How do you get your bike noise tested? These sound meters can be pretty expensive to use only once or twice. I have a two stroke CR250 and want to use it on the public trails. There is a 96db restriction and I have no idea how loud my bike. One thing for sure its alot quieter then a comparable 4 stroke! That being said I know a bit about power spectrum and noise is measured at certain frequencies which is more sensitive to the pitch made by a two stroke.
