You can buy a fitted brass junction and a stopper from a local hardware supply store. Then, disconnect the three-way junction of the pair hoses as viewed from the clutch side of the bike. The two that go to the cylinders get the brass junction, and the one that comes down from the solenoid gets the stopper. Fast, cheap. You can also buy the pair block off plates and remove the entire system. The first suggestion reduces downtime. The second course of action is far cleaner and more complete.
