Hi I've got a 2001 Kymco Zing 125cc and am having a biig problem with it at the moment. Please bear in mind that I am a complete novice where it comes to mechanical stuff! I am having difficulty in changing gears, the gear lever seems to stick and I have real problems kicking it up and down the gears. I've tried wd40, and that seems to have loosened it a bit but still difficult to kick up into 3rd. Can anyone give me a clue please?
