2004 Daytona 600 Leak...

Hi all

I'm still very new to bikes and have a lot to learn with regards to various engine components etc so please be patient

I went for a mildly spirited ride this evening and then once I went home I noticed a leak coming from the left side of the engine

As I said I am unfamiliar with the 'technical' names for parts so not really sure what I am looking at here...the leak was considerably worse however I wiped off the residue to see if it built back up again and it did over the course of about 15 minutes of riding, it doesnt seem to be leaking when the bike is switched off but I could be wrong.

If anyone has or can point me in the direction of a Haynes manual for a D600 that would really help

Can anyone give a novice some pointers, many thanks in advance
