My purpose is to encourage people to do things themselves!
Plus, this is a nice hobby for myself and at the same time I have the opportunity to save a lot of money by doing all the maintenance myself!
I’m not a professional with cars or motorcycles, I just want to learn how to do things myself.
If you do this service yourself, always check the correct instructions in the official service manuals. This is just my way of doing it!
