i think your asking where the oil check level bolt is. it is on the side of the clutch cover facing the front of the bike. under and to the left of the fill port. thank you for commenting .
Ich denke, Ihre Frage, wo die Öl-Check-Level-Schraube ist. es befindet sich auf der Seite der Kupplungsabdeckung mit Blick auf die Vorderseite des Fahrrads. unter und links vom Füllanschluss. vielen Dank für ihren Kommentar
i use pro Honda 10w30 and 40 (usually 40) in my bikes. just make sure u get good brand oil and that it is motorcycle oil. it lubes the clutch and gears better . think on a car the oil is only lubing the engine not the transmission , a dirt bike is all in one so the oil needs to be very good.
