Correct.

When I first purchased the bike Jan 2014, the petcock was dripping. I took it apart and cleaned it. It's functioning perfectly now. Left the tank off the bike for 24 hours. Not a drip anywhere.

No. Can this be done at home? Or is it a service a shop provides?

There may be some corrosion behind those bolts that is hindering a good spark form the plugs. Of course this may not be the answer to your poor mileage.

I would have to take off the fairings to check. But the last time I looked at everything, I didn't notice anything with rust. Do you know where in the chasis the coil grounds are located on new gen bikes?

Would it be safe to assume my compression is good based on how it rides? It pulls from idle to redline really strong in all 6 gears. No hiccups anywhere.
The main jets are stock. They are clean as a whistle when I inspected them.

One of the vacuum lines from the tank is letting the emissions suck gasoline into that black box! yikes!

My bike is NOT Cali emissions. Only one line on the left side of the tank.

PM me if you need to....

Mike, thanks for all the suggestions! Much appreciated.
But the weird thing is.....I no longer smell gasoline in the crankcase. BUT BUT BUT, my oil level is rising.
See pictures here. I don't know anymore. I'm about to give up and sell the bike or trade it in or something. I just want to ride.....
