DannoXYZ, I think that you are correct on all points. I went outside a few minutes ago and with the bike supported I tried to get it to act up. I was only pedaling the bike by hand so the chain was able to stay on the big ring but I did notice that the chain was riding up on the teeth of the big ring.

I am thinking that a new chain will fix the problem. I am also going to look for some chain L oil. Where might I find this oil? Would something like STP oil treatment work as chain lube?

I also like hearing about rotating the chain rings forward by 2 bolt holes. I have been riding circular rings and I don't like the pulsing feeling of the biopace rings. I feel like I am going up hill in a series of lunges. It is just not a smooth motion or application of power. I also find that I bounce more when I try to spin the biopace rings as opposed to spinning the round rings.

It looks like it is going to rain in a few minutes so instead of riding I may just go ahead and replace the chain.
