I learned a new word in my HD vocabulary. It is sump issues. Returning from a ride to the Black Hills on the last hundred miles my 2018 triglide stared to lose power and was burning a lot of fuel. When I got home I checked the oil and it had a burnt smell. My dealer Historic Harley in Topeka Kansas tore the motor down and determined that nothing was wrong or damaged except that my motor didn't have the updated oil pump that the 18 models should of had that was supposed to fix the issue of oil not being removed from the sump quick enough. If the oil in the sump starts running above 8 ounces it can affect the flywheel and cause a loss of power and cause the oil to get too hot. No lights or codes thrown. This makes me wonder how the manufacturing process actually works. When I get this trike back ( has 10k ) I plan to put it through some real tests because I have a feeling it isn't going to be the same as before I learned this new word. Prior to the 18 I rode a 10 and put a bunch of miles on it with no issues. The 18 in my opinion was far superior in performance versus the 10. Hanging out at the Historic Harley Dealership is a pleasure due to the Evel Knievel Museum being there, a BBQ Restaurant, and coffee hangout for us old guys. Also I might add they are a great dealer and have a top notch service team. Hopefully this will turn out as desired because I’m getting too old to experience a high level of stress.
