I had a 02 800 with a cracked neck, I replaced with a used one I found off the swap meet here, I would think you could use black gasket maker silicon to fill crack, once that dries cover with shoe goo, I think the best fix is replacing as I was afraid of hitting with my knee while riding and have the whole neck come off. By the way my 09 M1000 has the same issue that developed over the summer. Sitting in a enclosed trailer, went to move it around and noticed gas. Cat is replacing this tank, just part no labor, I found a good dealer in IA to take care of the replacement tank.

I just fixed one,but have not tried it to see how it will hold,but the repair fit very snug, looks good, my neck had snapped off completely below the threads.I went to the hardware store and purchased a pvc coupler,and a product called seal all. Hit every thing with 80 grit paper and green scotch pad,then took a dremel and cut some veins on all sides to allow glue a better place to lay.Sand the pvc well as it fits very snug.Seal all is gas and oil resistant.Be sure to seat pvc down in the neck at least 1/4" or the gas cap gasket flange will hit,and not allow the gasket to contact the neck.Think I'm into 8 bucks a biiiiiiiiiiiiiiit cheaper then a tank.

I've got a broken neck on my 01 also. After doing some research I've discovered that a 2" PVC (white plastic) plastic pipe coupler is 2 3/4" od. Just the right size to fit in my neck. I'm going to coarse sand the outside of it and the inside of the neck, then smear a bunch of JB Weld after trimming to length and shove it together.

White colored PVC will not degrade in gasoline unlike the back ABS pipe.
