why bother?
Has anyone here ever heard of EVANS NPGR "waterless" coolant, this stuff is amazing, it has boiling point of 400F degrees and is good down to -10F, and when it does go below -10 it actually shrinks instead of expanding. What else ? Well, it's good for 100,000 miles! So Evans reccomends draining it into a clean pan (no matter what color it comes out) and re-using it for 100,000 miles. It goes for about $38.95 per/gal but this will do 2-3 bikes depending on size & coolant capacity and its well worth it, especially for those on 4-strokes. Keep in mind that Prestone 50/50 boils at 276F degrees, and it boils before it boils over & this creates little bubbles in the jackets which makes "hot spots", Evans doesnt have any evaporative properties. Just thought this might help.

I use the Evans coolant. It works very well, with no boil over issues even under the most demanding conditions. A few key things with the Evans coolant...
1) get all of the water out of the system before you use it.
2) allow room for expansion - do not fill the cooling system too high
I back the radiator cap off a bit to run at a lower system pressure.
Regarding DEX cool or any other coolant, NEVER mix different colored coolants in even small quantities as some of the combinations are very corrosive to aluminum.
