Engine went due to sumping

[kingfish108]

Update

I have put 4500 miles on the engine repair and all appears to be fine. Actually seems to run a little better than it did before. I did try to trade for '20 TG when I went in for my 50k service. Salesman showed no interest in doing a trade after he found out that I have no payments and would be paying for the new one with cash. I went ahead and had the 50k service done along with a new front tire. His loss. The next day I traded my 10 month old '20 car for a '21. The car salesman had no problem with a cash trade. I have decided to just keep ride my '17 till I quit riding or it dies.

That is fairly well how I feel we're riding th old 09' till it or I die. Great choice Fred

Harley 2017 and 2018 sumping much bigger issue than Harley will admit

My 2017 TG is now at the dealer with the top end removed from the engine. Lost oil pressure last week while out on a short ride. They are replacing the oil pan, oil pump, lifters, pushrods, cylinders and pistons. Pistons were pretty scarred and everything had that burnt look. They said that this is only the second stock 107 that they have seen with a sumping issue and both have been trikes. I have almost 49k on it. I looked into paying the difference to do an engine upgrade, but have decided to ride it to the end of the season and trade for a new one. Really glad my wife talked me into the extended warranty, which ends in January.

My 2017 Triglide with 107 had sumping problems twice. The first time in 2018 my Harley service tech may have not know about sumping yet and replaced both pistons, rings, cleaned up heads from massive carbon build up which actually caused a tapping noise like loose compensator. The second time in 2019 it became so bad I barely made it back to Wisconsin. The ESP adjuster witnessed the rods standing up in the case (tight enough to remain upright and rigid) which means to them NEW ENGINE. The replacement was a 2019 107 with the latest upgrade oil pump and whatever else. After losing 3 months of riding over 2 seasons (short in the north) I traded for a 2020 Triglide Tahitian Teal not trusting the 107 crate in my 2017. I researched forums for about a year and sumping pops up fairly regular. Checking with numerous service depts in Wisconsin and when asking them about sumping they all played dumb and of course will lie to your face saying "it's only the second one we have seen like this". Figure the consequences of a national recall! Service depts are required to keep hush, play dumb, and address the sumping problems on a case by case basis (not to upset the apple cart...I mean Wall Street! The oil pump (sumping) problem root cause was pumping more oil into the crankcase than what could be removed. Oil level rose, the crank splashed in the oil foaming it up causing a lack of lubrication to the top end, everywhere as oil pumps have a hard time pumping foam! It was a huge costly design flaw from the get go with the first M-8 engine. My life has been product/process development and product engineering. This was a CLEAR case of insufficient testing before new product introduction. I consider it Harley's biggest blunder since AMF was at the controls! Anybody else have sumping with comments to share???

My 2017 Tri-Glide stumped on me twice ...But before i had them look at it ' I got rid of it....Mainly because every 8 hundred miles or so i had to bring it in for Oil Transferring...
