I've been tracking down the same thing on my Cannondale Synapse. It clicks at roughly the 5:30-6:00 position on the right side. If I put more pressure on the left pedal that gets rid of the click for a couple revolutions.
I have tried a new chain (needed one anyway), new bottom bracket (the plastic left side retainer was cracked), tightened the chainring bolts, tightened the cassette, and found one of the pedals needs replacing (can't rebuild.)
I have taken the bike for a short ride after each fix - will do the pedals today, and although the noise still pops up it is mostly gone, but I will wait until a good ride on a trail rather than our kidney busting local roads.
I've heard everything from these solutions to seat posts, headsets, and maybe sunspots. I would start by tightening up the above listed components, taking care to well grease everything.
Good luck!
