My new 1 week old 2018 Roadglide does this. Only 540 miles and has done it since day one. Bounces between 900-1000 with an occasion burp down to 700 or so.

I really think this is normal as my 2018 lowrider does the same.

My 17 RGS also will do this ! But mine shakes more at idle than any M8 I have seen. Dealer said it's fine ?

The clutch switch is bad, take it in and they will replace under warranty.

Does anyone know the SB number for this? Even better can someone attach the actual bulletin?

Thanks!
