Recently purchased a 2012 Ninja 250, took the farings off for the first time, and noticed that the petcock had been set to prime by the PO.
The vacuum line is not connected to the petcock either. There's a tube coming off the carb that's just hanging loose (what I presume to be the vacuum hose?)
I looked up some pics online it would appear that the vacuum hose is typically connected directly from the carb to the petcock, this is not the case on my bike. There's a T coming off the line and one end seems to be going into something underneath the gas tank at the front of the bike.
Should I just hook up the hose, set the petcock to on, and see what happens? Is there any risk to doing so? Zero experience working on bikes before, so forgive me if I'm way off base with any of this. Pic below for context, the hose on the right side of the T connector is disconnected.
