Bulldog-BT1100

During last year, after long distance speed driving I notice oil leaking on front cylinder, around exhaust pipe. I think that I find from where this oil come from. On the air box from bottom side is small pipe about 5 cm long and it is going nowhere. This pipe is used to collect oil which come from engine, and my ex motorcycle (Yamaha XT 600) has this pipe, and it was closed at the end, and it is possible to drain this oil from them. So I decide to make something like XT use. See on pictures and I thing that you will get point.
