On peering into the oil tank on my CB750 to check the oil level I spied absolutely nothing. There was plenty of oil in there when I parked it p for the winter, but its all in the sump now having obviously leaked passed the oil pump. I'm assuming it shouldn't do that and the pump either needs a complete rebuild or at the very least a replacement oil leak seal (Part No. 15166 300 000), which is sadly no longer available. Where do I go from here?
