Fazer 400 New Clutch?

[fazer400]

Hey guys, i bought myself a little 1997 fazer 400 as my first inline 4 last week and i love it!! everything was fine until i filled it up with too much oil. I drained the oil a little bit after 1 day of use and topped it up a little. Ever since over spilling i notice the slutch slipping slightly in gear 3.

Is this a coincidence or would it be normal for a clutch to slip after over filling with engine oil?

Cheers guys
