Hello, I have to tell you what happened to me. At the end of summer 2005 I got into a police check with my YZF 750 R everything org. except exhaust! (my opinion is not too loud). Before me was one with a Ducati which they also stopped. Then about 4 policemen just came to me driving license/vehicle license please. Two immediately looked at the motorcycle, one of which said she was in a good condition and the other immediately to the exhaust, which is not “ORGINAL”. The exhaust was of course without papers from Phoenix Remus, one saw only with exact look that the not quite in order. They immediately unpacked their db measuring device and measured it. approx.50 cm distance behind the exhaust then let the machine run at approx. 5000 rpm. According to my papers 91 db, after measurement 102 db. They then mossed around because the allegedly louder than an airplane and bla,bla. They said if I in Frankfurt with the engine The police then said that I had to show the bike within a week. Then another ad came up to me and points. After a couple of days I went to Limburg to the police with org. Pott.The police officer didn’t even look if it was right just signed and finished. So then 2 weeks later came the Schrieb: Bla,Bla,Bla 75 Euro Straff and the Hammer 3 PUNKTE in Flensburg. I thought to myself. Question to you: In my vehicle license there is 91 db of standing noise and they measured at 5000 rpm and then said that they were 11db too high. 5000 U/min. isn’t there a standing noise??? Can you help me there much further.Because probably already too late is almost statute of limitations. Gruss black-sx
