Hi guys So ive recently got a used 2012 zx6r with 12k kmh on the clock, the dealership said they serviced it but the front brake fluid seems to be low and rear brake fluid seems to be enough capacity but is complete black, is this normal? I attached photos

I've had this 1995 for a little while. Everything works fine, but it has no power over 70mph. I had the carbs cleaned, rebuilt, floats adjusted, tank de-rusted, fuel filter cleaned, coils changed, spark plugs and I'm probably forgetting more. I'm still clueless and not sure where to look next.

A quick google search will bring up some discussion on this topic but the answers are mixed. First oil change is at 600 miles, I'm thinking of throwing in Mobil 1 Racing 4T 10w-40 Synthetic and continuing use from there. What do y'all think of this?
