    What are the extra threaded holes on swingarm for? (not spool location)

    100cc engine oil overfill

    My RC 390 only shows correct engine oil after a ride, so I ended up with 1.8l of engine oil and now it's showing higher level after a ride. I was wondering if there is a way to drain extra engine oil without opening the drain bolts and how bad is to have 100ml extra oil on RC 390?
