Twist your right wrist rearwards until you hear the rev limiter start working......then vigorously and rapidly release your left had from around the clutch lever as fast as humanly possible.
I'm not certain.....but I have reason to believe the front tire may lift off.....
***NOTE****
If you preload the driveline just a tiny bit......you want to be able to stop forward progress with your feet.....it will help with all of that banging and clanging that's making you think the drive shaft is about to wrap itself in two.

odd...I'm looking to sell my FZ1 and get a 2016 FJR because, among other things, it power lifts the front wheel WAY too easy in the first 2 gears and sometimes in 3rd if I don't have much gas on board.....when you have the wick at full twist on a curved onramp and it starts to power wheelie and walk towards the gravel line, the pucker factor will redline and you will wish you were still on the FJR....
Just some random thoughts and MHO....
