canada280i Posted July 11, 2014 Report Share Posted July 11, 2014 Yes, oil splashing around the gearbox and a little gearbox pressure forcing a little into the tube 1 Quote Link to comment Share on other sites More sharing options...
copemech Posted July 12, 2014 Report Share Posted July 12, 2014 (edited) It IS a breather and vent, if no excess, no issue. If you tip the bike in a crash, you may get more, and they may also find their own level if overfilled! Tube is best run up over the carb inlet then down to skidplate level. There are other reasons for this as well. Edited July 12, 2014 by copemech Quote Link to comment Share on other sites More sharing options...
