ZipTy XF+/Evans NPG-R Coolant

This has been on a thread before but I wanted peoples thoughts on a bike already built with an overflow such as a WR450.  I couldn't find much tested data of actual temp changes/improvments at idle or on the move.  Has anyone out there done any testing on their own?  I see more of a benefit for bikes without an overflow due to fluid loss from puking it out.




No need for an overflow with Evans since it won't boil over. When I ran it in my WR450 I removed the overflow to save weight.

Evans does not make your bike run cooler. It prevents boiling and it's low pressure are it's great features.

I personally won't run anything else in my bikes.
