vibration

[unfazed]

Put a large diameter washer on the bolt on the exhaust mount on the right foot rest.

i fitted 03 hangers to  my 98 didnt give me any vibrations or problems, maybe youve lost a wheel weight

Nope, checked, all good there and I've lost a weight before and think I know the 'feel' you get with that, but I'll take another look to make sure, better check twice :-)

Hi Sinto, I'm far from a mechanic but I managed to balance my carbs using the guide from here.  It's not too bad to do, one tip, when you head is in the engine trying turning the adjusting nuts try not to shit yourself when the fan kicks in.....  :lol

I've done a fair bit of pulling engines apart and rebuilding them, I'm not worried at all of doing it, just like to research and cross the T's etc

And as for a missing wheel weight, good call for my bike, I've had a vibration on the bars that's not the usual 6k buzz (I get that too) it's more like the bars are moving left and right very quickly I wonder if it's a wheel weight 

See above my thoughts
My bars aren't moving at all unnecessary, that's why I don't reckon it's a list weight as that's the sensation I got before on another bike I had

I'll give that a try, I've got a spacer washer somewhere and it's easy enough to put it on a try it )

[sinto607276]

I'm just trying to eliminate the small stuff before I get a carb balance, which I'll get done anyway as it's good for the bike anyhow.

A mate suggested it's maybe because I have a hole in my exhaust, where the pipe goes into the silencer, see pics, so I was wondering what your thoughts on it being that?

[mickvp]

If you shoogle that bit does it rattle or move very much. I doubt it is that but I would want to sort that anyway just to be sure

No mickvp, doesn't rattle at all but it is leaking, was just curious if that was anything to do with it.
I'll pm you in a couple of weeks and we can sort something out re the carb balance?

[Paulfzs]

all fzs 600 exhausts are like that.

[sinto607276]

all fzs 600 exhausts are like that.

Surely they shouldn't have a leak before the silencer?? In fact, I don't think exhausts should have a leak anywhere.

[anutz]

so mine is similar but i don't use it - have a different can...



And

[sinto607276]

Yeah, they're all like that to look at as far as i know, but mine's blown within that gap
So I'll get it welded / braised round the whole lot and that should improve the exhaust even if it doesn't resolve the vibration.

Sure thing Colin, just fire me a PM when you want it and we will arrange a time and place to meet up/do it/whatever

Yeah, I'll work on getting the wee things sorted first, don't know if it'll affect the carb balance if the exhaust is blown? But I have contacts who can weld it

From this thread about the condensate drain holes, rusting inner plates etc....., there is a a good picture showing the structure of the silencer

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:





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.

Yeah I read that thread with interest but no way am I cutting my pipe down like that lol but been asking my welder who's able to do something, so just need to get it to him now, should do me for now and stop the onslot of it getting worse quicker, but as i say, don't think this is causing the vibration feeling I'm getting but it won't hurt to fix it and see first before getting the carbs done which I really will be getting done anyhow as don't know when they were last done

[mickvp]

Aye, definitely won't do you any harm doing the carbs as you say Colin. It smoothed things out a good bit on my 600, ran a lot better after that.

True Mick, I know for a fact it's been at least 4years as i know the 2 previous owners and they didn't do them, just need to organise a time that suits us and we'll get it done.

Hi Guys

Sorry for the delay in replying.

Rear pegs made no vibration.

Standard exhaust fitted, no difference.

you will have to let me know how the welding goes, as I had my bike serviced the other day and carbs stripped and cleaned and sync'd and mine still has a vibration patch between 5-7k.
The garage said again the bikes running fine but my exhaust blows in the same place as yours, tried using some gun gum to fill the hole as read about on it here earlier in the year, but its not working too well as its just a pain to get it in the gap and make a good seal.
I did get another pipe off ebay but it had the same problem, so maybe its just one of those things with the original exhaust?

[Davew]

Silverlegacy-my bike has the same annoying vibes you describe and I've been through absolutely everything to get rid of them with no luck, so if you manage to fix it please let me know!  I can confirm that (in my bike at least)  its not the exhaust, downpipes, fuel tank, fuel tank mounts, pegs as I've ive replaced all of them with no change!  also done several carb balances.


hope you figure out what it is, but it seems like some fazers are made a little better/smoother than others!
