Another Rad/cap/boiling issue...

While this is true, I would not recommend it if you park your Rocket in an unheated area where temps get very cold (like where I live)... 30/70 protects you down to 8.6F and 50/50 down to -35F. Since I live in an area that often gets down to -40F in winter, I have my antifreeze water mix slightly higher than 50/50 checked with a hydrometer. In this instance, more is better. If you live in the south, who cares.... ride
I'm in the UK and she sits in a heated garage when not in use so less of a risk where I am :)
