He bought my CB77 for parts, but never needed parts (ja, Honda's are good products :P ) , so anyway, bought the 'spare' bike and restored it.
So, while I was pulling the bike apart, I came across these coils..


On one side (can't be seen in these pics) there seem to be some 'original' numbers (not like a long part number, but just some letters) .
I haven't tested the coils, is this some DIY project or is there more to this ? Seen something like this before ?
