Recently I've been hopping on the bike and trying to fire with no avail. One crank and that's it. I recently replaced the battery and thought that would do the trick, but clearly its not that, cause I've had to charge it up twice now. What could possibly be draining it? Where do I start? This is super annoying.

Other that that, it runs great.

Does your 2010 have the upgraded Regulator/Rectifier (warranty recall)? If not it may be the cause of the charging problem. You can connect a voltage meter to the battery with the engine running it should read close to 14v and a fully charged battery with engine off should read over 12v. Make sure the ignition key is not in the 'park' position.
