BMW F800R Waterpump replacement & service

Here I show how I replace a waterpump on a BMW F800R. The oil & water have mixed, as shown by the high oil level and brown colour of the oil. I flush out as much old oil as possibly by filling the engine up with clean petrol. It may take 2-3 oil changes to get the water out completely. The oil in the coolant system can be removed by allowing the coolant to overflow in the radiator while warming the bike up pushing the oil out the top.
Not shown in the video, the 2 water pipes started leaking after a test ride of the bike, and the customer ran into an issue with the thermostat. The oil cooler pipes were very rusty and I capped off them but didn't have time to film it.
