Got off of work tonight...(work nights) and started the bike to warm it up before I left. Running wierd...hmmm holy shit it's running on 1 cylinder.. (2008 xt 1700miles) I noticed a lot of dew covering the bike but I've ridden in downpours before...it was chilly...probably high 40s...coldest it's been in....I have to call harley in the morning... Anybody have this issue? exhaust is wired open..maybe this is a cause..I have a right side airscoop and aprilia mirros...maybe these did it? Thanks | ||

You may have a loose spark plug wire that condensation got into. -=shrugs=- Running on one cylinder in cool weather is either an indication of the engine *thinking* it's overheating (CHT sensor/ECM problem) or you've lost fuel/spark to that cylinder for some reason. Ulysses have experienced a rash of loose spark plug wires and that's relatively simple to check, so I'd suggest popping them both off and making sure they're seated well, sealing well, and free of corrosion. | ||

Coming down from time trials on Pikes Peak this summer, I experienced the same thing. It was confusing considering I was just at 14,000 ft so I thought electronic or misread sensors. Turned out to be a wire that chaffed while riding up & back to watch the racers prepare for the pending race. | ||

Just woke up an hour ago and tried to troubleshoot on my own before I call H-D. (cuz I know it's gonna be a long wait) Well, the forward cylinder is not running. I confirmed that there is spark getting to the plug and the plug was indeed wet. Why it's not running I have no idea...btw those plugs are a pain to get to. Gonna have to call H-D today. | ||

The front plug is easy with a 5/8" box wrench. Weird, fuel and spark are getting to the cylinder and it won't run... | ||

Sounds like a fouled plug to me. Replace it, and see if the engine starts running on both cylinders again. | ||

There was spark at the plug as well...plug is working as it should...There was fuel evident on the plug...maybe not enough fuel or what is getting to it... Called harley...Friday is the earliest they can get it in to "look" at it...I've read stories of guys bringing in their bikes for warranty work and a month later still no bike... | ||

Spark, fuel - but in adequate amounts, and at the right time, and with the plug installed? Is the wire chaffed anywhere that might be leaking current when installed? I'd give your dealer a try before getting all sensitive to how long they will have the bike. ....I've heard stories about dealers driving an hour on a moments notice to pick up a bike broke down on the road only to find the bike was merely out of gas. I would bet your situation is somewhere in between these two extremes. ~jammer | ||

I have read somewhere else on here that someone was having an issue, his plug was partly fouled. The plug would spark when not in the bike, but when inserted it would not fire. I believe he replaced the plugs. Did you try the self cleaning plug trick? | ||

Just because it is showing spark when not in the cylinder doesn't mean it is good as Froggy said. It can have a weak spark (may look OK), but not be strong enough under compression. Same thing can happen with bad wires or a bad coil. I'm not saying that the plug isn't good as it may be. Just saying don't assume it is good just because it is showing spark outside of the cylinder (if that is what you did). I would put a plug in it and try it before taking it back. Unless it is easy for you to get it back to the dealer. (Message edited by dentguy on September 16, 2008) | ||

$50 bucks says it a fouled plug Uly don't like to have the throttle twisted until they are warm. Good Luck | ||

I had that happen several times on my Lightning. Usually when I would fire it up to move it at work, and then shut it down after a few seconds. Like Froggy said, did you try revving the snot out of it? If it is a little wet, that could be it. Rob |
