Hallo frage hast du diesen motor noch

[@massimocicoria7591]

Dovresi mettere il collettore di scarico tubolare , poi la marmitta a risonanza e accordarla , usando le dovute misuse.
In questo modo sei troppo corto il motore non spinge.
Saluti e buon lavoro

Hi, thank you for the comment. This run was done long time ago and with not fully opened throttle just to see how it runs. I will share another run with this engine soon, showing a little bit more power. 😊
