Default 19 SGS Bogs down

I have a 2019 Street glide special with 6k miles and it recently has had two occurrences of acting up after only 10 minutes of riding in the Midwest. Starts out running fine, then after exiting the expressway, it feels sluggish. It accelerates slower than usual, and feels like there is back pressure. Once this error occurs, the bike decelerates more quickly. Also after the incident, riding further, it starts to smoke out of the exhaust and throws codes for the O2 sensors. It will accelerate up past 5k rpm, albeit more slowly, although this would indicate its not running in limp mode.

This just started out of the blue? Any modifications to the bike?

No modifications to the engine, only slip ons.

Start searching the term "sumping" in the M8 Forum here.

Default Plugs




Attached are images of the plugs, genuinely not how I'd expect them to look. And the oil is quite low.

You next step is to pull the crank sensor and see how much oil comes out, and find a way to measure it.

Also look at the data sticker on the left downtube and let us know the manufacture date of your bike.

Do you have a warranty?

It's sumping more than likely, I would bet it doesn't have the 8 lobe oil pump in it. If you are still under warranty I would get it in to the dealer ASAP.
