cooling system flush

Did the 2nd coolant flush to my A-14. Which consisted of draining
the old out, refilling with "reagent grade" (very pure) DI water
running the engine to operating temp, re-drain and refilling using
Kawachem Coolant and DI water. 70/30 water mix
On this flush I noticed I had some soft residue on the bottom of the
reservoir, almost like a mold growth. It cleaned off easy.
Any of you noticed the same? What is the residue?
What brand of "Aluminum Safe" Coolant Flush is the Choice
Recommendation amongst the All Knowledgable Collective? (bowing head)
Regards
Peter

I think that all DexCool compatible coolants are aluminum safe, though
you may want to ask our senior research assistant, RM, about that. I am
running Prestone 5/150 extended life (in the silver jug) that's orange
colored. $6/gal at my local auto parts place.

Peter,
I have been using a 50/50 mix of distilled water and
Peak Extended Life Antifreeze without a problem. I did
not notice any residue when I drained mine.

Senior Research Assistant. Heh. I'll go with the first syllable of the
third word but not much else.
DexCool is supposedly safe for all SI-engined automotive cooling systems
regardless of composition. However, I've seen where two different sources
have indicated that it does not properly protect the lead solder used in
the older copper/brass radiators. Does anyone know anything about the
KLR's radiator construction?
It seems that 9 out of 10 KLR radiator failures are from crash damage, and
10th one gets plugged up from a lack of maintenance. The bottom line is
that you can probably get away with damn near anything.
Hell, I've been running a silicated coolant for well over 10k miles and my
water-pump seals have yet to go Tango Uniform.
The Kawachem coolant is not all that expensive when you consider how
little of it the bike holds. If it'll help you sleep better at night,
just get the Kawi stuff from your dealer and be done with it.

I would be very interested in hearing from anyone who tries these rotors.
Cast iron rotors are supposed to have a significantly higher coefficient
of friction (about 20%) than the low-grade stainless mystery-metal that
most modern bikes use. This could be a nice low-buck brake upgrade for
our bikes.
