Hi guys I have just bought my very first BIg Bike(if a 600 is a big bike??) only to find that the gearbox oil is very milky having read some of the other threads they mostly point to a water cooling problem , But I dont as far as i know have a water cooling system I was lead to believe it was air cooled so where is the water coming from?? also when the bike gets hot I have noticed that that the overflow pipe that leads to the airbox is seeping quantities on milky water/oil mix should i be concerned or is just that the bike may have been in a showroom for a while? please help!! I wish to go back to the seller fully armed with all the info i can! Many Thanks.
