2009 FXDB: Knocking Under Bike While Coming To A Stop
Going to have the bike looked at by the dealer Saturday already since I am still under warranty, but I thought I might ask for some insight anyway.
The issue I have, is when coming to a stop, there is a knocking that is not audible, but I can feel it most noticeably being transferred to my left foot peg (I have mid controls). It feels like it is either coming from the priimary, or the transmission. It doesn't matter whether I am using the front or back brake, so I eliminated that from possible causes. What I did notice however, is that if I come to a stop while in neutral, no issue, in first gear, or second gear (with the clutch in), no issue, but if I am in 3rd, or in 4th when I start stopping, and I have the clutch pulled in, that is when I feel it. Almost feels like the kickstand banging up against the bottom of the primary, but I wrapped it in cloth, and I know it is not that. Feels internal though. Any thoughts?

yes. I'd be willing to bet it's the automatic primary chain tensioner.
it's trying to find the next step.
there is an HD tech tip about this. It basically tells you to go out, do a few drag race launches and it should seat itself to the next notch.
Just ride it.

I forgot to mention, it happens mostly while on bumpy pavement, and I do notice it a bit while riding, but due to normal engine vibration, I think I mostly notice it when coming to a stop. So pretty much that sounds like the automatic primary chain tensioner? Shouldn't there be a better way to adjust it than beating the hell out of the bike? I should suspect best to let the dealer look at it, but definitely thanks for the suggestion, I will pass ti on when I drop the bike off...

Mine does it occasionally, and does it more often when 2-up riding. I attributed it to motor mounts but not sure.
I drag race enough when out with the boys so I haven't had any luck with that tech tip unfortunately.

Issue resolved by the dealer on Saturday They actually noticed the issue right away and noticed that my engine was alot closer to the lower frame than that of a new bike. Turned out to be a bad engine mount up front that was replaced under warranty and issue seems to be gone now...
