When Can I Assume Bike Will Not Sump?
Sorry for another sumping question/thread. I am looking for a used 2017/2018 Limited or Road Glide Ultra, hopefully stock. Is there an amount of mileage after which it is safe to assume there will not be a sumping problem? How can I tell if a used bike has had a sumping problem.?

warranty records to verify.
only way to test is outlined in the service bulletin, sb1451 i believe. Ride bike hard, let idle then remove crank sensor and measure how much oil comes out.
im on my 3rd m8 and zero transfer or sumping or any issues other then not enough time to ride.
Good luck

That depends on who you talk to. If someone has experienced sumping, they are going to give a different answer than those who have not.
Roll the dice and take your chances.
Edited to add that the larger the displacement, the more likely it seems to sump. Quite a bit more prevalent on the 117 CVO engines. My 120 sumped one time.

Not many easy ways to tell a sumper from a non-sumper before putting money down. If the owner will let you take it for a 1 hr ride you can get a good idea if you’ll have an issue after you own it. Check the oil level before and after a long test ride. If the oil level is substailly lower after the test ride.... walk away.

Unless you're talking about a Stage IV CVO. I think those are disproportionately likely to sump. I don't know if the likelihood rises to "probably", but I think the risk of sumping increases substantially if riding a Stage IV CVO hard.
