Any update to the M1517 service bulletin? I have a 2018 FXFBS and it had a code for P0374. The fault code was a historic one and is related to the Crank Position Sensor. Bike was still able to start and run.
I called a dealer and they told me very minimal about the service bulletin. Basically the original CKP P/N: 32700048 and the new one is P/N: 32700144
It would be nice to get my own eyes on the document so I can determine if this is possibly my issue of a bad part.
M1517: Milwaukee-Eight Engine - Crankshaft Position Sensor
Okay...nobody got anything. So I went to the dealer and they were nice enough to print off the M1517 Service Bulletin for me.
Lucky for you guys I scanned it in so all can take a read.
It looks like the new sensor gets a new P/N along with a creme/white color housing instead of black. There is no mention in the SB in regards to any fault codes--such as P0374 of the suspected original CKP, but I think to use the new updated part instead of the old one. The wording is a little funky in comparison to touring and softail models in terms of what sensor to use. At any rate, the sensor is located at the front-bottom of the bike with an awesome two-pin Deutsch connector that's easy to disconnect. Since the signal generated from the sensor is sinusoidal/square-wave, the wires need to be a twisted pair in order to avoid any interference on either leg.
Rusty water in swing arm. Basically the drain hole in the swing arm is covered by the plastic belt guard - should be a hole in the plastic belt guard, but there isnt. It is a relatively easy fix, but... since it is under warranty and they have not updated the belt guard mold since 2009.
Great pictures ... Been there and done that a few years ago ... and I love the comment in the bulletin "This is a cosmetic concern and not an indication of an internal issue"

Both are rather benign bulletins. I can tell you that the crank sensor bulletin was released because dealers were replacing them needlessly based on the new part number being available, and replacing them for unnecessary reasons. That's why the bulletin tells them to use old stock first. Owners are misled thinking, "Something's wrong, I need a new one, aaaaaahhhhhhh!"

Saw it in the auto industry, too.
Yeah you're probably right. I wonder if Harley just went to a new supplier. Not sure why they went with the creme color tho...
