He did say he checked all the passages.

Throwing stuff at the wall now; are the gerotors installed correctly; narrow for pressure side wide for scavenging? Is the separator installed correctly? The return should be checked with return line disconnected and engine running; pouring oil through isn't thorough check. According to one of the HTT posters, some of the early TCs were assembled with excessive case sealant. (Look at the cases and if there is a lot of sealant on the outside of the seam, there's likely as much on the inside.) Over time, the sealant would break loose and block or plug the oil scavenge passage, and cause major sumping.

I've been in touch with the service manager.... Sort of. It takes him a couple days to get back to me and I asked him about the run-out and he didn't know so I'm going there to sit down with the service manager and the tech tomorrow. He said the rep for our area will be down in a couple weeks and he wants me to bring the bike back then. Should I refuse to pick it up and just leave it there until he comes?

So the service rep basically didn't have any answers so the dealer sprung for a new set of cases. Just got finished with it yesterday. Went to pick it up today and its still sumping. I'm at a loss. I still am not sure if they ever measured the crank runout they told me that if the crank was out there would be shearing in the oil pump gears which there wasn't. But isn't it also possible that it could be slight enough runout to cause it to dump but not bad enough to cause shearing?

Pump has been replaced. New pump and cam plate. New cases. Originally when I first brought it in the tech said the oil rings on the pistons were upside down and he flipped them. If he was wrong could that cause it to sump?

You can't install the oil control rings upside down. Are you sure he wasn't referring to the compression rings? If those were installed upside down, no sumping but other issues.
