My bike, a 998r has 20k plus on carbon sleeved termis and can pass a 105 db noise test.
They have never been repacked.
db killers on a bike are a last resort IMHO, sure they are a quick fix but I'd be looking elsewhere to quieten it down.
Have you got carbon or titanium termis? That could make a difference.
Have you got an open clutch?
There are a few other things that could help.
Pull the clutch in at the noise test, ease the revs up to those required by the tester, even a couple of hundred revs over those required can make a significant difference, was the bike fully warmed up?
It's pretty rare for a 748/996/998 to fail a noise test IMHO, I've seen a good few Ducatis with a 60mm system on that could pass a 105db test no probs. 105db is the ACU race limit in the UK IIRC
I'd have something to say if the test conditions were dodgy as well, did any other bikes fail that you might expect to pass?
Been Playing the noise test game for years in motorsport, so many things can affect a noise reading that are nothing to do with the bike being tested.
