not sure if this is an issue but i'll ask anyway on the weekend i noticed my Spada has a little hole (looks factory made) on the uderside on my exhaust just before it meats the muffler. i noticed that it also has an oily spray coming from it when idling with the choke on. It goes away when revved. founf it whenb trying to work out why the drive has oily marks where i had the bike idling :? is this normal..... i was thinking it bay be just unburnt fuel from the choke? should i be worried or concerned??
