vibration

[sinto]

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

They're going to get foccin lazered if i find them

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

[sinto]

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

[HarryHornby]

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..... 


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 

[Jules-C]

Also check tyre pressures, wheel bearings, head bearings and swinging arm bearings

[unfazed]

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 )

[sinto]

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?
