The bike does not pressure test the scavenge side pump only feed side pump.
It does sound like once the motor sumped, it couldn't stop. Wonder if the high temps resulted in killing the antifoaming properties or even simply the viscosity of the oil so that the sumping does not stop.

Not my bike, but another M8 Sumping... The owner of the company I work for just bought a new 2018 Limited CVO (Red). He had the dealer install stage 3 or 4?, not sure which. Bike has 700 miles on it. Sumped... Now he says the dealer is telling him that the MoCo voided his warranty for the map that was installed on his bike (by the dealer!) and that they can't "replicate" the issue... I emailed him the TSBs for both issues and sent him the link to this M8 forum. Said, there is a wealth of information out here. Man... I'm glad I have resisted the temptation to upgrade. I've read a lot of stories on here about these issues, but now know someone personally that is experiencing them.

Nope he does not, he sold a CVO SG a few years back hasn't ridden for a few years. He decided he wanted to ride again and bought the CVO Limited. Honestly... talking to him this AM... I think he's done with HD. He's just wanting out from the bike and I can't blame him one bit. Wish he would have talked to me before he bought it, I would have guided him to this forum. (Not that that would have stopped him) He's got mighty deep pockets and the money isn't anything to him (He's got more toys then I could ever dream of owning...) it's more the way he's being treated from the MoCo and the Dealer. I'll have to see how this plays out.

He's been keeping me pretty up to date on this all so I'll report back as I know more. Right now he's pretty fed up... Remember all the work was done to his bike by the local dealer (Which I stopped going to for service years ago)... It will be interesting to see how this all plays out. Again, I sure am glad I waited. I'll see what the '19s bring... Damb frustrating I can only imagine...! $44k+ bike and can't ride it... WTF??

I have in the office 6 different pump designs. Many of them have the exact same part number on them as HD did not change the part number nor add a version number. For awhile they were adding small marks on the pump body but at some point stopped that too. So this is why its hard to track them all as you can get the same part number today as you could before but they are different pumps. Thats just why with the current part number you must also look for date code on the box. So the Service bulletin doesn't come close to telling the whole story.
Now in the past every manufacture I know of revises the part number when the part is changed! HD used to do this as well, but for some reason has stopped and just decided to change the part and leave no paper trail it was changed!

GM did that **** with a none part number change with there ignition issue a few years back and tried to hide the issue. Eventually the truth came out, but unfortunately it wasn't until after people had died. They should have did a recall on that a year before it happened. And what did our Government do in that case? Gave GM them a slap on the wrist. No jail time for anyone. Which makes no sense because our same government put a few people in jail from VW for screwing with gas mileage. Come on VW gets jail time for bad diesel gas mileage and GM only gets fined for killing people. Ok I went off on a tangent sorry. :-)

Ya, I'll see what I can find out. I'm pretty sure he got the high flow SE system put on because a previous conversation to this one, I know he said he got his bike back and it didn't sound any different. He said he called the dealer and the dealer said, well didn't anyone tell you that there are still cats in the slip-ons(I believe were his words) I'll see if I can get anymore info. I don't see him real often as he is the owner of the company and not around too often :-).. But I'll report back what I find out next time I talk to him. I know he also did say he got the dyno chart back. So ya, I'm assuming it was a map, but no idea what ECM was used... etc..
