I know there have been problems with the Comp nut coming loose on some of the 04's and 05's, but I've only heard of one coming loose on an '06, and none so far on the '07's. As some of you know, I had a problem in MV with my bike after the HD dealer did the 5K service...they had tried to adjust my auto chain tensioner and screwed it up in the process. It was making a rattling/scraping noise on the primary side, then it quit on the way home. I pulled the primary, took the adjuster out and re-installed...no more problems, and I've put over 1K miles on it since. Weelllllllll...after installing the RH's and getting the dyno tune yesterday...guess what? Went for a ride this afternoon, and on the way back felt a clunk under my left foot (Diva felt it too), then at idle, there was a distinct metal to metal sound coming from the front primary side of the motor. Did not hear it yesterday on the way back home from the tuner...thought I heard something when I cranked it this morning, but then nothing. After feeling the clunk under my foot when gently rolling on/off the throttle on the way home this afternoon, pulled into the driveway, and there was a distinct rattle in the left primary, but only at idle or when shutting down or starting...at RPM above idle, no noise. This noise is NOTHING like the noise in MV and does not sound like it's coming from exactly the same place. The rattle in this case is more of a noise like a metal to metal thing, but not AGAINST the primary, like when the adjuster was out of whack. Having seen the Comp nut and sprocket, and where it's located, the noise is definitely coming from there.
I checked the comp nut when I was in there before, but of course, did not have a socket large enough to put a torque wrench on it, so didn't get to check the torque. Is it possible that doing the dyno run stressed things enough to make a problem that was going to happen anyway show up?
Took the bike to the dealer, dropped it off. The service writer seemed to agree with my diagnosis....comp nut. Left it for them to get to tomorrow...I hope.
Comments? Anyone else had this problem?
