zxr750L ignition switch

Bike seems to like turning itself on when im not around (haha) with no key in and turned to the off position and a friend has said it is more than likely the ignition switch.
Any ideas if it could be this or is there something else i should be checkin?

While on the subject of ignition switches for this bike if it needs to be replaced what other models use the same switch so i can find perhaps switch, cap and seat lock.

Kawasaki.com and ronayers.com (reverse part number lookup) are your friends.
