Just posting this in case anyone has a similar issue. A very simple fix got me a good deal on my bike (mostly b/c the seller thought he was sticking me.) Skip to the last paragraph if you just want the fix.
When I went to pick up the 750, there was a small drop of oil on the bottom of the pan/drain plug.
The owner insisted that it didn't have a leak and we wiped it off before I took it out for a test ride. When I got back there was no oil, so I assumed it was sloppy maintenance b/c he had recently changed the oil and filter.
I took the bike home and let it sit on the side stand. The next morning, there was a tiny drop of oil again. I emailed the seller asking AGAIN for a description of any maintenance he'd done and since he already had my money to come clean so that I could save more time and money troubleshooting. His response was basically that the bike was sold "as is" and I've become convinced that he dumped the bike b/c he thought it had a big problem (he was the second owner in 2yrs and 4k miles.)
I tightened the pan bolts and the drain plug a little and took it out for a ride. Again, a tiny bit of oil. Not enough to call a leak, but still unacceptable to me.
A little bit of research led me to an O-ring around the part of the water pump housing that goes into the motor. I took it up to the local shop and we pulled it. Sure enough, the ring had been installed incorrectly from the factory and had a small twist in it that caused a flat spot. Oil would weep around the O-ring, collect on the bottom of the water pump, and then run down the oil pan to the drain plug.
In the end I spent $20 for fresh oil, an o-ring, and labor...and I was out the door. There has been no oil since Friday. This bike is now "cherry" .
Let me know if anyone has a similar issue...glad to help if I can.

If you think that loud pipes save lives, imagine what learning to really ride that thing could do.

It'd be different if you'd done the work yourself, took lots of pics and posted it as a tech article.
Yeah, I started to do the work myself but when the water pump didn't slide out easily, I didn't want to force it. As it turns out, another few pounds of pressure and she would have slid right out. It was a good excuse to visit the shop and BS for a while anyway. Besides, I'd just changed the oil and filter. Pulling the pump dumped the new oil and the shop gave me a fill-up for free. She now has Honda blood (Respsol .)
Here's the link to the article that helped me, with pictures:
I just wanted the info out there in case someone has a similar issue on ANY bike. It can be fixed in about .5hrs of your own time + the cost of the O-ring.

Glad I found this thread... think I might have the same problem.
I bought an 07 GSXR600 recently... it's a wreck with light damage that I plan to fix and re-sell. Like you, I didn't find out until after I bought it that there is some oil "seepage". On first inspection, it looked like it was coming down out of the oil filter, so yesterday I changed the oil and filter and popped a new crush washer on the drain plug. I wiped everything down and was surprised to come back to the bike an hour or so later and see a single drop had collected on the bottom of the pan. The amount is so small that I can't see where it's running from, but my next strategy was to change the oil cooler o-ring.... I'm thinking now I'll try the water pump route. Seems to make sense.
Now... If I lay the bike on its right side can I perform the switch without spilling out all my new oil?

Well I found the real issue, and it ain't the water pump.
I pulled the water pump... o-ring looked fine. I think the previous squid owner enjoyed burnouts as there was gobs of rubber residue to clean up. water pump.jpg wp o-ring.jpg
I initally suspected that the oil cooler was leaking, so I pulled that apart to change the o-ring. Doesn't seem that this was the problem either. oil cooler.jpg
On closer inspection of the oilpan I noticed an impression on the one side. I pulled the rad and headers to get at it. flapper axle.jpg apart.jpg
Seems that when the bike went down the muffler pushed the exhaust into the pan, and the axle housing for the butterfly valve banged into it and cracked it slightly. That's where the oil's been oozing out of. oilpan.jpg
So now I've got to decide how to fix it. Can it be JB-welded together? Do I need a new pan?
