Recently bought TTR250 2008 (17k kms) and noticed a small oil leaking from the left corner of the bottom gasket. My mechanic recommended me to just to leave it as it is if it won't get worse and look after the oil level. It's fine for me but still a bit annoying.
Any clues apart just leave it as it is?
And another just a general question-how often you guys would recommend to change the oil if using only in the city? 1k kms?

I use my TTR for trail riding and tend to change the oil when gear changing starts to get a bit stiff - usually long before the recommended service interval
