it's a beautiful tank, but the bottom doesn't look anything like the one on my '00 m900 - you sure it's for a fuel injected bike?
That was my first thought as well.
The more I think about it the more I think you're right.
Does not fit on the '97 carb monster in my garage, so I think it must be FI. If you have more insight than I let me know.
What about it doesn't fit?
The two nipples to the left of the hinge are for the vent and overflow drain tubes, the threaded hole up from that is for mounting the bracket for the fuel filter, and the nipple that sticks out of the side of the tank is for the supply line.
If it were fuel injected it'd have one more hose nipple for the fuel return line.
I just went out in the garage and looked under the tank of my roommate's '97 750 and it looks identical to the one in your picture.
