This evening I noticed the gear oil was very white looking as if water was in the oil on me beta so I drained it and put fresh oil in any one shed some light on this cheers 

If you haven't just been riding in deep water then you probably have a leaking water pump shaft seal or a corrosion hole in the water pump housing

Cheers for the reply I havnt being riding in deep water I suspected it was going to be the waterpump seal Is it much of a job to replace I will strip it down tomorow evening 

 

Small job either way but expensive if it's a hole in the casing

Was out yesterday at a practice day checked the oil throughout the day and was not milly or  discoloured
