Cynic: There are 4 bellville or disc washers in there. They are not wave washers as some have mentioned.
Going from the rotor, the first one is cupped outward. The second is cupped inward. The third is cupped outward and the last one against the cam is cupped inward. This is called series stacking and basically the pressure is what one spring washer would take to compress, but it gives more travel in compression by doing this, or stroke.Pissed me off, no such size of these things in any books at work. They are a Harley custom manufacture. Now on to plan (b).

RE: Compensator
fj4069: There's your answer asto why some are quiet and some drive you nuts. They will all fail eventually as these springs have only so many cycles in them before they flatten. Some may be heat treated more and produce a higher working pressure and will live longer. The spring pack can be easily changed, but my problem at the moment is finding a suitable replacement without having to get them custom made. Still working on that. Here's my scoop after carefull examination of the whole mess.
(1) The spring pack is way too weak for the 96 and up engines, and is the sole problem with the comp design.
(2) The cam travel is twice what it should be, which can be changed with the correct disc washers in thickness, stacking methods or amounts.
(3 )In all but idling and light cruise loads the cam reaches it's travel limit and becomes in effect solid or actually worse with it just pounding slightly off the limit and this to me is worse than no comp at all as it produces an impact on the crank and drive train.
(4) Knocking sound, even with tight comp assemlby is cause from the cam tip coming off the flat section of the ramp which is fairlylong running into the ramp. There is not enough spring pressure forcing the cam to flat spot, or resting point to create enough friction so it basically gets a run at the ramp and hits it instead of being at the start of the ramp and going up gently. On mine there is only .030 wear allowance before that tip pressure will no longer be possible. Mind you these components are really hard and that could take 50 years to happen.
(5) Although a good working comp has benifits, if the ids ever happens for the softails it's going in the garbage as the ids will protect the system well enough to go solid on the engine.
(6 )Wear marks from the cam in the sprocket show evidence of the starter clunk as the wear is barely noticable but of equal bottoming out length to the load side but the opposite ramps.

RE: Compensator
What can I say? He needs tobe taken out to the back room andeducated. The springs are in the altenator rotor, in the small can that sticks out. If you went solid with yours you should flatten the 3 dimples in this housing and remove the discs. Otherwise they will rattle around in there and could become a problem down the road.

that would explain the primary noise on my 06. when i pulled mine apart to inspect the knocking noise (hd told me it was operating within manufacterers tolerances) all the coned/cupped washers were flat washers. fugured that was the issue and just put it all back together. mabey i'll rip it back apart and just buy the new one ( or just add some shims and mak it a solid deal) and just chuck the old one through the show room window.
