I switched to engine ice to make my bike ready for the summer here in TX. I went out about a week ago and rode some woods trails and the bike boiled over on me 4 or 5 times. I flushed the cooling system out several times and installed the plain old Prestone antifreeze that states that it will work with all colors of antifreeze. It also claimed to protect aluminum radiators. I substituted several ounce of the antifreeze with Water Wetter. I rode all day yesterday in the woods and it was warmer outside than the previous outing. I could tell that the bike was getting kind of warm at times, but it didn't boil over once. Oh yeah, I bought the premixed antifreeze if anyone was curious about that.
