Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

You might want to drain that mix out of the fuel tank and replace it with actual fuel. BTW, those types of fuel preservatives don’t ignite like fuel and they lower the octane number of the fuel.

You’ve created an impressive cluster f**k there.

Update...
Battery on charge all night.
Changed the o ring around in the pump again as I found a photo with the o ring on top.
Starts and runs perfect.
Took for a ride, hesitancy still there but at least its going.
On a side note, battery seemed to drop down real quick after a few cranks, so I jumped it using the car and left the car revving, bike ran perfect.
No more exhaust stink and doesn't feel as hot gases out or exhaust pipes.
Now putting the iridium plugs in and try again.
Then airbox off and check hoses and visual on coils and HT's etc.
I wonder if the battery is on the way out or the alternator is not charging it.
On we go.....
Positive though.

Final update.
Thank you so very much all for your advices.
Bike is back to perfect.
No hesitation, redline eager as it used to be. Smooth.
Found a crack in cyl 1 vacuum hose, plus new plugs and a good blast out of the fuel system cleaner. Topped up with super and some octane booster.
That was stressful, but once again thanks to you all and thank god for the Forum.

Cheers,
Simon

Great job finding that vacuum leak!
When jumping a motorcycle don't run the car engine. Always leave the car engine off. Most all motorcycles use shunt regulation to regulate charging current. The car alternator output is capable of for much more current than the bike's shunt regulator can handle and will burn the shunt regulator out.

Again, great job on sticking it out and finding your issue/s. Wear your gear and ride safe!
