GS750 77-79 Different material used in production when making the clutchrods?

Hi!

I have noticed that s ome clutch pushrods are steel and some others are
made from aluminiumwho also is lighter in weight.
It seems that some versions made later are made
from aluminium and many orginals that was
mounted in the engines from the 76-77 orginaly
was steel.
It also seems that the steel ones could be a little more noisy.

Was this change done by design for some reason by Suzuki or whatever?

i think they are are steel as standard, might be wrong though. i doubt a steel one would be noisier if it is all in good condition.
