Anyone used pink batts as exhaust packing on their 2 bangers with any degree of success? The reason I ask is, Kevin Rudd left a few at my place after he did my insulation and I was wondering if they would “stimulate” the packing in my kids pipes.

April 12, 2010 at 2:37 am #175758For the cost (not much ya tight arse :laugh: ) I would use the correct stuff as I am told the pink batts dont handle the heat as well and require packing more often. Pack it tight as well mate no matter whatever you use

April 12, 2010 at 2:48 am #175762Works brilliantly, and lasts at least a season,dont pack it to tight, just firmly, to tight will strangle the power
best idea is to try it and make your decission from there,
BTW works just as well in 4 strokes

April 12, 2010 at 2:50 am #175759Dunno about the bats but all you have to do is duck up into the ceiling and your in luck.
The last “tight” owner of my bike used some car carpet underlay in the front where it burns away cause he was to tight to rip the lot out.I use the DEP stuff $12 a re-pack, spose lot of re-packs for $40! Be hard to get it compressed as tight as original stuff though.

AnonymousWTF is Pink Batt?
April 12, 2010 at 2:55 am #175767hay mick when you try it give it a rev outside in the sun and tell me what you see ???
April 12, 2010 at 3:56 am #175768I’m going completely the other way to TB on this one.
Pink batts are fire rated to heaps of degrees, so that issue is a furphy perpeuated by motorcycle shops, who want your bucks, cause that’s their job, to stay in business.
I’ve been using bats for 40 years and i’ve also used the “proper” aligned, special woven & formulated ubeaut ridgy didge $25-50 a small pack bike stuff, Guess what?
Absol-bloody-lutely no difference in use, they both get the same lifespan, they both silence and deaden the note the same, and they both absorb the same, tell you what will make a bigger difference is your packing technique, like a Cone (so I’m lead to believe) you don’t have it too tight, nor too loose. The best way is to have it so it is a comfortable fit, this way it will deaden more noise and allow more spoogey crud to absorbed, too tight bounces the sound and doesn’t allow full absorption of both crud and note.
This I know, have done back to back trials looking for answers, and as TB will see in the next fortnight, my young blokes bike is quieter than a whipper snipper with a FMF silencer and my pink batt packing system.
Like the Ad says Mick… JUST DO IT,
(caveat if the bike catches alight you can always blame peter garrett, why not everyone else did, it’s not my fault I only installed it, it’s his……… )

AnonymousGood info there Bruce, based on your words of wisdom I’ll use some Pink batt when it’s time to repack the 300.
I packed Tyne’s 200 with the stuff from the bike shop, I thought it was a reasonable price at $15. I just used some electrical tape to hold it in position and voila!
April 12, 2010 at 4:03 am #175777On a safety note,should I wear a white suit and a breathing apperatus whist handling said batts and note the positioning of any down lights?

And i would do it directly under a downlight as us older fellas need all the help we can to see……
and Yet still it is Peter Garretts fault……….
April 12, 2010 at 4:12 am #175779I will take what you wrote on board Bruce as I always do coming from a man of your knowledge
. I did hear at Finke of two 2 smokers with flaming cans so to speak both packed with roofing batts :huh: I have noted when the two materials are side by side the batts are not as dense as the two stroke packing.
Other then that pack away with whatever Mick as I said before
TB
April 12, 2010 at 4:13 am #175780Mick with a head like yours you should wear that all day every day! :laugh:
Seriously though, you should be right for that level of exposure mate!

I’ve had a flaming can on a few occassions myself TB, once from a wicked curry, but i digress, as Menace will attest to (he saw a similar thing on mine when young Mick thrashed it senseless for 10 minutes), what you probably witnessed was the excess spooge alight in the silencer whence the pipe became hot enough to ignite it, quite common with flatout running on 2Ts. and yes you are right the “special woven” stuff is denser to begin with, but we can compensate by , unravelling the layers on the batts and rolling it like a cigarette until the desired density is reached.
I pull your leg not sir not on a subject as serious as sound and savings.
