Strike 1 of something potentially wrong.

How much cleaner and what kind?

Strike 2.

And no it's not normal. You may what to inspect further into the metal shavings in your oil. Metal shavings usually means either you crank or something else is gone to shat.

Does the motor make any loud clacking sounds?

If so, check your oil screen, so you can rule out a crank bearing. For more info on this issue, see this thread. https://www.ninjette.org/forums/show...ght=oil+screen
