It is right next to the battery. I thought this was fuse box. Googling it gave different result. I am modelling a Harley davidson and need to understand some parts.
That to me looks like an air filter box.
I reckon that’s the oil tank. If you look on the other side of the bike there should be a filler cap.

Air filter usually sits next to the engine on bikes.
Yeah, realised the more I looked at it. My air filter sat there but the carbs were behind the engine. My older trials bike did have an oil tank there (2-stroke).
