I have a 2008 XB12S. I just bought it a few weeks ago. At around 850 miles, the engine light came on. It didn't run any different. Since i was due for the initial servicing, I took it in to the dealer. They said it was the exhaust valve actuator. I was just curious if this is a common problem. I already plan on changing the can to a drummer, so I'm not terribly concerned about it. | ||

That seems to happen to me if I try to start the bike while the cooling fan is still running. I don't know why, but I just clear the error code and everything is fine again... | ||

I had that problem for the first few thousand miles of ownership of my '06 Uly. The engine light would come on suddenly, often when first starting the bike... the actuator fuse would be blown - so I carried fuses. Then I realized my actuator wasn't really working very well so I worked it back and forth by tugging on the cable. I now conclude that the bike had been sitting so long on the Dealer floor that maybe a little corrosion set in, perhaps? Anyway working the actuator was enough to free it up and I haven't blown fuses nor engine light since. | ||

I will try to lube the cable. The valve is stuck in the open position, so it is really only affecting the low rpm power. Not a big deal. Thanks Growl and Jaimec | ||

Sticky cable would explain your problem. Mine is still a mystery... :-\ | ||

It might not just be the cable, work the valve itself, open and closed - full range - a number of times to free it up. | ||

Mine if having the problem now and I'm waiting for a part from Harley under warranty. This part goes into the air cleaner as part of the puzzle. I don't get it, but we'll see if it does the trick. The whole thing had the Techs at the shop baffled and they had to give Harley the computer reading and wait for them to come up with a answer. The part will be here in a week so we'll see. | ||

Snapping the throttle to wide open wouldn't cause it to open further than it normally would? I have a tendency to go wide open when changing lanes, or passing cars so they hear me coming. I don't like to be next to cars for very long if I can help it. I'm very paranoid of other drivers. | ||

No. Your throttle isn't directly controlled to the exhaust valve. That is controlled by a computer that opens it based on engine load and rpm according to a preset program. | ||

It's not a graduated thing, either. The valve is either wide open or fully shut - one exhaust track or the other. (Message edited by growl on May 23, 2008) | ||

I think a switch on the handle bars to trigger the exhaust actuator would be very cool... I'd rig one up except I don't want to risk frying the ECM. Someone suggested a diode could be used to protect the ECM so if you are electronics savvy and can suggest which diode and how to wire it you would be my hero for a whole week. I could totally dig actuating the exhaust valve when passing by the local biker bar or when passing up friends on our organized dual sport rides. |
