ok my 2002 426 runns rilly hot. i have a single pwr radiator on it. its off a quad the radiator. well any ways the motor gets rilly hot rilly fast. when it gets hot the water pump leaks rilly bad. also it gets hot and if i stall it or shut it off when its hot it wont start till coold down. now if it runs this hot ill only be good for racing cause races are short. i want to do more than racing.i drive around my house out on my track and it jsut gets way to hot. it actualy feels like its running hotter than my air cooled 400ex motor. is this jsut how they run? hot and hard to start?
