Electrical Issue/Engine Trouble
A few days ago I went to start the bike. It turned over a few times before making a clanking noise, and ultimately not starting. Then the battery was completely dead, and would not turn over at all. Yesterday, I took a voltage meter to it. The voltage on the battery was 10.xx. I put a charger on it, and the voltage increased to 13.xx. The bike started. I shut it off and it would not start again. Voltage read 12.xx.
Today, I replaced the regulator because a friend suggested that the regulator was a common problem. With the new regulator on the bike, and the bike not turned on, the voltage read 12.xx but would not turn over once again. Charged it up. Voltage quickly increased to 13.9. The bike turned over just fine. Shut off the bike, waited 10 seconds, voltage dropped to 12.xx, and bike wouldn't start again. Charged it up, started it just fine, and let it run 5-10 minutes. Bike makes a metalic clanking noise and hesitates while idling.
Also, with the key off and the charger on the battery, the battery voltage sits at 13.9, charger current equals 3amps. When the key is turned on, the voltage starts to drop below 12.5, and the charger current increases up to 6amps(charger current limit). Is it normal to draw 6amps with the key on?

The amp draw doesn't sound to out of spec I don't think. It sounds like you could have a bad battery, but the metalic clunking is what concerns me. However it's super hard to digo something you can't hear. Can you describe the noise you're hearing better? Almost makes me wonder if your CCT went bad or something.

sounds familliar (without hearing it) to what I went through...first your regulator frigged up your battery. then you bought a regulator (hopefully a good mosfet one) and still didn't replace the burnt battery....when reg goes it screws battery up! even though the battery may seem to be right it aint. Been there done that.

I would hope the battery isn't bad. It is brand new. Just replaced it at the beginning of this season. I also would hope it's not the CCT because I replaced it when I bought the bike at the beginning of last season.
It's really hard to explain the knocking noise. When I sit on the bike with it idling, it occasionally makes a clanking noise and I can feel a tap by my left thigh. With the clanking noise comes a slight hesitation in the engine production. For the entire year last year, the bike would do the same thing, but always at 3,500rpms, and always when it was cool out(never if it was warmer then 60-65).

lol I had a brand new battery in mine (costly) when my reg went bad, doesn't matter new or not...I had to buy another ... As for clanking Mine wasn't so much a clanking sound but the hesitation was there (possibly from not a good fire) but all was well after I changed reg and new battery

The CCT wouldn't make noise that's associated with a hesitation though. It could be coughing back in the carbs. It doing it more when cold further leads me to belive that. Try turning your pilot screws out a quarter turn and see if it gets better. If it gets better but doesnt' go completely away turn them out a little more until it goes completely away. You can also test this by pulling the choke out a little and see if it cures it.
Since I adjusted the needles down a half a position on my bike it's coughing in the carbs now so I need to adjust my fuel screws a little. Just haven't had a chance to try it yet. Runs perfect everywhere else but at very low throttle position and up to about 3K RPM I get that coughing and associated hesitation.

If they are set too loose the sudden declination caused by the misfire could cause the chains to slap which could cause the noise you are hearing.
