Don't know how I haven't noticed before but only seen this a few days ago ..
Is it normal?
Thanks for any replies ..
-
Yep I have that - only on my 98 its 1 hole on mine and it is to let out water condensation from what I understand, and unless you have just washed it those water "strips" are where you have just been out on it and the condensation has come out of the holes and been wind blasted up the side
-
Ahh yes that makes sense actually. Thank you for quick reply too..
Yeah just mid way cleaning it after 1st proper blast this year :)
-
I said that because I see those water strips on my bike that have come out and then dried. Its starting from cold - then hot creates the condensation but after a proper ride up to temp it evaporates and no longer comes out the hole or in your case holes (im sure my 98 only has 1 hole ) I wonder why that is. Did they change it or has your past owner drilled another one
-
I thought myself was possibly holes for water condensation or possibly something like that .. an uneducated guess from my part mainly tho ? Lol .
But as you have said about it having 2 holes as oppose to 1 ..
The last owner hardly touched the bike, said the only thing he did was add a scottoiler. . Never said anything about the end can.
The one before that, the 1st owner bought the bike instead of taking up golf, but decided after few 1000 miles he was less a biker and more a golfer .. lol
Il have a little look online, unless anyone with 03 can comment otherwise? ? :/

Hi, just a quick questions while were discussing the end can :-)
I seem to have a problem with mine, mine seems to blow where the black pipe goes into the steel end can. obviously there is no way of taking it apart and now parts that can be replaced, so just wondering whether my exhaust has come to the end of its life... or whether this is just the way its supposed to be?
When i start the bike and put my hand around where the gap is i can feel it blowing and when i clamp it shut i can feel slight pressure against my hand.
Hopefully someone can check this, even if its just from starting your own bike up and checking as I want to fix all the niggly little things wrong with mine.
thanks
-
For me at least - the slight blowing is normal, I would call it more of a leak than a blow with no noticeable noise. No rattle though
-
no rattle on mine either, when i give it a bit of throttle the blow/leak increases as you can imagine.
It might very well be normal and just me trying to find faults to fix, I did buy another exhaust off ebay but it was exactly the same, but the one i bought off ebay was in worse shape than mine.
Some people said it can be fixed with sealant of some sort, but if its just the way its meant to be then i might not bother.
Although as my engine vibrates a bit i wasnt sure if this would have relevance?
-
Ive had a couple of end cans go like this, first one I replaced, when that one went the same way I filled the gap with gumgum smoothed it round with my finger and when set rock hard I painted it, looks good and you would never know its been repaired....could be a MOT fail if its blowing...
-
Is that the same as fire gum?
I looked on halfords and it's made by the same company "holts"
-
Yeh, thats the stuff...its a bit messy but easy to wipe off before it sets, bit of masking tape around the pipe and can would help but
Remove it as soon as you have finished applying the gum, if you leave it untill it sets you'll never get it off.goes rock hard when set...

HEY - you got 3 !!
-
Yep & the 3rd hole is visible in odbguys pic also.Sure it's Yamaha engineered :).
-
oh yeh it has im sure that my 98 only has 1 hole - OEM can
-

Ahhh haha as if I didn't spot that 3rd hole ..
Well at least we have solved that mystery a ;)
-
Ok just looked and I have TWO holes. The one on the funnel shape part and the one on the tube part furthest away from the seam
-
@ Silverlegacy. Yes, your can is on the way out.
The only good news is that if money's tight you can bodge it for a fair time. I used high temp silicone sealant to bung up the gap between the inner and outer bits where the pipe enters the can. It did get through a couple of MOTs that way, but the rattle got too irritating in the end.
The problem is the inner mild steel rusts through down at the bottom (despite the drain holes).
I dismantled mine:
(https://s19.postimg.cc/oz8snurc3/exhaust.jpg)
You can see the two inner flanges have rotted through (ignore the slot in the stainless to the left, that's just my clumsy hacksawing). Not shown is the mesh sleeve that the internals are spot-welded to, that's surrounded with mineral wool before being slid into the stainless outer. The mesh gets rusted away at the lower end too so quite a bit of the wool had blown out.
-
Thats an interesting photo of whats inside, did you take to bits to repair it.
Also I thought that the end can was a "slip on" and so you would expect some leakage of gas around the pipe
-
I just took it apart for curiosity's sake, I can't weld stainless steel so repair wasn't an option.
The left-most mild steel cap is welded to the stainless input pipe though the rest is a press fit to the stainless outer so would not have been perfectly gas-tight.
-
+1 ... interesting
Good photo, thanks for putting that up.
I have wondered what the internal structure is like
That answers it nicely :thumbup
And supports the idea of silicone sealant on the outside for older ones when that mild steel cap starts to go.
Good to see the insides
-
Your connector pipe on the left seems to be stainless steel, as far as I knew it was mild steel
-
Thanks Fazerrider :)
Always wondered what the inside looked like, but was too scared to hack mine up. hopefully if i get some firegum it will sort the job.
Do you think this would have any bearing on my mild vibration problem? at around 5k+ RPM.
-
@ Fazersharp. The inlet pipe seems to be a different kind of steel, almost no rust spots and a similar shiny appearance (where the black paint has fallen off) to the stainless of the can, but it's magnetic whereas the can isn't.
Silverlegacy: the slight vibration from the engine at 5-6k is just a feature. Best solution is to keep the engine speed up above it. :lol

Ah i see, i think i might of been using feature of the bike a bit too much then, time to twist the throttle a little more.
Although i only really commute to work on it and not much road to open it up and mainly through town.
Thanks anyway, might find another way home tonight, after stopping off at halfords for Firegum
-
Some cheaper lower grade stainless is still magnetic, try it on your sink and you may find the bowl is not magnetic and yet the drainer is.
-
just curious fazer rider, does the left hand cone line up with the outlet hole at the end of the exhaust?
reason: sharp spike hammered straight down the length of the exhaust.

Well, sort of. That is, the cone is central and so is the outlet, but the outlet pipe is at an angle so your "tuning" mod (if that's what you're hoping for) will have to go through the side of that pipe in order to stay central. Chances are that the force needed to drive a spike down there would end up ripping the welds apart, particularly the spot welds to the mesh. So you'd end up with a can full of mangled metal that sounds bad and performs worse. :lol
-
hmm, i suppose itd be worth a punt as standard exhausts are easy to come by, i knocked the hell out of the outlet and its made it louder but still not loud enough without changing it.
it did make it pull a little better but barely noticeable.
also what mesh? haha
-
on the outlet youve got the smaller tube in the middle all the gasses come out from, i cut out the outer ring around it, its welded to the next part down obviously but makes it sound a heck of a lot better and improves acceleration a little (barely noticeable)
-
2 holes on my 02 Fazer, they are for water to drain out but I never put water down the end of my exhaust :b Mine does blow a little between the can and the pipe, more noticable in the winter due to the exhaust being visible but it is slight.
