Well  glad you found out what it was,  and it could have always been worse.  Never forget that.  At least you know nothing is wrong with your bike. That alone is a win.

I hate to say this. I really, really hate to say this, but... - It turns 
out that I DID forget a piece of paper rag in the top end while doing 
the valves... Convinced that it wasn't an electrical fault or a faulty 
oil pressure switch but rather an oil pump issue I took it to the 
dealer. The paper rag I must have forgotten was placed under the valve 
chain and must have been grabbed by the chain while turning the engine 
to get the cams in position. Result: Exactly as Ralph described - the 
oil pan was filled with the stuff, jamming the oil screen. Long story 
short - she's back on the street again, running as smooth as ever, but 
boy - it was an expensive mistake...

Thanks for all the advice offered :)
