I'll try to get a video up latter today, but this can't be good. Sounds like it's coming from the top of the engine. I did change the timing tables to have 5 degrees at idle. I think i'll change it back and see if it makes a difference. |

Thanks! I'm going to reload the maps with no timing at idle like stock. I swear the engine didn't sound this loud at idle until I started F'ing with it. It stops once it's warmed up, but when it's cold there is a distinctive thund, thund, thund. I will make a video tomorrow and post it. |

Note the numbers titled "spark advance." Start the bike cold and watch those numbers. Tell us what they do... That will answer your question. I really don't think the bike will need any advance at idle. If you're accelerating from a stop you have already reved the motor up to 12-1500 before letting out the clutch. What numbers have you used for your square idle experiments? Do you have an xb9 or 12? |

I have a 9. I think my square idle numbers were 65 front and 58 rear. If I can find a auto parts store that will lend me a 260lb torque wrench, then i'm going to retorque the compensator nut with some red loctite. I've read on here that it will knock at idle when loose or does it always knock? I know it didn't make this noise before and it sounds like it's coming directly from the cylinders. The timing advance was 5 degrees in those boxes last time I had it hooked up, which is exactly what I put in the timing tables. I'm pretty sure it shows zero though until it goes into closed loop.

Does anyone have the dimensions for that special tool (metal bar) that keeps the sprockets from turning? |

Moose I just cut one of those! I think somebody said 4.25" clarified with "about". Worked for me. |

Well here's a video after the bike warmed up some, still waiting for youtube to clear the cold idle video. I think it's just the push rods making noise, but it's louder now than when I first got it. I'll retorque that sprocket nut just in case. warm idle, not completely warm though. http://www.youtube.com/watch?v=uEvczmLregk cold idle http://www.youtube.com/watch?v=AZVyusWqNBQ (Message edited by moosestang on October 12, 2008) (Message edited by moosestang on October 12, 2008) |

thats sounds like a lifter bleeding down when your not using it the slap ends up comming from play at the end of the pushrods. and after a little while the thing probably pumps up. |

I'm green when it comes to push rod motors, so that is all greek to me. I'm going to beat on it tomorrow and see if it gets worse or better. |

Just wanted to post an update. I changed my oil and oil filter and the noise is completely gone. I previously changed to mobile 1 v-twin and decided to try a conventional 20w50 to see if it made less noise and it did! I also changed from a pure one oil filter to the napa gold 1394. I can't believe that the mobil 1 would cause the noise heard in my video. It tests as a very high 50 weight and shouldn't shear as much as a conventional. It's possible the pure one filter was to blame. I'm going to have to try the mobile 1 again to rule out the filter. |
