If you look to the left of the photo; above the bolt. You will see an oil pressure switch that has no wire slid onto it
Prolly just came off while cleaning. I usually slip it back on, and wire tie it against the sender when I find it offThanks Kevin. I'll take a look at that when I get home. Did this just work it's way out or was it not connected properly? Also, evidently that dones't cause the bike to run badly because I noticed it when I got back from a ride.
