August 1, 201313 yr Hello there I have a 97 techno and have noticed the gear box oil has turned white any ideas
August 1, 201313 yr Hi Mate I have the same bike and its to do with a seal at the back of the water pump. its about £4 for a new one. Having the same problem with mine at the moment. Hope this helps
August 4, 201313 yr Yeah water in the oil. Source can be water ingress from the water pump seal as mentioned or from riding through water and it getting in through the transmission vent or just from condensation. When oil is churned up it creates an emulsion which is why it turns white as the water is suspended in the oil. Eventually the water settles out into the bottom of the gearbox where it gets churned up into the oil again. You have to change the oil several times to get the water out and you can never get all of it as it settles into the nooks of the transmission. Best thing to do is get the oil all churned up before you change it. That way more of the water will be removed as part of the emulsion. With a couple of oil changes you can get most of the oil out but it takes a few.
