My 2017 Tri Glide just turned 3600 miles and this last week i have noticed that it is starting to surge on idle,now I know that the idle has been lowered to around 850.But after it has gotten up to temp when pulling up to a stop it will drop to around 500 then up to 1000 then back down to 500 then it will go back up to 1000 the settle in around 850.Going to call the dealer today and see if i can get it in this week,got a trip planned for Memorial Day weekend.Other than slip ons it is all stock.Anyone else experience this.
