I am a master of micromechanics in a public highschool. I send you my greetings from Bienne (Bern), home of the Watch: Rolex, Omega and Swatch ... I teach teenagers the conventional mechanics and CNC. You can imagine that my training program is entirely focused on 2 and 4 stroke engines. These are excellent objects to learn all the traditional mechanics. Later I will show you our work. Have a nice day. Life is beautiful on a V-Twin.
