Does anyone know which way round the two primary chain guides fit in the crankcases on a 1972 CB350f. The photo attached is the lower crankcase with the front of the engine at the bottom of the picture. There is a small hole at one end of the guide, which I assume is to signify which way round it fits, but I can find no reference to it anywhere. With a 50% chance of getting it right the question is have I and which way round does the guide fit in the upper case?
Thanks
Eric
