Any one ever tried valvoline super coolant? http://www.valvoline.com/pages/products/product_detail.asp?product=96 I have problems overheating my yz400f no matter how I ride if its over 85 degrees out, and i have a 1.6 bar radiator cap! I'm about to give this stuff a try, I'm guessing its like redline water wetter, but if it cools 25% better then normal coolant like they say, I'm sure it will help me out quite a bit. I'm going on a 3 day ride in sand next week so I will be ack to inform everyone on its performance. Its like 9 dollars for a quart, and you mix it 90/10 so it will make like 2.5 gallons, its a deal.
