allow you to "shut down" the rear cylinder if you roll the throttle forward at an idle.

Only on Touring bikes.

Wife's cramkshaft position sensor

My wife is cramky no matter what position she is in and never displays an error code. Should I call HD?

This is were it gets sticky even to the dealer. The CPS is just a small coil that the slotted breaks on the crank generates a small current to the ECM. The missing tooth tells the ECM were TopDeadCenter is for timing. If the CPS is totally bad ECM will shut off Fuel Pump. However if it has a problem it could just miss a few counts and the ECM loose a few counts and the timing get off bad enough that engine would not idle. My thought would be that the ECM should know how many counts there should always be between the missing one and at least throw a code and fail safe (no idle but at least run). Maybe it does not. As simple is the CPS is (coil of fine wire) my thought is the connection for it is bad. It is a cheap part. If all the simple fixes do not work, I sure would replace it to see if problem goes away. interesting someone even thru out Speed sensor in transmission. Surprised that would affect idle or running

That's what I thought Dickey, thanks.
I will check out the other suggestions, it did seem like maybe it was choking on one cylinder. But like I said, it shouldn't be my problem, welcome to the wide wide world of HD quirks and problems Blackfly, lol.

Wow that's interesting- I'll have to at least look at the transmission plug too after reading that. So the speed sensor affects the A/F mixture also ?

I'd probably rule out anything to do with the sensors monitoring that... Unless it feels wrong. by that I mean: when it running this way, does the motor feel like it's running a 1000rpm but indicate 2000rpm?

never noticed any errors with the tach, it seems fine and accurate.

So I pulled this up because I just wanted to say that Harley did the right thing in the end and replaced my bike. ( With a 2013 ). I also should say that although it was a process for sure, everybody I dealt with was very nice. I had brought it to Danbury HD for the same problem and when they couldn't fix it without replacing things (guessing) I met with a company rep. who was patient and thorough in getting the whole story.
I look forward to many miles of trouble free riding.
P.S. I for one don't blame any of this on the techs who did the engine work.
the problem with the ECM or wiring or whatever probably was there when the bike was built ...... on a friday afternoon ?
