Hello everybody, I would like to make an oil change soon on a GN 125 and have now informed me a little bit about it. My question is if a forum member can upload photos here. So where are the appropriate screws for example. I don’t have the machine right now, so I can’t look, but I want to be prepared when I get to it on Saturday. A little something to the background: I don’t have the machine for long. It drives but great and runs from the 110 things. The speedometer shows 32tkm. The only drawback: the idle is almost not to get in. Now I tried to read a little cleverly: It must probably 10W40 mineral oil for gearbox and motor (only one oil circuit for both?!) in and you have the possibility to open 2 screws, whereby one probably falls against one with an idle pin with a spring. The spirits in the net argue whether both screws are necessary at all (if yes, with which Some say that air can draw after it and that the lowest point is certainly emptied. I can’t understand it without photos and without a motorcycle of course. Since the idle is really impossible and I fear a mistake by the previous owner during the last oil change, I would like to check the correct seat and installation of the pin or bolt and spring myself, if the parts are still there and not with the last oil change has been lost. I would then, according to the attached sketch (part 22) lead the mushroom-shaped pen with the round cone first into the opening and put the spring (part 19) on the flat plate, turn the screw (part 25) in the end. Should then be correct, right? I found the photo of the parts on the internet, but on it the pin / bolt seems to lie wrong around to the pen. If someone knows about it and/or uploads photos thanks already for the support! 😉 I’m more of a beginner with something like that and I haven’t done an oil change on my Corsa B, so I didn’t do it on the 125. A nice week, Dominic PS. I drove a few kilometers on my motorcycle yesterday. It’s fun for such a small machine.
