engine case crack
I rode my 2009 klx250s to work today and about 30 minutes after I parked I noticed some oil on the ground. After taking the skid plate off I discovered there is a hair line crack along one of the bolts and it is leaking. My bike has less than 1000 miles on it and I just stated to ride it again in the last 2 weeks.
was a valve inspection/adjustment done recently?...my valve cover was just layered with thick silicone...i had to carefully scrape it all off before adding a new sealant and putting the gasket back on....

Not worth the trouble to get in there to do something and then reuse the old gasket. The '09s had a batch of bad gaskets that would shrink when removed the first time. The best cure is replacement; using a bunch of sealant might cure the leak but make a big mess or cause more problems (excess sealant ending up where it shouldn't be at all).
EDIT:
Good idea on checking the valves while you're there.It'll give you an idea how things are. Write down the results for future reference

The original valve cover gasket shrinks. When I installed the big bore kit I had to order a new one. The new one doesn't shrink, when I checked the valve clearances I was able to reuse the newer one. The head had traces of sealer from the factory so I did my best to copy their technique. No leaks found.
