My T1 had a lot of noise stock aswell. It was pretty much the first thing I noticed. I thought to myself this seems pretty noisy straight from the factory. I don't think the chainline was perfect to begin with. I've since changed the chainline (to make it actually worse than stock) and I have the exact same noise. This is all with half decent components Stronglite chainring and Dura ace rear cog all 1/8".
