My fan is dead and blowing fuses. I have another fan on order but its not scheduled to ship until the end of the month. I ordered a comfort kit too because I figured if I'm going in there, I might as well add one of those too. With the weather being nice and me being impatient, I'm wondering if there would be any benefit at all to taking the fan out and trying to clean it or anything? Is this even possible? I'm pretty sure its gummed up because I overfilled the oil. I haven't owned this bike a year yet and I'm still not 100% on oil levels and such. Any advise? |

Never had any luck with 2 of mine. Overfilling won't do this. Check PCV grommets and rocker covers for leaks. They'll just take out the new fan. |

If fuses are blowing, this is what you will probably find inside the fan. Cleaning will do no good unless you can replace the commutator and/or brushes.

Thanks for the tips guys. And you don't think this could be caused by overfilling the oil? Some of the stuff I read seemed to indicate that it could cause exactly this. When I took apart my airbox there was plenty of oil in there pooled up at the base of the velocity stack and on and around the PCV valve hoses. |

There's nowhere for the puked oil to go except within the air filter area, unless as mentioned you have a loose hose or grommet from the engine. You have a 2006, which is easier to determine oil level than the newer ones '08-up. With the engine cold, 2.5 qts split between a new filter and a properly drained tank, on the side stand, on my garage floor, puts the level midway between the tip of the stick and the lower end of the XXXXX marks. Hot oil then registers at 2XX from the bottom. |

Do yourself a favor and reroute the breather hoses from the airbox. I'll bet big bucks your intake tract looks like Teeps commutators. Also, do what Danair said, check your rocker box gaskets especially the rear one, that's what took out my fan. (Message edited by someday on October 20, 2012) |

Could someone point me to a walkthrough on re routing the breather hoses? I'm not sure exactly what to search for, so I don't think I'm getting the right results. Do I have to take the entire air box assembly off to check the rocker box gaskets? |

Personally, I would try to fix the fan. What do you have to lose after all? You can usually get a commutator to work again with a mill-bastard file and then the end of a hacksaw blade to clean out the insulated bits. I haven't done this on a fan motor but have used this method on my old sporty's generator. |

Bosgarage, is your check engine light coming on? Mine is. After I shut it down it blows the fan fuse, then next time I turn it on the check engine light is on. I tried to manually spin the fan from the little access hole on the grate and it wont even budge. Must be really gummed up. I attempted to remove it over the weekend, but only got to the point of the rear shock removal when I found out that I didn't have a #40 (I think) Torx bit for the lower shock mount. |

no, it comes on and goes off depending on speed. |

Sounds like a seized bearing. Fuse will go because it is pulling a overload, circuit goes open and the CEL detects this as a fault. Which is all its good for. You may have something stuck in the cowl though as it can happen. |

It all started after riding all weekend in the rain. I guess that could have caused the fan bearing to seize. |

schwiggy I don't think the rain did it I've gone 400 miles in a tropical storm. I re-routed my crankcase breathers a long time ago,I will try to explain. First pull the two hoses out of the base plate,then take some 3/8 hose,(I think thats the size) bend it in a U shape and working from the bottom of the base plate stick them back up thru the holes where you had pulled the originals out of,now your base plate is sealed. Second you should have a hose coming out of each rocker box,connect them with a plastic T and I routed that back past the transmission breather hose and down by the front of the swing arm,cut the end of hose at a 45 degree and done. Thats how bikes and cars used to be,some will say it will suck dirt back in the engine but the pvc valves are 1 way,and my oil analysis has never shown anything wonky PM me if you like I think I have pictures of it |

Regarding a breather re-route option, I did a variation of Ronmold's. I put the breather on top of the catch can after tapping it out to 1/4" NPT. I bought the can on ebay. They are used a lot for go carts. My first arrangement had the hose going out above the rear fender where I had a filter/breather on the end with another line for catching the condensate. It didn't work as well as what I have know and much less mess too. http://www.badweatherbikers.com/buell/messages/142838/626211.html (Message edited by glenn on October 24, 2012) |

Oil on the fan kills it eventually. My fan failed when I had my rear rockerbox gasket start leaking oil. If that's your root cause you have to change the rockerbox gasket also or you will be buying another fan fairly quickly. |

Ok, so I finally got around to replacing the fan yesterday morning. What a pain in the ass it was getting that old fan out of there. The manual just says rotate fan clockwise and remove. If only it were that simple. The picture they had in there also didn't look exactly like what I was looking at. At least installation was pretty painless. Anyway, while I was in there I looked around for any leaks. I couldn't find anything. The fan was very clean, just seized. Changed the oil, dropped a new K&N air filter in to replace the ratty old one that was in there and took it for a pre-"frankenstorm" ride. Everything seemed great. I will have to revisit in a month or so when my comfort kit ships and I'll make sure everything is still clean. |

Too bad you're not local to me. I'd love to get my hooks into that dead fan and see if I could fix it. Or at least find out why it failed. |
