Pardon the ignorance of this basic question, but I don't want to risk overlooking something important. I have a '79 GS750E, and would like to know the basic steps for removing the tank.....obviously there's a bolt in the back that needs to come off, but how do you deal with the fuel lines, etc.

Simply disconnect everything. There should be bolts to hold the tank on. Fuel and vacuum lines on the petcock and a couple electrical (bullet) connections for the fuel gauge. Easy peasy.

Unbolt the tank at the back and lift the rear so you can undo the fuel and vac lines. Then slide it off the mount and lift the front to get the sending unit unplugged...lift off the bike.Last edited by chuck hahn; 04-30-2014, 10:58 AM.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.Comment

There's no sending unit, as there's no gas gauge. Lift the back, undo the hoses as chuck says, grab the front of the tank under the gas cap cover. Lift the tank up and back while wiggling it a bit to get it off the hocky pucks.
DO NOT lift the tank by that cover, it may pop open and if it does you will drop the tank.Comment

sometimes a good idea to put a rag under it to catch any gas drips.Comment

It will wiggle back off the mounts and most likely hit the coils..so once it hits and stops just lift it up and watch from hitting the bars.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

And gets out an even bigger one, but not for the gas tank...Comment

All above info is good , except the crow bar and hammers. But you may also want to have a piece of 5/16 or 7mm fuel hose that is plugged on one end handy just in case when you remove the fuel line , you find that you petcock don't work

Ideally empty the tank first. Fuel is heavy and sloshing around makes it more difficult to manage than needs be. The overflow line is only accessible with the tail of the tank in the air and going back on some silicon grease on the front rubbers,'hockey pucks', helps ease it on and stops the squeaking as you tighten up the back screw. And you will mix up the vac and fuel lines going back at some point.
The overflow line was missing on my 850 - could have been interesting.97 R1100R
