Hi everyone, I need to do an air filter and oil change on my bike, its a 2005 wre 125, I've got a 10 40 oil from an mx shop but I can't see anywhere that says how much oil I need to put in. There is a small hole in the right hand side of the gearbox a bit lower and in front of where the oil gets poured in, I used this last time thinking if the bike is stood upright and the little hole gets covered with oil, it becomes black, indicating it's full enough with oil, but I don't want to use this method again because I'm not sure if I've used too much oil [last time was about 730 mililetres] or too little? Just thought there would be some kind of marking saying the capacity or is this little hole the only indication??? Thankyou!!
