Hi Guys, 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?...

Hello team TTR Went for a ride last week for 4 days with my new bags on the ttr - I'll put up a trip report very soon.
