I have an oil leak coming from the front of my engine near the timing chain cover. There is also a sensor near the cover on the clutch/shifter side. Its kind of hard to tell where the leak is coming from at this point. I remember some members telling about changing either a gasket or a seal behind the timing cover. Can that sensor near the cover weep oil? I'm not even sure what its for yet My bike has about 18k miles on it now, does anyone have a guess about the leak?
