Yeah it has coolent in it, ever since the time in France in Lyon when a van behind me was flashing and beeping his horn at me to let me know the bike was pissing coolent all over the floor (cos she was way too hot, and just pissed it out >), so I have always kept a check on it.
I have even had it in with BikeTreads form them to see anything is worng and they cant find anything. :-?
