2005 Yamaha FZ6

Hi everyone I am new to this forum and this is my first post..I got few questions I want to ask about my FZ6 hopefully someone can help me

First question is about the charging system..when I crank up the engine I get around 13.90 volts not at its best but should be enough to charge battery. now when high beam on it drops to about 12.50volts but if I rev it up it will give me about 13.80 volts so still charging battery.. The problem is when the fan kick with high beam the voltage will drop to about 12 volts..if I rev it up it will give me about 12.5 volts or less which is not enough to charge battery.. So I wonder what could be the problem..

Second it's about the gas mileage..I get very poor gas mileage on my bike.. something in the range of 30mpg or less I don't shift my gear at high rpm..mostly around 5-6k..I've change my air filter recently..here's a couple of pics from the spark plugs from the right side...Is that healthy spark plug? What else can I do to improve gas mileage?

Third and lastly I get white smoke from my exhaust..Now I know it's not condensation neither coolant burning..I can't track any loss in coolant.
