06 CVO Ultra issue

Hey all, I haven't posted in a while.
Just thought I'd through this out there to see if anyone has any thoughts as to what could be wrong.

Ridin home on my 06 SE Ultra Classic, I noticed that the bike was making some new noises. Sounded like the pinging from low octane fuel to me, but I always run premium and even though there was that ocasional noise it still ran great.
Well, I just get over a mountain pass and come to a stop at an intersection. I go to take off and it starts popping out the exhaust, sort of like a back fire but not as loud. Luckily I was only a mile or so from my house, but all the way there I had to feather the throtle and clutch to make it.

Later when it was cooled off, I pulled the plugs and found the front one to be black and wet with fuel. The rear one was dry and white-ish.

Been going through my head as to what could be causing this, since the shop isn't open for a few days.

The bike has an HD race tuner, and SE muffs - thats about it as far as mods.

Right now I am thinking the ECM may have gone bad? I don't know at this point.

I did just get back from riding it all the way up from SoCal to Montana and back which where I ran into a lot of cold (snow) weather, but it ran like a top the whole trip with not even a thought of something maybe wrong with my bike. But yesterday I went to the Palm Springs bike rally, and most of the day was a 105 degree day. On the way home from that is where this trouble started.

Thoughts anyone?

I'd try new plugs before i did anything else, you can get them at any auto parts store, may not be what you want but will be new and cheaper than the H-D store just to try them out. I'd get Champions, all though I am running NGK's in my bike right now.

Plugs would be a good start. Sounds like your over fueling the one cylinder. Maybe a bad injector (stuck open) or dirty.

You definatly need to change the plugs and may also need new plug wires. Make sure the connection at the top of the plug is tight. The last place I'd expect the problem is the ECM. Coil breakdown is far more common.

I hear ya bout the bad gas idea.
But I filled up almost a hundred miles before this happened, while riding in 100 degree heat and going up and down mountain passes with a passenger.
I've been there when I've been unlucky enough to get a load of garbage fuel, and I would notice it pretty darn quick. So I can pretty confidently say it's not fuel grade related.
A buddy of mine showed me how to get error codes off the odometer, and there were a couple. I'm no late model HD mechanic, so it's at the shop right now.
From my description to the ticket taker at the service desk, he said it sounds almost like a stuck/faulty injector. That's the last I've heard so far, since I've been busy with other stuff. Plus I told the shop that I'm in no hury to get it diagnosed and repaired, since they were pretty loaded up on the service sheet.

I will let y'all know what the final fix was.

Well... It's been a sad day indeed.
Got word from the shop, and it's not good.

Apparently one of the cam bearings spun inside the case and pretty much trashed the case. There is metal shavings through out the motor, and the shop is saying minimum of 5k worth of parts and labor.

The shop is calling Harley to see if they can do something, since this is not a case of abuse or oil starvation. Harley offers rebuilding of their standard motors, but not on their CVO 103 motor and that's what the shop is going to see about. They are hoping that since it's only a 2006, and it is a screaming eagle ultra classic. That Harley may take interest in seeing what happened, but I can only hope and pray at this point.

Being that I am unemployed, pretty much any big ticket repair is too much for me. If HD doesn't offer to do some thing to ease the pain of repair, then I am just going to be forced to put the scoot in deep storage untill I get back on my feet financially.

I'll keep you all posted on what the outcome will be.

That is a real bummer, hope H-D does something for you.

UPDATE:

Harley is sending an entirely new engine to replace the broken one - FREE!

WOW… that is great news,
I had GM do that once for me with a 6.5 turbo diesel,
Did you have to get huffy with them? Just like a new bike now.

Surprised, but happy for you I think you should buy a lotto ticket today cause that's pretty lucky!
The MOCO isn't known for free motors especially for one out of warranty.

I don't know the details yet as to what it took to get HD to send the new mil, but I am not complaining since I am just going to have to cover the labor costs in getting the equipment replaced by the dealer.

The phone call was quick from the dealer, he just said no more worries HD is sending you a new motor. When I get to the dealer in a few days, I will see about what they had to say/do to get HD to cough up a new replacement.

As for me, I didn't have to flame HD at all. I was waiting for the dealer to get back to me on their result of dealing with HD, and if they were going to tell me that I was going to be SOL. Then yes, I was prepared to raise hell with HD. But forunately it looks like I won't have to do that now.
