Bought a new 2007 speed triple in early 2008. has aprox 3000 miles on it and have not really had any problems. temperatures have been high in alabama ~ 95 ยด and after pulling into garage and parking without indication of overheating after ~20 mile ride, i noticed a moderate amount of fluid on the floor which appeared to be antifreeze although it was more yellowish brown than blue. my expansion tank was empty. the fluid was exiting from a small hose at the base of the bike but without doing alot of disassembly i cannot find its origin. my service manuel does not show an overflow hose for the coolant system.any thoughts to cause and fix if needed?
