ferodo iron brake rotors

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

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. John http://www.peakantifreeze.com/pkextended.html --- kg4bda650 wrote:

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. RM

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. RM
