Hi I have a gas gas 125 pro 2011 does anyone else have or had this problem, the oil from the gear box is trickling out of the breather pipe, just emptied the gearbox and refilled it with 400ml, is level halfway on the glass it's not coming out in bucket full and got a good 350ml out when I emptied it thinking there must be some left in couldn't possibly get the lot out could it be the crank seals, they were replaced only 12 months ago, when we had gearbox problems (selector) any advice app
