Hello, I'm new to this site and new to motorcycles as well. I've only had my bike for about a month and a half. 3600 miles on it originally, and it started making a knocking sound. As i'm new to the whole scene i can't seem to tell where the noise is coming from or what is making the noise. I know that it could be a ton of different things, but any help would be greatly appreciated. I just changed the oil and checked the primary chain and all is good. All dealers are backed up like a week or 2. Thanks again for any help or responses. |

If possible, record a video of it and post it to youtube, then link it here. These bikes are very noisy by nature, but if you take a video of the bike idling while you walk around it (hold the camera in different spots on both sides of the motor), we *may* be able to recognize some noises.
2004 XB12 with only 3600 miles? When was the last time the fluids were changed, and what fluids were used? |

I appreciate the response, i am uploading a video now. Seems as though it is taking FOREVER! When it finishes i will be sure to share the video.
Fluids were just changed and chain was checked as well. mobile 1 20-50. |

Could it be the front engine primary Sprocket lose...Some have had this problem...
When you start to drive away with in gear small load on the motor does the sound change at all??. |

Hey Chris,
I think Hogs nailed it, loose front sprocket.
There's an old service bulletin concerning that.
It'll just cost you a primary gasket and an hour or so. Well and a chunk of aluminum to act as the locking link. Or purchase one from American Sport Bike. |

The Harley Shop might do it for you, not sure. |

Thank all of you for the answers and help. I'm hoping y'all are right. I'll try and get a gasket tomorrow and try to find somebody that has a big enough torque wrench. I hoped I could ride it a year or two before something big needed to be done. We'll see and I'll surely update you. What's the torque spec again for that nut? Wow! I'm not sure I'm big enough to put that kinda force down even with a cheater. Thanks again and looking forward to learning more about the bike and riding.

Updated specs. 240-260 pounds.. call it a good 250 and you are good to go !
Be sure to follow the manual for lock tight goo I believe its the Red Check on that...
Clean the treads of any old Goo to on the sprocket Shaft.
That chart that Blake posted tells it all...

I had this happen on my M2. The easy way to tell this is the case is to start it, put it in gear with the clutch in, and slowly let the clutch out. Not enough to move the bike forward, just enough that the idle starts to drop (and your idle sounds like it is set a bit low).
If it is a loose crank nut on the stator bell, the sound will stop when the clutch is lightly engaged, even when the bike is not moving (or barely moving). |

well it definitely stops before it dies under load. unfortunately nobody around here has a primary cover gasket. harley can't get one. made a few calls to see if anybody else can get one, but haven't heard back. I need to talk with somebody who has done this cover removal if possible. I have a few questions about the process. Please pm me or whatever it takes. thanks |

Lone Star Harley/Buell in Tyler can get the gasket for you. Or American Sport Bike will send it straight to your home.
It's not a big deal, just an hour or so.
I don't have that big of a torque wrench either. Right length wrench/cheater bar for your weight will work.
250 LB*FT/(your weight) = Load Point Distance
Exame:
250 LB*FT/180 LB = 1.39 FT (16-11/16" or 42.3 cm)
That is valid if the wrench is horizontal. |

Thats crazy... I have on many times just reuse the gasket..Take the primary cover off easy,evenly and If ya do without tearing it ..Just clean off well both sides spray of brake clean whatever to clean dry... and put a " THIN " coat of gasket maker of just about any type,I use 3M just enough to wet both sides and reinstall...
Has worked for me many times.... |

well if i had the tools with me i wouldn't hesitate to do it that way. but i don't have a torque wrench capable or that little locking tool. for it to be such a simple thing, i seem to be having a hard time on it. lol everybody that i've called still hasn't called me back. guess their having a hard time with the idea as well. |

You can easily kludge together a locking tool from soft scrap metal of some kind.
The newer XB gaskets can often be reused. Not a big deal to gamble, as if you reuse the gasket and it does leak, you don't have to rotate the engine again or anything, you just pull the cover again.
You could use the old gasket with a thin layer of permetex grey (or other form-a-gasket stuff) on both surfaces, that will keep all the spacings right and won't leak. |

well, ding ding ding! y'all were right! primary drive nut was loose as a goose. thank you again bill for the talk, and information. learn something new every day. I appreciate it again. I haven't completed the job yet. I ran out of day light hours and found out i should have bought the 1/2 drive torque wrench so now i have to swap it out tomorrow and get after it again tomorrow. but all in all i'm happy i started the job. saved some money, learned about the bike, and got to spend some time with it! lol thank you all and i'll update when finished. |

Excellent! I wondered if that 3/8 drive wrench was going to make it that high without breaking something.
Find a fat guy to stand on a 12" breaker bar.

Just curious how many miles on this bike?
Got a 2004 here as well as a 2005 with over 40,000 on them and never a problem with them YET  |

It usually happens after you replace a stator or have the stator bell off for some other reason. The torque spec in the earlier service manuals was too low, so you get burned by following the manual. They issued a bulletin correcting it later, but that doesn't help you if you don't know about it. |

There was 3600 miles on it. Evidently it didn't get re-torqued when the problem was found back in the day. Also there was not a lick of thread lock on mine when i pulled it off. I had a brain fart while in the midst of this issue. the guy gave me a 250 inch lbs torque wrench and i just saw (250) and assumed he gave me what i asked for. So i did the same as bill and used a breaker bar and put all the torque i could on it possible with red thread locker as well. Rode it to work tonight, and all is well. Need just a small adjustment on the shift linkage and throttle and we'll be good to go... best of all i only busted two knuckles through the whole deal. now i can set my eyes back on the dean headers  |
