BEST solution - loose comp nut/'08 107"?

Hey guys - since my 107" build I have what sounds like a loosened comp nut. There's been plenty written on how-to on a loose comp nut, so that's not my question. Is there a hands down best way to solve for this?

Is it to remove, clean, re-torque and red locktite? Is it drill and stake the nut to the washer? Or spend $44 on what seems like a permanent fix like this from AMS?:

Thanks for opinions, I want to open this up and get it fixed before next weekend.

I ordered an AMS lock. Will report back on install if anyone's interested. Thinking I won't use any locktite as I can change it easier if I need to in the future.

Your 08 should have a bolt, not a nut

Yes - it's a bolt - you're right. There's a new washer/spacer in the lock plate kit that's threaded. The plate fits over the torqued bolt head and holes are irregulary spaced as to line up w/the new spacer. Couple of cap screws hold it together...may throw some LT Blue on those.

Something isn't right. You shouldn't need that thing and you are guessing it's a comp bolt coming loose. Putting the cart way before the horse here.

What comp do you have? Stock? SE? If it's the SE its THAT POS making the noise... throw it in the trash.

Best best practice is to buy a NEW comp bolt every time you loosen it. That's what the SM states. If there is a question... follow that, I guess.

There are numerous things that can give you that kinda noise. clutch hub bearing, for example... or the comp being wore out and it's bottoming really quick.

Oh... one thing that I found on my bike was left over locktight in the bolt hole itself will not allow the bolt to fully seat. Used a dentist pick to dig that all out and bought a NEW bolt, instead of locktiting old bolt.

Hi Truk - I have the stock compensator, not the SE. I'm guessing it's the comp - the noise is on the left and I especially hear when decel at lower speeds and going along in a lugging mode (like 4th gear, 25-30mph). It sounds like 'slack' for lack of a better term. It has gotten progressively worse in say a few hundred miles and I assumed (I know, I know) it was the comp that was making noise. The bike has 7500 miles and only 600 mi or so on the 107 build. I figured I'd crank it back down and got on this locking plate for $50 to my door (which arrived today). I ordered it because I don't want to have to F with it again...figuring that it wasn't big bucks for piece of mind (if it's this at all).

I have to make a locking tool out of some 1" stock and hope to change it tomorrow. We'll see - one question - are the threads on this bolt left-hand? So I should go to the MoCo and buy a new bolt hunh?

thanks!

This is the installed AMS compensator bolt lock.

I didn't notice it before looking at the pics, but does the comp sprocket look like it's fracturing/splitting at 10-11 o'clock?

I sure would love to look at that comp alittle closer without the chain to see what is up with that possible fracture... That looks like a good fix except for the sprocket... In spite of what some one else says, the SE compensator is way better, ask the dealer to show u both together, then u will see how much better the design is vs the stock one u have. Replace with SE comp and u will be done, period.

That looks like it will hold.

Pete... better do some searches here and on HTT before you make such a statement. We don't care what the 'dealer' can show you... I have personally thrown TWO of them in the trash, and so have a LOT of members. http://harleytechtalk.org/htt/index....c,29069.0.html

They DO seem to be a bit better lately, though. I will get another one because the DO work... just hate the self destruct mode.

Just went for a maiden voyage of 5 miles to test it. For the sound/clunk I was hearing, the retorque seemed to fix it. The hat should keep the bolt in place and if the sprocket doesn't self-destruct I should be all set.

thanks for all info -
