1. when mine starts to get loud, I change it out.

2. Moose has a packing insert that is prewrapped like factory, that's what I use.

THe Moose or Race-Tools 20 dollar repack inserts are handy.
I now use use fiberflass insulation packed as tight as the original, it's just a bit more difficult to do compared to the inserts.

50 to 70 hrs IMO. I like FMF packing because all I run is their mufflers. Only reason I can think of :bonk:

Another vote for moose. The hockey stick is not the easiest to repack so here is a few pointers:

[COLOR=aqua]I used the moose sock type packing not the loose stuff. The "cardboard applicator" that came with the moose stuff did not work with the bend in the silencer inner pipe. So i had some 1/2 inch pvc pipe ~ 15 inches or so long. I pushed that through the sock packing. Then the 1/2 pvc will fit into the end of the inner silencer pipe to give it something to follow through the sock without getting hung up. After the sock is on the inner pipe, I used some masking tape to squeeze the sock packing down a little tighter so it would fit into the silencer body without a hassle. Then as you push this into the body you will have to rotate the (inner pipe with the packing) ~ 90 degrees or so to help the the inner pipe past the bend in the silencer body. Once it is past the bend rotate back until the inner end cap bolt holes line up. Before putting the end caps in place use some RTV silicone sealant on both end caps to keep water out of the silencer. Also make sure to clean the spark arrestor (I used kerosene followed by water). Install the bolts and rivets and your silencer is ready to install![/COLOR]

Moose racing for sure. Easy to install, quiet, lasts a long time and a reasonable price.

Which end of the silencer are you taking apart? It sounds like you may be taking apart the exhaust end. If so, that is why you are having problems getting the packing in. Take apart the intake end next time.

I just re-packed mine today for the first time. Used the FMF stuff. I pulled out a gooey mess, and after the job I'm sure the bike is 20 pounds lighter.....I'm planning on taking her out tomorrow to see if it makes a noticeable difference.

The best packing money can buy is silent sport premium but its not cheap. It does however come with accurate instructions on how to pack your silencer, and it is formed quite fluffy so your packing will way less than any of the others. Packing your silencer correctly makes a fairly big difference to performance.

I've been using McMaster-Carr part number 9356K12 High Temperature Fiberglass Sheeting. For $20 you get a 24x96" sheet....

Just redid my KDX with this.

A) With 800 miles on the first re-pack it didn't need redoing.

:smirk: the piece I used to repack this time was ~8.5"x11". I can get roughly 24 repacks from a sheet...

Now we're talking. A dollar per repack! I love McMaster-Carr.

Their viton o-rings for the expansion chamber are light years better than stock, never leak, and are a fraction of the OEM price.

I use pink insulation from Lowes.... less than 10 dollars gets you enough to repack 3 or 4 times. Works just as good as anything else in my opinion.

x2 pink Panther insulation is where it's at.

I ripped off the paper backing, wrapped some around the pipe, and held the insulation in place with a few masking tape pieces. It only takes a few minutes to do and lasts a long time.

Do you live near me? I'd swap a piece of silencer glass for some o-rings!
