If it was me,I would go for a nice day ride to use up some of that fuel before lifting the tank. I have lifed the tank with fuel in it with no problems.
To avoid removing the inner cowling, I removed the two front bolts and then the rear bolt, slid the tank back until it cleard the inner fairings, re-inserted the rear bolt and then used bungees from the two front bolt mounts back to the handrails on the seat.
Check to make sure none of the fuel lines come loose and be sure to avoid pinching them when you put the tank back down.
I just put a file folder clip on the vent hoses before I lift it up all the way. Then, I'll only get a tiny little dribble out after I'm done and take them back off.
