where did it spit it out of?  the front of the quad, the back of the quad?  

 

i had pinhole in my rad, and it wouldnt leak until it started to heat up and build pressure.

From front it never done it before but never reved it for that long Iv checked there no bubbling  in radiator and pressure tested it when it was cold and not running and never dropped

Bad radiator cap?

if he has the tank in the back with the hose hooked up, it wouldn't be a leak in the front.
