2017 Harley-Davidson Flhtcutg

While riding at 55mph the bike suddenly lost oil pressure and started blowing an enormous amount of smoke out the exhaust and the breather tubes in the intake. This caused oil to come out and blow back under the rear tires which could have resulted in loss of control. I was able to stop and when I checked the oil the cap blew out into my hand because of crankcase pressure. The oil level showed it was very low so I added 2 3/4 quarts of new oil. After cooling down the trike ran ok and I was able to ride it home where I checked the oil again and it had the same crankcase pressure however it was now showing overfilled 2 1/2 quarts. The problem is that the oil built up in the crankcase and was not pumped out back to the oil tank. This is known as sumping which is affecting some 2017-2019 Harley’s with the new Milwaukee 8 engine. As I stated before this could have caused loss of control resulting in an accident with a less experienced rider because of the oil blowing back under the rear tires on the trike. I am 70 years old and have been riding since 16 years old and I believe my experience helped me knowing what to do when something like this occurs. There are service bulletins explaining this problem however I firmly believe all 2017-2019 Harley Davidson Milwaukee 8 motorcycle’s and trike need to be recalled and repaired with the updated parts that Harley Davidson began installing in all 2020 and newer Milwaukee 8 engines during manufacturing. Someone may likely lose their life as a result of this know problem.

OIL PRESSURE SWITCH WORKED IT'S WAY OUT ONLY INDICATING LOW PRESSURE BY THE TIME WHILE RIDING. I GOT IT TO MY DEALER AFTER THEY TOLD ME TO BRING IT IN WHEN PARKED THE SWITCH WAS OUT FAR ENOUGH TO CAUSE THE OIL TO POUR OUT. IF THIS HAD HAPPEND WHEN RIDING IN MY OPINION THE ENGINE WOULD SIEZE CAUSING THE WHEELS TO LOCK AND THROW THE RIDER OFF THE MOTOR CYCLE CAUSING SERIOS INJURY OR DEATH TO THE RIDER AND CAUSING AN ACCIDENT OF THE VEHICLES BEHIND. THIS IS ON THE NEW MILWALKEE 8 ENGINE. HAVE READ COMPLAINT OF THE FAILURE BUT NOT ON IT WORKING IT'S WAY OUT. NOTIFIED HARLEY DAVIDSON REQUESTED AN ENGINEER BE SENT TO LOOK AT THIS PROBLEM,WAITING ON A REPLY
