I had my first track day on my S1K today at Castle Coombe but ended up heading home as the bike failed the noise test. I have a standard bike with an Akro end can and no baffle as it didn't come with one. I warmed the bike up and put it in Rain mode as apparently that helps with the test (dont know why, was just told this by the noise gestapo). The noise level here is 105db half a metre from the bike at three quarters revs before the red line, so in this case 10,500 revs. The first time the bike was tested it failed at 110db. Someone lent me an Akro baffle but not from a S1K. It fitted but was not snug. This tested at 108db, so still a fail. There is a motorsport shop there so they offered to fit a DB killer and give that a try. Anyway that shook the retaining bolt loose and the db killer fell into the exhaust. Got that removed, had a fat boys breakfast and headed home ?120 worse off and really pissed off. I have ordered the bike specific db killer for the Akro from Calsport but I'm not even certain if that will reduce it enough to get below 105db. Its the 10,500 rev test which just makes it impossible.
Ten bikers failed this morning, including one guy on a brand new R1, standard exhaust etc and that recorded 117db.
