Random Plugged Rubber Hose Lines?

Just bought this fz6r last week and noticed 2 rubber hoses that go to nothing above the crankcase. They are both capped off but wondering if I should be concerned? Never run into an issue like this on my prior motorcycles. Vacuum sync tubes are my only guess. Thanks!

There should actually be 4 of them (assuming they are similar to the 2nd gen R6). One from each throttle body. The #1 and 2 are connected together and #3 and 4 are connected using that plug fitting (just to keep them tucked up out of the way and not flopping about). And yes, they are used to sync the throttle bodies.
