When to repack you cans?

Wondering if there is a guide or whatever to when you need to repack your cans. I have about 15000km on the Muzzy's right now and they just seem to be getting louder. I'm thinking it's time to repack but what have others experiences been?

That's about right just did my buddies Muzzy damn that thing got very tinny sounding so we opened it up most of the packing gone.....time to re-pack, and use scotch tape to hold the packing together burns off quite quickly....
Thanks for the scotch tape trick. I heard string in one post but that would be a pain in the ass. I've never repacked before, it the stuff specific for each type of can or cut to fit? How tight to pack? And is there a best packing material?
I was asking some people about this and they said not to worry.

However, if my muzzy muffler starts sounding tinny I would definitely like to repack it.

more info please

Naw it's not bike specific, the packing material he bought is off the Muzzy website "more money than brains" but I recommend the one peice sheet as opposed to the loose stuff, sorta looks like a house insulation just not as thick, can prolly get it at most bike shops. Ya have to cut to fit, just make sure its long enough for the length of the can. As for brands it doesn't matter...
There's better stuff out there now. The local shops sell Yosh "pillows" of repacking matierial. I redid my own Muzzy's even through they were close to new. There isn't much material in the stock Muzzy's to start with and that's where a lot of the noise comes from.

Flow, you've got the twin Muzzy's so you'll need to buy 3 pillows of this new material. What I did with my cans was remove the back end (screws) and ram pack the remaining glass to the forward end. Don't pack it solid but do pack it so it's about the firmness of medium foam rubber. Then cut open the pillows of Yosh repacking and feed and tamp in one and a half packs per can. Pack it tight enough that it feels like a medium foam rubber again. You want it firm but not solid. This may mean that you can't fit in the whole pack and a half of new wool but match the foamy feeling rather than ramming it in too hard. If there's some left over so be it. Be sure that you have the last of it sticking up a bit so as you replace the end cap there's some packing filling the cap hollow.

the Yosh pillows are great stuff. all the packing is contained in a heat resistant case. wrap it around then secure it tight with string then put the muffler back together. muuuuuuuch easier then dealing with glass wrap or what have you. they last a really long time also. i have about 16,000k on mine and just had it apart to shorten my can and it wasn't hardly even blackened. the Yosh pillows also keep the can alot cooler. i can go for a spirited ride and stop and i can put my hand on my can and it hot but not burning hot. apparently that's how you can tell the Yosh stuff is finished. when the can gets burning hot.
This makes me feel like a total noob...I didn't know you could do that.

What'a newb......:evilgrin
Does that material apply for all bikes twins included?

Some friends noticed the streaker is louder than before.
My question is.. the tinny sound can be corrected but what about just loud throaty low sound. I like the throaty rumble, but the "crack" is what ppl are complaining about.

Does repacking fix this?

Yep.

too much work. I like to buy local if I can and satisfy my instant gratification kick.
Imperial also carries them as do a lot of other shops I'm sure. Yosh is a popular brand.

If they don't have them then they can certainly order them in.
