Funny noises troubling you too? It could be anything in the drive train 
really. With your chain off, check the crank for looseness (side-to-side) as 
well as binding. Same for the idler--if it's been binding, you may see 
uneven wear in the groove. Your pedals may also be the culprit. Make sure 
your rear wheel isn't chafing a loose object. Set it in a stand or trainer, 
if you have one. Shift into a wide range of gearing (with pedal pressure to 
simulate drive load). Chains often rub against accessories, baggage or 
shift/brake cables. Check your chain for wear (esp considering how dry it 
was prior to your latest lube). Each link measures 1/2". Overall chain 
stretch shouldn't exceed 1/8" for each foot of chain. If it's worn out, then 
you'll have to inspect cassette and chainwheel for the same type of wear.

I hope a little of this helps, George.
