Water in oil
Headgasket leaks are pretty common on those engines. Have you seen any signs of overheating? Usually when the headgasket goes bad you will get combustion gases into the cooling system along with some of the symptoms mentioned above. I would suggest that you fill and purge cooling system and start it up with the filler cap off. If it blows a lot of coolant out of the filler neck before the engine is properly warm, along with bubbles, it probably is a bad headgasket. They are pretty easy to change. Another way to identify a bad gasket is to get one cylinder at exactly TDC and apply air pressure through the spark plug hole. If bubbles come out of the cooling system, then you know which cylinder/s are affected. I bought a Mule that the previous owner had put a new water pump on. It continued to overheat because of a bad head gasket. I changed both gaskets and put about 1500 more hours on it without any issues. I "resurfaced" the heads by putting sheet of sandpaper on a really flat, smooth surface, and sanding the heads against it using an orbital motion. The sanding marks will tell you if there is a real problem with flatness. I don't remember if the water pump seal is between the coolant and the crankcase, but if so, you may be on the right track there.
Good luck, and do let us know what resolves the issue for you.

Water in oil
I am not a fan of Bars-Leaks, it can plug radiators and small passages. It might fix a small radiator leak, but that's about it. The water pump on the Kawi V-twin engine is driven off the camshaft. On many smaller water-cooled engines this is common. There is a seal between the water pump and the cam drive. If this seal fails, radiator fluid will get into the crankcase. On my motorcycle, there is an air gap between the pump and the crankcase, with a weep hole, so coolant will not get into the oil. I will verify how the Kawi is set up as I have two of them lying around. Look at procedure for changing water pump. It's a bit of a pain, but not that bad.

Water in oil
Yes, I think it likely now that it is the seal on the inside of the water pump. I looked at one of our engines and there is no air gap between the pump and the crankcase. So if the seal leaks, it will leak coolant into the oil. Higher pressure = more leakage. At 750 hours, you're probably due for a water pump anyway. Just be sure you purge all air from the system after replacing it.
