hi!

Well a friend of mine is selling me the whole high mount system for my 620ie 2002, Akra, BUT one of them has a wear hole, inside part, just about in the middle of the can, inside face... guess the tire did it some-how, my question is: is there a way to repair it? the hole is about 1.5 inch wide, you can see that is not that bad and I was wondering, since is the inner face of the exhaust if I could just put some CF little plate on top, rivet it and that's it.. ideas?¿  [popcorn]

if you were to repair it then i would do it from the inside

but the integrity of the CF is going to be in doubt anyway

I wouldnt be surprised if you couldnt get a new CF sleeve , the Q is how much ?
i dont care if you have been a mechanic for 10 years doing something for a long time does not make you good at it, take my gf for an example shes been walking for 28 years and still manages to fall over all the time.

Looks like a burn hole due to the cans not being repacked to me.

Get it very clean and epoxy woven cf over it.
Make sure the 2 part epoxy soaks the cloth but brush off as much excess as possible. Would be less noticeable if you could do it from inside.

Its not a structural item so you don't need to get too fancy with ovens and vacuums and so on.

Edit

Something like this, if 6"is good enough.

1) Go to your local marine or aviation supply shop, or online these are the ones I go to:
- West Marine
- Wick Aircraft and Organ Supply
- Aircraft Spruce
- McMaster Carr
and get some CF cloth and high Tg 2-part epoxy.

2) sand down the rash area, and surrounding areas you want to blend (perhaps the whole can, the weave is going to be terribly difficult to get lined up, if you don't care cool, if you do just plan to wrap the whole can and leave a seam on the inside, towards where the tire is).

3) paint a coat of properly mixed epoxy on the repair area. 

4) put a piece of CF cloth, cut to size, on the repair area.

5) paint epoxy on the the cloth, check it soaks in real good.

6) squeegee the excess epoxy off and all air bubbles out (note, this is the point where if it was structural, you'd want to vacuum bag it..., but it's not, so don't worry).

7) if you happened to chose a sun/UV-cure epoxy, hope it's not too cloudy, stick it out in the sun for a minute...  Otherwise stick it out in the clouds for three...

8) sand, and repeat (3)-(7) until you're happy with the blending and the thickness of the CF layers you have

9) sand and polish to desired sheen.

OR... stick'em on the bike, as is, hole and everything, and when people comment say "Yeah... You wanna see the scars?  ;D"
