i had one of my sxr's do this. the oil tank was gravity feeding and the carbs would be full when i went for the first start. the check valve in the oil line was the problem. although it stops the oil from flowing in the wrong direction, the spring loaded valve also stops gravity feeding. sure enough i could easily blow air in the direction of flow on the old one, where as the new one i could not.

they are cheap, might as well go new. make sure you put it in the right direction and run some mixed gas for the first time too.
