Zorst repacking

[Falcopops]

So now the bike has passed all the inspections it needs and is officially a resident of Australia (more than I am by the way) the time has come to take off all the standard bits and bow to the bling.

I only get a chance to get into the garage once the kids are in bed and a few house hold chores are out of the way, so it’s normally 9 to 10 at night before I start and don't usually pack up 'till 1am and this is the third day so I’m knackered.

In first couple of nights I pulled the bodywork off first to give me some working room, removed all the anti-bling parts and sorted out a couple of little problems. When I was fitting the exhausts I noticed a little bit of discolouration of the CF, so I gave a few taps and found a hollow point, bugger.

So last night I took them off again, drilled out the rivets and pulled them apart. How I wish it was as easy to do as to type! There’s no mention of the swearing, burnt fingers, swarf cuts, minor Stanley knife lacerations or fag smoke in the eyes whilst wielding an electric drill. The packing was burnt away in one can in a localised area (didn’t take a photo) so I’m glad I did it now.

Here’s a pic of the internals.


What do you reckon to this gauze that was wrapped round the perforated pipe?

I was going to wrap a layer of SS wool instead of reusing this. The gauze is very fine and my thoughts are that it may be too fine and being so thin doesn’t protect the packing. Any thoughts?

There isn’t any lining in the CF tubes. See


So I used this heating duct tape (thickish ally foil I liberated from a previous employer a while back thinking that it would come in handy one day).


To line the sleeve.


Like the new number plate?

My thinking is that it might provide some protection to the CF by means of heat reflection and localised dissipation and even if it the stick packs up it’s not going anywhere.

So my questions.

Gauze, SS wool or both?

Tape – a good idea or do you envisage a problem?

How the hell do you get the ends back into the tube (bloody tight fit)?

Go with both the gauze and the SS wool. You know you want to.

or fag smoke in the eyes whilst wielding an electric drill.

LOL....I have so been there. I can picture it in my mind, the squinting eyes, the pulled face, did you get any smoke up your nose, that's the final straw, time to step back, 'chill out' and finish the fag.

Good work on the cans

How the hell did I manage to double-post like that?

Right, I'm off to the pub. See you all tomorrow.

I recently repacked my cans with some material I bought from a exhaust manufacturer.

First step was to wind SS wool around the core pipe.
Second step was tightly rolling the packing material around the core.
The packing material was some sort of 1cm thick kevlar like cloth.
As an extra I used some copper wire (from electrical wiring) to secure this all and make is easier to showe the entire package in the outer shell.

The difference after repacking them..... none.

Yeah - looks like a new take on those "Darren & Tracy" window strips.

How long have you and Vic been an item?

[Falcopops]

Nice Andy.

I've no idea what this thread is about but I enjoyed voting anyhow

Good idea with the tape. CF dies a death when people dont pack the can properly or dont repack when the noise increases (as the packing is shot)
That should provide a decent enough liner between those nasty gasses and the CF..

I'd wrap with wool as well as the gauze..

Plate looks Ace! Who the fek is Dale though.. I thought your name was Vic...

No idea what the gauze would be for - my thoughts were exactly the same as yours, put there to protect the packing but too thin to really make much difference.

I would definately go with the stainless wirewool, but not so sure about the gauze - if it's that fine then you may not get the deadening effect of the damping because you have covered all of the perforations in the core.

As for the tape, can't do any harm but I was always under the impression that it was the vibration/pulsing from the engine that caused carbon sleeves to disintegrate, not the temperature, but I could be misinformed. I have noticed that most high end carbon cans (especially those for twins) these days have an inner Titanium sleeve under the CF to protect it.

[Kwackerz]

Yup, the pulses are what cause the problem in the first instance, then when the fekked / missing packing isnt noticed (sound increases, often hard to notice if you ride the bike a lot) the heat gets to the inner side of the CF directly, brittles it up and whumph... a short period of time later, CF shot to fek.

It doesnt help when the can is repacked by the owner incorrectly, it's easy to have a gap in the packing wool, which is then exploited straight away by the exhaust gasses..
