I have been troubled with an oil leak for months but it doesn't drip. Bike is a 2016 that I bought new in June 016. I have 18k miles and always maintained .It runs down the front of my engine and blows up and gets on my glasses, wetting the bottom of the engine. After no success with my selling dealer I have located the source. It is coming from behind the starter motor and running down the engine case seam. It appears to be coming from the seam.
Has anyone else had this issue ?? Any constructive input would be appreciated. TY

 

I have a C90T also and have had leaks too, one form oil drainplug they have a cork crush washer .Then the stator /voltage covers on left side have a rubber crossover which will also leak, but sounds like your describing where the oil filter is !It is in front exactly where you are describing
