Hi! In winter i completed engine conversion... from 883 to 1200 + placed mikuni. Everything is fine... runs great... quick throtle response... but...BUT i have noticed that after longer runs 150..200km nonstop... or in city if its hot and i need to make my way in trafic jams... oil starts to leak or more like drips come out from tube that comes from engine for..us i understand ventilation... as i remember (when taking bike appart) this hose was not connected to anything... just free behind the oil tank... should i worry? maybe i should just close it dead? oil level is normal.
