Repacking muffler

[tnarg]

Being that 4stroke noise is a big issue I think its time for my muffler to get a repack. Whats the best option? Want something that will get the noise back to what it was and something that will last more than 2 seconds. Cheers for any advice.

Have you heard of people using steel wool? Like those sponges.

It works well on 2 strokes such as pocket bikes as normal packing just gets soaked in oil.

I know that theres no oil in 4stroke exhaust but theres still the carbon build up.

Your local bike shop will have what your after,repacked both cans awhile back on the TL,cost was roughly $30.Have tried the steel wool thing(wrapped it around core then muffler packing over top but to be honest i wont bother with it again.

I was about to repack mine and have heard that with the modern 4 strokes the packing lasts a lot longer if you wrap the perforated center pipe in stainless steel wool then the normal packing over that. I have been told that there is what they call flame out happening in the muffler that burns up the normal packing pretty quick.

Anyone got any comment on this.

Anyone got any comment on this. Good quality packing lasts for ages,ive repacked my TL in the past and got 2-3 years out of it,as for the stainless steel as i said in my last post i wont be doing it again as it acheived nothing.

The stringy stuff from the bike shops is what your after for your fourstroke. Pack it in tight.

In some fourstroke dirtbikes, straight fibreglass packing can blow out the tailpipe pretty quickly, especially when they backfire a bit, like my 525 does on deceleration.

You can see this sometimes in the form of sparkly emissions from the tailpipe in certain lighting situations. It can help put you ahead in a race as the riders following you drop off one by one with asbestosis, pneumoconiosis, mesothelioma and other fatal lung maladies.

Therefore it does pay to use stainless steel wool or similar to wrap around the performated tube to "protect" the fibreglass from the sonic energy violence therein.

Being basically a tightarse by nature, I used goldilocks pads on the SX muffler on my 525, wrapped around the perforated tube using masking tape to hold it in place. I then packed the remainder of the capacity of the canister with the generic stringy curly fibreglass available at various outlets. It's holding together well so far and it's pretty quiet and my riding mates love me for it!

Thanks for that Humai

Thats what I had heard about the big four strokes. This will be the third time I have repacked my muffler. Makes a big diffferance to the torque at low rev,s
once you repack them.
Does anyone know where you can buy Stainless Steel wool? Might be off the the super market to buy Golilocks!!!

Cheers the advice. Going to go shopping tommorow and see what I can come up with.

I repacked my VTR with Silentsport packing, it's a fat, stringy fiberglass. A bit curly. I didn't use any other material, and I haven't blown any material after four years.

New World has budget stainless steel scourers for about a dollar (a pack of two).

I used 4 packs for my 2T muffler placed near the core (with fiberglass over the top), as it kept on burning just regular fiberglass packing within a few hours.

Seems to be holding up better than just the fibreglass.
