Thanks a lot!!
I will go to the shop with the joints, I hope that the have.
Greetings!

Thanks very much.
Really i was not sure that i had to change the joints, but advised me that was suitable and due to the low price that they must have (i suppose), i had thought of changing them.
However, if you say that you have 24.000 km and you haven´t change them, mine has 5.000, with what I suppose that it will not be necessary to me.
Thank you very much.

Hello.
I´m from Spain and i don´t speak french, sorry.
Anyhow I follow the forum and the web and extract profit in what I can.
I have to do the oil change to my tw125 2002 and already  have everything what needs, except the joint toriques.
It would need to know the measurements of joints to buy them.

In this image I have the measurements of the part of the oil filter (down image, 3-2) , but not the low diameter of the joint (i need the outside diameter and the low one).
Besides, also i would need to know the measurement of the joint of the drainage screw (upper image, 3)
I would be grateful that someone was helping myself. Thank you
