Taken from another post I made a few months ago. I thought it might come in handy for anyone looking to remove the tank...
Take off both the side covers and lower fairings.
Let's Get Nekkid!!!
This is for a 49 state bike. If you have a cali model there may be more steps/hoses than this to remove the tank.
1. Take seat off. One Allen on each side of the seat. There is a washer inside each mounting hole of the seat. Don't lose them.
2. remove 2 10mm bolts at the rear of the tank along with the bracket they hold down.
3. prop up the rear of the tank with a small piece of 2x4 so you can gain access under the tank.
4. unplug the gray vent hose from front left side of the tank.
5. under the tank, undo the fuel sender connector.
6. under the tank, remove a vacuum hose that runs to the fuel petcock.
7. under the tank, make sure the fuel tap is in the "on" position and remove the hose from the fuel petcock. The valve is vacuum operated and with no vacuum, no fuel will pour out of the tank as long as it is in the "on" position. Do not leave it in the prime position as fuel will
run out... ask me how I know.
At this point you should be able to lift the tank off by pulling the rear of the tank up and towards the rear of the bike. Make sure the black console plastic that wraps around the upper tank fairing mounting holes are free.
When you put the tank down, make sure you place it on a blanket or cloth to avoid scratching it and don't let it rest on the petcock. I use a small 2x4 under that area ahead of the petcock to make sure the tank isn't resting on it.
No need to drain the tank before removal, but if you do start with a full tank, it is quite heavy compared to it empty. Again, ask me how I know.
