hey. my motor (125) is leaking oil not really badly but if i let it sit overnight theres a drop or two on the ground.
its comingfrom the rear casing near the sproket i put 15/40 oil in so is not thin oil.

its an old motor and i will be uprgrading in the near future so im not to interested in buying a part for it but would it help to put maybe some engineoil stop leak for cars?
if i put a little bit of that in when i service it? or what if i thicken the oil?

any idea's much appreciated:)

Thanks
