If the KLR cooling system holds 1.3L or roughly 44 ounces. If you use 32 ounces of 50/50 premix and 12 ounces of distilled water you have a 63.6% to 36.4% water to coolant ratio.
If this is true what would the lowest and highest temperatures. I don't know and would like to know.
The reason I came up with this ratio is economics.
32 ounce bottle of Pro Honda HP Coolant Premix, $4.39
12 ounces of distilled water, $.07 ($.64 a gallon)
The coolant would be completely used and distilled water is inexpensive and the remaining distilled water can be used for other projects.
