@8828alex Who is your local dealer? If your in South Jersey call BriansHD in PA and tell them your issue. In most cases you can bring the bike on Saturday mornings and wait for it.

 

Before you go to the dealer try this...

Pull in your clutch lever. Look inside the lever bracket (you may need a flashlight) and find the neutral switch plunger. It will be extended when the clutch lever is pulled in. Shoot the plunger with a shot of WD-40 and then using a small screwdriver or other appropriate tool, depress the plunger and let it snap back a few times. What you are doing is trying to clean the contacts within the switch and ensure that the plunger is not binding up.

I'd bet you have a 75% or greater chance that this will fix both of the problems you are experiencing... The no-start in gear and the idle stumbling/stalling.

EDIT: And one other thing to look for while you're at it... When you pull in the clutch lever and look at the switch plunger, verify that there is some clearance between the lever and the switch plunger. You don't need much but some clearance is necessary for proper switch function.

 

Don't mess around with it, it is the left switch pack. Others have reported the same symptoms.

 

Yes, Mess with it. Like 2black1s said, there is a huge success rate by simply lubing the switch button, But I have a different theory as to why lube works. For Transparency, My switch stopped working early on in 2016 and I lubed it with white grease, that exact switch has been on two bikes now and works perfectly with over 39,500 miles of use. The OP has nothing to loose but a couple min of his time, and if it works the reward of not seeing the dealership mechanics is priceless.

 

I posted in another thread, my 2018 did the same thing early on. However I never experienced any stalling or shudder at idle only that it would not start in gear with the clutch pulled in. I sprayed it with WD-40 which worked for a few months. I figured I would just spray it at every wash or after riding in the rain.

There came a point when it would no longer work. I called the dealer and talked to the service manager. She had the parts in stock as it was a big issue at the time. I dropped by the next day and they had it fixed in less than 20 minutes. The switch included a new clutch lever. Hasn't failed since.

 

 

Pretty sure that 2018s have the new idle RPMs set

 

Yeah WHY?

 

Like others, my 17 was stalling when rolling to a stop and the fix was the switch pack. Computer/logic thing I guess. My bike's idle nor ECU calibration has even been changed. Still running the one it was delivered with from Aug 2016.
Also, don't mess with it. There is an updated switch pack AND lever both of which you will not get by spraying WD-40 anywhere.

 

Some of us have dealership derangement syndrome
