My cold starts aren't that cold, I live in Florida. When I fire up the bike for the first time in a couple hours, it makes a clicking sound on idle that goes away after about 30 seconds or so. It runs great, I always warm it up and take it slow at first, etc. I don't know if I'm just being paranoid but I noticed it after my oil change. Stood the bike up and checked the oil level, its right at the halfway mark. Used the correct viscosity, correct filter, no leaks, etc. So... Paranoia?
