77 KZ650 Low Oil Pressure?

Well, on my most recent ride the light was flickering on and off so I just giggled the wire and it would come on and off (the light that is).

I think it's just grounding somewhere, I'll replace the wire and all should be good... hopefully. I can't see there being an actual problem, I have been riding the bike pretty hard and no negative results.

After reading through some of the more advanced topics in this forum though, I have to say I don't feel like I am doing enough now I need to bore out my cylinders, port my heads, get some better cams etc! There is no end to it!

Attached is a picture of the bike, for those interested.
