Sounds like you have the clutch switch problem. mine was doing the same thing when hot in traffic,does it start in gear when you pull the clutch in?

 

It does start, but jumps.
I have spoken to the Harley dealership about the recall and am waiting for them to schedule me.

 

What makes it jump is the many plates and clutch disks sticking together until without the clutch spring pressure are allowed to part when the clutch cage is rotated while starting.

 

So does the clutch need attention, other than the recall?

 

That jump is something normal. The newer bikes you have to apply the brakes and pull in the clutch for the start. You might not feel that bump forward like that.

 

This quote is from Service Bulletin M-1436, 2016-12-13. It related to M8 motors which is what the OP has - a 2017 Tri-Glide.

The 2017 Milwaukee Eight engine warm idle speed is 850 RPM, but the idle speed can vary depending on other factors including electrical load on the vehicle. When EITMS is active on this engine, the idle speed will increase to 950*1000 RPM until EITMS is deactivated

Not sure how EITMS affects idle speed on Twin Cams. There may be a service bulletin on them also.
