spewing

so was on the trail first time goin well, and the bike just started spewing coolant out, couldnt see where from, am guessing overflow hose, any ideas why? thanks

I just picked up a 05 fe 550e with 48 hrs on it,all scheduled maintenance done to it,was lightly trail ridden,I've had it out twice and put 75 race miles on it,I noticed oil seaping out of the hose on the top of the head ,next to the front valve cover,the hose clamp is saturated,has anyone...
