NEW OEM For Honda Pulse Generator Spark Advancer Springs Part : 30224-437-000 This is for brand new OEM for Honda parts for your 110/125/185/200 series 3 Wheeler or 4 Wheeler Fitment: Nearly For every Honda machine with a Pulse Generator Assembly that physically advances the spark timing. Spring is 13/16 inches (20.5mm) long at rest (not stretched) measured end to end. Note: I'm aware of one model that these do not work on (1972 CB200). This engine uses points ignition instead of a pulse generator. If your machine has points instead of CDI, there is a good chance these springs will not work.
