That pumps on its way out mine was leaking at around that milage an i didn't know it till i tore it apart for the winter an i also had a green spot on the floor in my house (wife was pissed) and the foam on the plastic was soaked, on the last pic if you look up behind that housing you will see the shaft and the weep hole for the pump. Had mine covered under warranty. You can still ride with it like that but it will leak when you shut it off so keep an eye on your coolant level, im not saying dont fix it but needs to be looked into soon. Also good practice to tighten all the hose clamps once a year they come loose on these bikes from time to time.
Performance you still havent changed your pump yet? Sorry to thread jack.
Plus look in the maintance section there are a few threads in there on this.
