As sawfun stated 404 063 is a common chain. I run it in full comp and full skip
depending on bar length. I have never run an 090g so I have not experience
but I would say maybe they would be close. An 090g with a 137cc top end
may have the edge over a 797g.
Don not sure where your info came from on 5 variations. I have had many of
these apart and the only differences I have seen is the 797's versus the supers.
797's have thin rings and boost ports. Early supers have thick rings and boost
ports as well as the Tillotson HL103 carby. Where later supers have thick rings
and no boost ports and the Walbro SDC carby.
