What Port Is This?

I posted this in the General Discussion forum but it's probably best here.... I think the port without a tube on it shown on this picture of the throttle body should be for one of the two MAP sensors. Does anyone know for sure? Thanks

 

I'd like to but the pipes are gone. A 'mechanic' tossed them.

 

The previous owner was having the fuel tank cleaned and the guy working on it was not making progress so the PO collected the bike. The guy lost some parts. I think I'll just run some thick wall rubber tubing from each MAP sensor to these ports and hope for the best!

 

I bought it in non-running condition with items relating to the fuel tank, throttle cables, air box, and a few other items taken apart or 'messed with'.
