Full Campy Chorus with carbon cranks. The bottom bracket area is emitting a quiet tick-tick-tick - obviously only when pedaling. Before I lose the bike for two days by taking it to the LBS does anyone have any suggestions? Happens in most gears, and seems to be getting worse. Also seems to be more prevalent at lower intensities, although maybe that's just because the sound of the wind is increased when I go faster.

many sources

Could be as simple as the front derailleur cable ticking against the crank each time it passes. Does it do it when you are standing up? Does it do it when you ride no-hands? IME, the most common problem is inadequate grease or torque on the BB threads, but there are LOTS of other sources.

It is fairly common to have clicking noises, but ticks and clicks are very hard to eliminate sometimes. What seems like it is tied to the pedals may be coming from the seat post, etc. Sometimes things like temperature and humidity can affect noises as well. Clicks tied to your pedaling can come from the BB (grease all threads in contact with the frame and BB, and torque it to the recommended settings, which can be quite high), crank bolts (grease threads and washers), the chain ring bolts (take them all out and grease the threads, the faces where they contact the CRs, and the CRs where they contact the crank spider arms), the pedals (grease the threads, get some wax etc. on the cleats, grease the bolts into your shoes, squirt some lube into the guts of the pedal machinery if possible), the chain (clean and lube), shoes/cleats (loose cleat nut rattling around in the shoe sole, shoe/cleat interface, cleat bolts, cleats touching pedals), your seat post and saddle (grease the post, seat post bolts, saddle rails, and add some oil to where the rails go into the saddle body), your bars and stem (grease the stem, stem bolts at both ends, h'bar bolt if quill stem, and h'bar where it goes through the stem, steerer tube spacers if threadless), replaceable derailleur hangers (remove, clean, grease all parts and threads, reassemble), the nuts on threaded Presta valve stems (throw the nut away), reed switches in computer pickups, the front derailleur cable hitting the crank, and your wheels (check for spoke tension, particularly on the rear non drive side, put a drop of lube where each pair of spokes cross, grease/tighten QRs, tighten cassette lock ring, check for loose metal bits or spoke nipples in the body of the rim). Needless to say, you want to try these things in what seems like the most likely place the noise is coming from, but there are plenty of stories about "I was sure the noise was in the handlebars but it went away when I tightened up the spokes in the rear wheel," so keep trying different things until you have success.

I lived with a tick for over two years before I figured out what it was, the pedals, try removing them, cleaning the threads and putting grease on the before you put them back on, be carefull not to get any on the carbon though, some greases can reak havoc on the epoxy they use in carbon.
