Can not seem to fix my head gasket problems on my sons cr 105 big bore.runs 15 minutes then blows water out of the water pump inspection hole(mainly when off throttle over jumps?).cylinder freshly lapped and head fresh after major blow up.went through 2 gaskets in 2 races last weekend and know motor is fried again just hate to look.
