Getting vibration through handlebars that I've not had before :(
Only thing I've done recently, or when I've noticed the vibration, is changing the rear footpegs from a 2000 model onto my 1998. Admittedly it moves the exhaust back a wee bit but don't think that's the problem but I could be wrong, so any of you guys got any ideas as to what's happened?
98 bike, original exhaust, standard air filter, 24000 miles.
Do feel it coming on even after a short run, 10 miles, to work and I do like to use the rev range and done so before changing pegs.
Cheers.

When was the last time you balanced the carbs? Worthwhile doing that to see if it smooths things out. I can loan you my carbtune if you don't have one as I know your local to me :)
Is it more vibey over the whole rev range or just at a spot/spots?

I've never balanced the carbs mick, and tbh I really would need to read up on it to see how to do it.
I'm just wondering why it would start doing this all of a sudden or is it just coincidence it happened after I replaced the rear pegs?
I would say it's more noticable about the 5k and upwards

I can give you a hand with it mate. It's a piece of piss, I did my old fazer 600 a couple of times (I think there is a guide on here for it somewhere actually, maybe in the Hanes manual in the downloads section)
Changing the pegs may have highlighted it, but it only takes for them to be out a bit to cause some vibration on the 600s, especially in the 5-6k rpm range.

it was the first job i did .....

Here's the guide http://foc-u.co.uk/index.php?topic=91

looking at mine in my first post i need to balance the 2 sides now!
Another job to do!

Cheers Mick and anutz, I know what I'll be reading on my lunch break tomorrow then ;)

Just give me a shout if you want a loan of my gauges/a hand mate. No point spending £50 on one when I've got one here

Yep Mick, taken a note of your offer and will prob take you up on it (beer tokens at the ready) once I've read the details of what's involved to get my head round it first, it's not at the point of I can't ride the bike, but I want to nip it in the bud before it gets worse.
The other point to take note of is...I've only had the bike a couple of months, not sure if carbs were balanced before, but I know the two previous owners, so will ask them.

Saw this in anutz thread....

"Compared to the SV650 the Fazer 600 would generally not have enough torque to trundle around at idle without slipping the clutch.
As said in previous post carb balance and TPS setting will help and set the idle speed to 1200rpm"
My idle is just above 1000, could adjusting this make the difference?

You definitely want around the 1200rpm mark, the bike engine will hunt around otherwise, and be a bit of a pain warming up, especially in cold weather if it's lower than that.
Make sure the bike is at operating temperature before balancing, take it for a 10 minute spin up the road.
If the carbs haven't been balanced recently then you will notice a nice improvement, especially when slow riding in traffic for instance.
It will also very slightly alter the tone of the engine as well, as in a little bit quieter, just because the fuel distribution is functioning in a more organised manner.

Cheers darrsi,
I didn't use it for work today but tonight I went out and started it up, let it warm up and let it idle, noting it wasn't at 1200 revs, think it was more like 900, so I duly changed it and now it's running at near enough the 1200, so my question really is, do you think that alone would sort out the vibration or will I, or should I still, do a carb balance?
-
Hi
Just done the same mod today, will let you know over the weekend if I experience the same issue.
Cheers
Doggy
-
easy change wasn't it? Yes please, let me know how it affects yours, if any. Original exhaust etc?
Personally I don't think it will but would be curious to know, cheers Doggy.

i fitted 03 hangers to my 98 didnt give me any vibrations or problems, maybe youve lost a wheel weight
-
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
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 :)
-
Also check tyre pressures, wheel bearings, head bearings and swinging arm bearings
-
Put a large diameter washer on the bolt on the exhaust mount on the right foot rest.

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 :-)

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

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

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:
([url]http://s19.postimg.org/oz8snurc3/exhaust.jpg[/url])
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 :(
-
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.
Doggy
-
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?
-
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!

My bikes going back to the garage Friday for another carb strip and clean as i had it done two weeks ago and wasnt entirely happy with how he did them so he said he will do them again for free (guilty conscience)
I am going to him to go over all the internals and check needs and jets and everything this time, worst case if anything needs changing then this may resolve the problem.
Hard to tell how things have worn since 1998 when the bike was new, but its only done 36k so hopefully theres still loads of life left in it.
-
This is all just my opinion but they all seem to vibrate to some extent at around 5k so I don't think that vibration alone is an indication of there being a problem with the bike. If you've got a drop in performance as well then yeah you've got a separate problem but I think that vibration is just a trait of that model Fazer and that it's due to something in the design of the bike rather than an indication of there being a specific problem with the bike. Cleaning carbs isn't going to get rid of that vibration. I'd say if you put a brand new set of carbs straight from the factory into your bike it'd still vibrate at around 5,000RPM so you'll probably have to live with it (or get a different bike). It doesn't bother me at all I just stay above or below 5k and that's it really problem solved :lol
-
I really wish i could find another fazer close to me so they could either ride mine or i could ride theres to compare them.
I have heard alot about them being a bit vibey but i thinkmy patch between 5-7k just seems be a bit to much, i am pretty sure the fazer i had about 10 years ago wasnt anything like this and I used to love pushing the engine, where as this one i have now i feel like I have to hold off or try and stay below 5k.
Maybe its more to do with worn parts than clean carbs.
Hopefully will have more info come weekend/early next week.
