250-500cc 2009 WR 300 silencer repack

Followed the instructions in the manual for the repack, by the instructions the tube with the holes in it that the packing goes around should come out. Well needless to say I can't get it out! It kinda looks like the rivets at the other end of the canister need to come out. Is this what needs to happen or am I doing something wrong? I guess I could try and slide the new packing in around the tube. I've repacked fmf spark arrestor silencers before and the tube came out when I pulled it apart. This is the stock WR silencer though. Any info greatly appreciated.

Those 4 rivets need to be removed as they secure the core to the canister. I replaced the rivets with some button head screws for future ease of use. You do not need to remove the 4 button head screws at the end of the canister holding the end cap on.

I was not able to get the o-ring back onto the end of the core, so I omitted it and no leaks. You may have better luck.

I ripped into my 300 stock silencer today and was pleasantly surprised that the packing wasn't that saturated with oil at 14 hours. I know I was jetted a bit fat during the first few hours while tracking down Mikuni jets. Any recommendation on packing material? It's kind of an odd size (about 10"x19"). I was looking at the Moose offering here, but it's a bit short.

PC, I know you're not running the stock silencer any longer, but I managed to get that o-ring back on the inlet using some patience, silicone spray lube and a putty knife. I ended up replacing the rivets I drilled out with new rivets.

I got my o-ring to go back in too, but it wasn't easy! I used FMF 2-stroke packing when I put mine back together. I drilled the rivets out and replaced them too. I wish there were bolts holding that core in.

I might try to replace the rivots with little screws. we'll see how it works. OTOH, those screws are always a bit of a pain to get back in on other mufflers.

i tested at 94db at china hat, which is the LOI limit for the isde qualifier, so i'll probably repack shortly before idaho city, just to be on the safe side.

I did my'n at 105 hrs, was hardy saturated either, running 25cc of oil to 1 lire of fuel

and near perfect jetting, ill post them up when i find out where i left the notes

Wish i'd taken a picture there was hardly any on it?
