[QUOTE="Black Flash, post: 32442, member: 433"] Hi Vibrac, the MOT tester we went to see races a Seeley G50 himself in German Historic Racing and is just restoring a Metisse Commando for a roadbike. He really is a bike nut and quite helpful, but when I started up my Comet, he turned pale and said: this thing is more noisy than my G50 racer and as much as I love old bikes you are not going to ride this one on the road. By German law you measure the noise over hard ground (tarmac) 1 meter behind and 45 degress sideways to the exhaust opening at exhaust height. you then have to rev the engine to half the rpm you have max Power (i.e. 3200 rpm) and snap close the throttle. with the resulting bang on snap shutting the meter went to : ERR . Nuff said. I had to trailer my bike home and am trying to calm the exhaust down just enough to please the guy. In one respect it was real fun to show off, but then this grin cost me 60 € and I have to come and pay again. Bernd [/QUOTE]
