It's a pretty easy job to remove the tank. There's just two bolts (at the back of the tank) securing it to the bike. Remove them and slide the tank back and up a bit to disengage from two rubber holders at the front. Prop up the tank at the back with a block of wood or something similar. Now just disengage a few wire connectors, a rubber breather hose, and the fuel line. The fuel line is the only part that's a bit ticklish. It's explained in the FSM, but essentially there's a clip you have to slide before the connector will disengage from the fuel rail. The key here is patience. Don't force it, because it would be easy to crack off that plastic connector with too much force. Note that the fuel line is self-sealing, so you don't have to worry about losing a lot of gas.

 

Excellent! , thanks Steve

 

Here you can see a picture clearing the "rise and use some block of wood to secure":

In this left side, near the front of tank you will find the breather rubber hose (simply pull it), and in the right side right over the spark area the two cable connectors for pump and level metering (they are linked to the frame by a tab, pull them up to release the block, and then open). The fuel line is right at the other side of those small colored cable connectors you can see near the wood.

Much better if you wait for the tank to be as empty as possible, for it to be light, and better if the bike is cold before dealing with the gas line (it is close the hot upper head of the cylinder).

I think I have some pictures of the other side, if so I will be posting

 

Thanks Jesus, I appreciate the tips.

 

Sounds just the same as on my Scrambler which is good to know as I think my next bike will be a Speedmaster. Awesome looking bikes. I had my tank off a few weeks ago and it was easy enough to do. I was careful reconnecting the fuel line as I have read some posts where guys have broken the tube on the injector rail and I didn't fancy doing that.
