I saw a post on water wetter from the CRF 450 forum and thought I'd asked the BRP owners. What's your thought on watter wetter? Anyone tried a propylene glycol such as Evans NPG+? Found at the following site: http://www.evanscooling.com/html/npgPls2.htm The typical water/ethylene glycol boils at 264F but the evans NPG+ boils at 375. I've been having to top off my radiator after long rides and had picked up some water wetter but havent added it yet.
