends only.  If you are under 18 you have to have a rider safety course and be certified (card in hand).  I'm so glad she let me ride because I had a blast.  I have never heard of or seen anyone get sound checked in Oklahoma.
