Carburettor models

1 On models with an air intake duct over the top of the engine, unscrew the two nuts securing the duct to the rocker cover studs. Release the clip and disconnect the duct from the air cleaner body.
2 Undo and remove the single wing nut and washer on early models, or the twin wing bolts and washers on later models, securing the air cleaner to the carburettor
3 If the air cleaner is retained by a single wing nut lift off the air cleaner top cover. Detach the rocker cover hose, then lift the air cleaner body off the carburettor, tip it up at the front and slide it sideways until it is clear of the long retaining stud and can be lifted away. Recover the sealing ring.
4 If the air cleaner is retained by two wing nuts, detach the hot air duct (where fitted) and then lift the air cleaner body off the carburettor.
5 With the air cleaner removed from the engine, recover the rubber sealing ring if it stayed behind on the carburettor flange.
6 Lift off the air cleaner cover and withdraw the paper element. On the later type moulded plastic air cleaners the cover is removed by prising it off with a screwdriver inserted in the slots on the periphery of the cover (see illustrations) .
