Yamaha MT-01 Oil tank completely full and chips in oil

Hello, we have here an MT-01 with just under 11 tkm on the clock, at which chips are now in the oil. It all started like this: After a small AU drive (about 50 km) we checked the oil level again. Much we noticed that the oil tank was completely full, and if you unscrew the track rod with the running engine, spray the oil against you. If the engine is standing, the oil was then just below the GFwinde of the track rod. Our first thought was: Sure, too much oil has been filled, so sometimes a The amount of oil went well, but there were chips in the oil in the size of sand grains. Do you have any idea what could have happened there? So the cart would have to have 2 oil pumps. Can it be that only the return pump works and the normal one no more? Warning lamps didn’t work during the ride either. We really don’t know any further
