I think it is the gas tank overflow/vent tubes that go into it. Nothing really emission-wise that would be tested. I would just trace the lines up and either buy new complete lengths at the auto parts store or put get some fittings to extend them to where they come out of the bottom of the bike. If the R3T is like my Classic there are two vents that they connect to on the bottom of the gas tank. The service manual should show you where they are routed.
