Turk old friend-
I have tried Water Wetter in many different types of cars including 125 and 250 shifter Karts and have noticed NO difference in temps from not using it.
I can only tell you what I have found - trust me I WANTED to believe that it works.
Perhaps the reason that it SEEMS to work when a comparison is made as you did is this: 100% water is a way better coolant than a water and anti freeze mixture. Adding anti freeze to the mix only delays the point at which it will freeze solid or boil.
In my car, which is in a higher state of tune than yours - higher compression mainly - runs as cool or cooler than yours.
I use distilled water, a waterpump lubricant, and about 10% anti freeze.
Perhaps we both believe what we believe just as fervently - maybe we are BOTH wrong!
Pat
