Well, my bike has started hiccuping/missing slightly again. I opened the airbox yesterday, and noticed that there were "wet" areas on the plastic. Seemed like the texture was almost like fuel, might have been oil from the bypasses, though it was not very slick. Is this normal? Am I just being paranoid, and the bike runs like this with the racekit on it? The hiccups/misses happen alot within the the first 5-10 minutes of riding after starting it up. Once warm, its only occasionaly when cruising along it will hiccup a little, like one of the cylinders didnt fire. Also, it usually dies atleast once 10-15 seconds after starting it up, while im letting it warm up a little. What are some other things I can take a quick look at on the bike to see what might be causing the problems? |

I've got three ideas. First, I wouldn't be too worried about the wet air box. There are several reasons why this could happen, though none of them are truly serious, unless there is A LOT of oil or fuel. I'd check your plugs. I made the stupid mistake of starting my bike this winter. Bingo! Instant fouling. After changing the plugs, my Buell fires like a champ and never misses. Second, and more involved, you could always adjust your cold enrichment with ECMspy. Doing a search here for plugs will net you tons of info. Same situation for a search of ECMspy. Hope it helps. |

Check intake tract for air leaks between throttle and cylinder heads. Run bike at fast idle, around 2,000 rpm, and spray contact cleaner or WD-40 all around each intake manifold to cylinder head seal. If the engine speed changes noticeably, you've found an intake air leak.
Be careful that when you are doing this investigation that you don't get any spray into the airbox or normal air intake as that will produce a false indication.
You can even use a spray bottle of water for the test fluid.
Good luck. |

Next idea to the problem is...if you have an aftermarket exhaust and the weather is still slightly cool, it takes a little longer for the bike to warm up to a normal running temp. The deal with aftermarket exhausts is that they release the hot gases much quicker than he stock exhaust, hence the hard starts and even stalling engine after a few seconds of it running in the morning or when ever started cold. The stock back pressured hot exhaust actually helps the bike warm up the way you would expect.
What I mentioned above was told to me by a Race Buell Mech. My bike does the exact same thing. As my engine gets warmer it run better..same with my lawn mower, weed eater, etc. The quick sputter now and then is completely normal for your Harley Engine..thats what they do.
The liquid you are finding in your air box is also normal. Sometimes it looks and smells like gas and sometimes oil. I have a catch can and I have both when I drain it.
Its all normal from what I have been told, but then again maybe the shop just wanted to get rid of me and all my questions...lol |

Well, I changed out the oil yesterday, along with the primary case fluid, and washed her. She is running better after the fluid changes. Idle didnt drop at all after turning her over, and felt super smooth through all the RPMs. |

and if you want to get rid of that oily film in the airbox, get a catch can kit. |

Thanks for the tip! I was looking at getting one of them, but they are kinda pricey =\ |

Definitely do the catch can, or at least a reroute with a filter on the end. Mine "hiccuped" like crazy before rerouting the crank case vents out of the airbox. After the reroute, it's hiccuped maybe 3 times over the past year. It'll also eliminate the gunk from forming inside your air filter, guaranteed.

Thanks for the tips guys! I also know I need a new battery. She would barely turn over this morning, had only been sitting since Saturday. Anybody know if the battery would be covered under the extended warranty you can get through the dealerships? |
