didnt kato. the RIO is doing something

My experience regarding long term storage is with KNSU, KNSB and KNDX.
I've used both KNSB and KNDX after being stored for about a year with no
noticeable change in performance. Storage was in redundant zip-lock bags at
room temperature in a relatively low humidity environment (approx. 60% +'/-
10%). I've stored KNSU for long durations in a zip-lock bag in a freezer
with similar results (this is probably your best bet for storage). As noted
by others, *never *store your grains with desiccant for more than a week
or so. The residual moisture is sucked out and the burn rate increases
enough such that a CATO could result when fired (depending on your safety
margin). Moisture is a burn rate inhibitor. I'm guessing but the effect
could be exacerbated by RIO.

What is "old" in this context? And is this KNSB or plain sugar or
sugar/corn syrup or what?

a limited life span in terms if usability. I tested some old motors that
I've recently observed that old fuel (atlest fuel with RIO in it) has
had RIO in it and they all katoed. I also has some old powdered fuel used
for making hand rammed motors and the the motors that I make now with it
all Kato. I made new fuel and it worked fine. I suspect that maybe the RIO
catalises some side reactions that makes the fuel become unstable? Anyone
able to shed some light on what's going on here?
