I do love my twin carbs was going down the motorway seen a scobby so decided to nail it and put out some flames just as I over take him. I get off the next junction as I approach the roundabout I hear a beep it's the scobby, so I undo my window matey says u had all this sparks and 1 1/2 foot flames come out the back. I just played innocent "did I" laughing like f00k to myself as he drives off !
