[dirtbike77]

ever since i put the paul turner racing head on the bike its been seeming to spit cooloant out of the over flow hose.. u probaly wondering why i dont have the lil container right well i removed it. even when the bike is cold and i crank it up it and when i hit the thorttle u see coolant spewing out?

someone correct me if i'm wrong, but it sounds like the head or cylinder may be warped or there are grooves in the head where it has been cut and not smoothed out correctly. i've heard of this once before but don't know if i'm right. if not ask MR. ATC he would know.
