so i'm thinking of doing a track day at Lakeside, and I read that they have noise limits around the track. How strict are they on the noise, and how should I go about testing my bike if it is too loud? Should I just download an iPhone app and test it that way? or does it need to be more scientific.. eg.. no more than xxdB at y distance at z revs. I don't want to book a day, show up, and then told my bike is too loud.
