For those with doubts, this is a real problem.
I have a 2017 CVO SG, early model year production with 3200 mile on it.
When the bike had about 2800 miles on it I started to notice that on longer rides it would get extremely hot, sluggish and loose power. I also noticed a smell of hot oil. The tone of the engine changed.
I had heard about this sumping/oil pump issue so I started watching the oil level closely.
Went on a ride a couple of days ago, checked the oil level prior to the trip and it showed full on the dip stick. About 100 miles in, the bike again got very hot, became sluggish and smelled of oil. Friends I was riding with commented that on a couple of red light stops when I accelerated they noticed a cloud of blue smoke from my exhaust.
I stopped at a dealership close by and checked my oil, the dip stick showed the bike was at least a quart low. I thought, no way did I burn a quart of oil in 165 miles. I added about a 1/2 quart just to be safe and rode home. The bike ran very hot all the way home. Oil pressure indicator always showed oil pressure OK, never got a check oil light.
By the way the service manager at this dealership immediately asked me what tune I had on the bike and said that was most likely my issue. BS, I knew it was sumping. He said they have not had any bikes with that issue.
I checked the oil when I got home and the dipstick now showed the oil level was high.
Long story short, Bike is at the dealer now, They followed the service bulletin (1450). Found excessive oil in the crank. They torn it down. Bad oil pump, scoured front cylinder and piston.
Harley is covering repairs under warranty.
This oil pump issue is a real problem. MCO should be issuing a recall.
