Abstract

Bereitgestellt wird ein Zweitaktmotor mit einem Zylinder (20), der einen in einer Zylinderlaufbahn ausgebildeten Brennraum (27) umfasst, mit einem Zylinderkopf (10) und mit einem Auslasskanal (16) aus dem Brennraum (27), wobei in dem Zylinder (20) mindestens ein Überströmkanal (17) zur Verbindung des Innenraumes eines Kurbelgehäuses des Zweitaktmotors mit dem Brennraum (27) ausgebildet ist, wobei
- der Zylinder (20) zumindest eine axiale Bohrung (50) aufweist, welche eine Wandung des Auslasskanals (16) und/oder des Überströmkanals (17) zumindest teilweise durchdringt, sodass die Bohrung (50) im Auslasskanal (16) und/oder im Überströmkanal (17) zumindest eine wandungsseitige Öffnung (55) ausbildet, und
- in der zumindest einen Bohrung (50) ein Stift (40) anordenbar ist, wobei der Stift (40) angepasst ist, die zumindest eine wandungsseitige Öffnung (55) so zu verschließen, dass die ursprüngliche Oberfläche der Wandung des Auslasskanals (16) und/oder des Überströmkanals (17) im Bereich der wandungsseitigen Öffnung (55) im Wesentlichen wieder hergestellt ist.
