Called Bill at Wallingford this morning, and told him the creaking/twanging/snapping in my B67 wasn't getting better. He told me to take the seat off the bike and which parts to wiggle to see if I could isolate the noise.

After I found the offending bit, I called him back. He told me where to put oil or grease (grease would be better). I dripped some T-9 in there (I have no grease). I also backed off on some of the tension. (since increasing the tension wasn't helping)

Preliminary results are that the minor "surgery" was successful! If I wiggled the shackle and bolt, no noise. Put the saddle back on the bike and sat on it. No noise. Rocked on it, no noise. Put my hands on each side and torqued over the springs, NO NOISE.

I'll try riding it tonight after work.

Bill is very cool.
