To keep it as original as possible, you could choose to reinstall it. The K75 can be twitchy at low speeds so fitting the damper does improve the handling. You can safely leave it off if you so choose. One reason to ditch it is that the silicone grease that provides the damping action is not available any longer and if your damper is not performing properly, it could impact the steering. If you replace the pointed bolts, there's no need to modify them.
