Boyer Ignition on the SOHC 4's

[Johnwebley]

I have a CB500-4,

 I have had it since about 1977,its an M plate,

 I have fitted Boyer ignition,its proved very good ,and reliable,
but , some thing that has happened twice in the past 25yrs is worth mentioning,

the general instalation is easy,

but over time,check the connection of the 2 wires on the sensor plate,

I have found the small screws that are the connections for the sensor coils becomes loose,giving poor starting and slow speed running,

 hopefully I have cured my issues using lock washers,

will let you know over the next 25 yrs

I replaced the complete points assembly on my CB750F2 back in the late 70s & spotted that where the blue & yellow wires attached to the laminate back plate of the BB ignition that there was apossibilty that they might come loose. So I loctited the connection so that it would never come undone with vibration
