2007 CVO Ultra Classic Stalling Problem

--- Quote from: scottt on December 27, 2019, 03:47:04 PM ---I also owned a 07 CVO ultra. Yes, it was the first year for the 110. While I never experienced your issue I did have some as did other 07 110 owners.
The 07 and 08 110 were known for running extremely hot. My fix was to install a SE tuner, adding more fuel to cool the motor. Could someone have installed an aftermarket tuner that is now acting up?
The other issue was the crankshaft. They were known for being out of spec. I heard of crank sensors failing as well.
I'd have these areas checked, starting with the tuner. Pray it's not the crankshaft.
Finally sold my bike. While I wish you all the best luck, the 2007 CVO Ultra was my greatest problem bike ever.

I appreciate the response. I don't think the bike runs unreasonably hot; at least no hotter than expected for a bike with fairing lowers. 07 and 08 were also the last two years of the old frame and the inefficient "Y-pipe" OEM exhaust headers, which would make anything run hot. The True Dual exhaust this one came with mitigates a lot of that, as it did in my last bike, an 02 Ultra, when I had them installed on it to replace the OEM pipes. I also question whether the crankshaft or crank sensor could be a problem, since the bike runs absolutely flawlessly at speed, and has never given me any trouble other than the stalling issue. I'll ask my mechanic to take a look, but as you say, I hope it's neither of those. Even so, I definitely traded up from my 02 (which had 62K on it when I sold it), so I really can't complain too much.

Start with the basics, clean both battery cable ends and where the neg cable grounds on the frame and if there is more than 1 grounding wire follow it and remove and clean.
Loss of battery power can cause no code setting, though a code for loss of power can be set.
Check each fuse connection, do to age there could be some corrosion in the box, so pull each to inspect.
Disconnect the ECM to inspect the pins, sometimes just unplugging connectors can help a connection problem.
Crankshaft sensor can cause a stall, they are located by the oil filter and maybe over the years it may have been bumped enough times that it is cracked and than temp plays a roll in becoming an open circuit causing a stall.

I appreciate the response. Some of what you suggest has already been checked, starting with all battery connections (the battery itself was new last year). We haven't pulled the ECM itself, and that will be the next step, since your idea [that simply pulling and replacing it can sometimes clear connection issues] is a good one. But overall, the bike seems to run so well, and all the electronics work fine, and it has a new voltage regulator (which it probably didn't need), but it also has a good stater and the charging system seems solid, that I tend to question whether the battery connections could be the issue here. Not that we won't revisit them anyway the next time I bring it in. Better safe than sorry, and an easy thing to recheck.

Did you have another username/account (maybe that's why you can't find it)? Perhaps you posted it on another forum or maybe when you hit the post button for some reason it didn't get posted... you just joined us a few days ago. :nixweiss:

The first thing I did after joining the other day was to search for existing threads about stalling issues on 110 CVO motors. I found one, and replied to it. I may have done it incorrectly as you suggest, since I was unable to find either the thread or my reply to it again. That's why I started my own thread this time. And I got some good responses with new information (thanks everyone!), so I'm hoping one of these suggestions will point to a solution.

P.S. The guys at the dealership I took it to first (where the bike was originally purchased) told me there is no aftermarket tuner, either a Race Tuner, Power Commander, or anything similar, on the bike. Since Rineharts requires some kind of tuning (you can't just bolt them on and expect the bike to run right) and it was that dealership that installed them for the original owner, that's why I expect they simply sold him the download and flashed the ECM with it to adjust the ECM for the pipes (which was one possible solution suggested to me when I had the same exact pipes put on my 02, and I bought the H-D Race Tuner for that bike instead). The bike certainly runs amazingly well, and gets reasonable mileage (typically 35mpg).
J.D.:
These are the most difficult type of issues to diagnose. Seems you first need to tie it back to fuel or electrical. My money would be on electrical, and something happenning associated with elevated heat. That could be a lot of things. I'll assume that there is no correlation to moisture (rain or cleaning/washing). Only thing I can think of is an old fuel injected bike I owned briefly. One of the wires to an injector had a very poor terminal crimp causing the injector to fire intermittently. When it ran it ran perfectly, and when it didn't it would do exactly as you state. It was a bit of a bear to diagnose and really wasn't until it became really bad that the dealer tech could figure it out.
