Have had a water leak for a couple of weeks in my 4bie , so i stopped using it and used my ax for work ....today i took it to my bro-in-law to asses the cause ...having took the cover off realised that the rattling was the water pump that was about to give up the ghost and obviously the belt and my valves with it

..saved just in time , so gonna change them and the tensioners next weekend , just in time for a trip to Ireland .....never driven the 4bie that far before
