If you had an oil window on the sump of an automotive engine you would probably say the same thing.
Most likely you are just noticing aeration of the oil from running.
Remove the filler cap and rub you finger on the clutch basket, look at it, wipe finger on a clean white rag, Kleenex, toilet tissue.
Now go wipe some oil off of your automobile dip stick, nearly same-same, I'd guess.
With the engine turned off overnight, one can usually remove the oil filter cap above the oil window with-out making a mess.
Because the oil filter usually drains mostly back overnight. This will allow you a better look.
I will suggest from afar, normal. Ride on! And Welcome to the forum.
And many new members wish they knew how to post a pic on post #1!
