Took my 650R on a cross country ride the other day. We covered mostly jeep and forest service roads totalling about 85 miles. The jeep road was fairly technical however, rutted rocks, 1st and 2nd gear stuff for at least half of the 85 miles. When I got back I noticed that I had lost some coolant. It was at the high mark when I started and now its down below the low mark. I can't smell any coolant and it hasn't boiled over when I'm riding. The oil looks clean on the stick. The bike is uncorked and I'm running a 1.6 cap with devol radiator guards. It was warm here in AZ that weekend, probably mid 90's. Any ideas?
