Yesterday I changed my primary fluid and on the tip of the plug there was a small pile of what looked like metal dust, it was real mushy, It's the second change in 2000 miles, I changed it because I seem to have a noisy transmission all of witch I am told (by dealer ) it is normal noise. The bike is a 2012 street glide, I have had 2 road kings and a ultra all of witch I don't remember having a pile of metal dust on the tip. Is this something to worry about or is it normal break in stuff.( This is the first bike I have done the fluids on before the 2 year warranty is up ).
