Hey guys my brother just put a 04-05 450r carb on his 400ex. It runs perfect, the only problem is where the float bowl meets the carb it it leaking gas out of the Seam. I'm assuming the float bowl gasket needs replaced, but is there anythig else that could cause this? it dosent leak u til I rev it, then I can watch the gas seap out. Anyone had this happen?
