Picked up the bike a few week ago after it had been standing for almost a decade. In great condition for it’s age, changed the plugs and threw in some fresh petrol but she’s running on two cylinders, but not always the same two. Either 1 and 2 or 1 and 4. Any touch of the throttle and she’s dead. I’m thinking its the carbs are filthy but I wonder what you think? I haven’t had a go off her yet and it’s killing me!
