Wow, so you took a 2010 tank and put it on a bike that had a 1987 tank with carbs?
The 2010 tank has inside a fuel injection fuel pump, fuel filter electrical connections etc.
So your probably not going to get any fuel to the fuel outlet without everything being in order and operational inside. Other than a drip or two which wont support the carbs.
Also if you did have everything operational inside, the fuel pressure would be too great for the carbs anyway.
I don't have a break-down of the tank and the interior. I have it in the parts manual for my 08. But if you get someone to scan it they can post it for you. You can see all the parts inside the tank.

You're looking for info that should have been done before you did the swap. Guess I don't have to tell you how important research is before beginning any project.
Anyways, the difference between the two tanks is that the '10 tank is built for EFI and carries a fuel pump inside it and has no fuel petcock. The older carbureted bikes gravity feed to the carb through a petcock which is nothing more than a fuel shut-off valve.
What you need to do is remove the internal fuel pump and also the fitting that the fuel exits the tank through. Then fit a petcock to it and run a fuel line to your carb.
I don't know if this can be done. It depends whether or not the tank bung will accept a petcock and/or if there is a petcock available for this swap.

Check out this article in Baggers -- it details converting a FI tank to a Carb tank utilizing a Pingel conversion kit and also a Pingel petcock. paul
