Thanks to the advice in this thread I was able to solve my click on every rotation problem yesterday. I was thinking the worse, perhaps bottom bracket, loose crank arms, chain, but it did turn out to be a not tight enough pedal. I was sure it was the right side by unclipping one side at a time and doing one legged pedaling which revealed no click when the right foot unclipped.I pulled the right pedal which came off way too easily, cleaned and greased the contact points and voila problem solved.
