The hose with the yellow arrow on it is the question. The top is attached to both carbs, there's nothing at the bottom. It don't attach to anything behind the stock air box but is mounted to the back of the front head with a bracket.
It looks like to me that some oil is dripping out of it because the bottom of the front head is wet all the time and I can smell oil burning every now and then. Should I be concerned?
