Are you sure it's hitting the cover, or does the cover just have a little clearance cut on it?  If it's actually hitting, you might have a loose clutch boss nut on the main shaft, or the right side main shaft bearing might have too much end play in it.

Play in and out along the axis of the shaft?  Not very much, no.  It might also have an aftermarket clutch in it with plates that are thicker than they should be.  It's probably hitting in the area where the Yamaha logo is.  If you can't find anything wrong, grind a small amount out of that area and hold it against the case cover with no gasket or screws and then work the clutch.  You should be able to feel it if it hits

I'm not sure if it's aftermarket or not is there anyway to upload videos on here? That way you could see what's happening It is pressing where the yamaha logo is but it would need a lot ground off it flexes the cover a lot
