Pedal click, drive side

I’ve had a nagging click in the right drive-side pedal for quite some time now.  Using advice from Bicycle Tutor, I looked at the more obvious places for the click.  I took the pedal off and regreased the threads.  I fixed two stuck links in my chain.  I also tightened the crank arm bolt just a bit.  Unfortunately, none of these fixed the issue causing the noise.  The noise occurred on the down stroke, when my right foot was at about the 2 o’clock location in the pedal revolution.  The noise was more obvious when riding my trainer indoors, as there was no wind or road resisitance to muffle sound.  I thought I was looking at a bottom bracket overhaul.  However, with the recent acquisition and installation of a Brooks B17 saddle, the noise seems to have disappeared.  I should have paid more careful attention and noted that the noise did not occur when I was out of the saddle.  For now, my drivetrain noises have disappeared, and the mystery noise has been attributed to the old worn-out seat.  Now all I have to be worried about is trying to break the Brooks in a bit.  Only another 490 miles or so until it feels just right.
