Ok, I will have to just change the chain and front guide then. Hope that will quiet it down. At this point I have no more clicks in the chain tensioner.

Could someone tell me the complete procedure to change the chain. From removing the tank to putting it back on. Do I need to remove the engine from the frame. What about the tensioners - can I change these as well, without taking out the engine and without removing the head.


My engine ratles like a box of nails. I would like to change both chain and tensioner but preferably without removing the engine.


Enlighten me!!!

What you are saying is, if the needle jet is worn, change the needle as well and if the needle is worn, change the needle jet? Basicly if ANY needle or needle jet is worn - change the lot?

Ok, so I did a bit of googling and found this: http://www.factorypro.com/tech/needle_jet_wear.html
 
That explains what to look for concerning wear in the needle jets pretty well. All the explanations of the symptoms match what I am seeing on my bike. So now I can't wait to tear into it again.
 
Do you know what I am looking at concerning the price of the needle jets? Should I also change the needles? Maybe it's worth considering a kit containing these parts - if that exists. Does it?
Any other parts I should consider changing when I'm in there? (besides the needle jet o-rings)

I guess I will try  to adjust the mixture screws back and syncronize the carbs once more. The first time was before I cleaned them.

If this doesn't help I think I will change the camchain, adjust the valves and go through the carbs once more and check for wear. But this will have to wait till the snow comes.

Thanks for all your input.

I got this ´98 model fzs600 that I bought a couple of months ago. It has been crashed and is not very pretty but basically runs fine. The idle is i bit rough though. It surges maybe 2-300 rpm up and down. Also when riding in slow traffic in 1st and 2nd gear the bike "jumps" a bit. It's really annoying as my daily commute is in heavy traffic.
 
I have done a bit of work to solve the problem, but no luck. I have tried the following:
 
Changed plugs to NGK iridium
Changed the plug caps to NGK
Changed the air filter element
Cleaned the carbs
Synced the carbs
Adjusted the throttle sensor
After changing the exhaust to a set of Motad downpipes and Viper end can I also tried to richen the idle mixture by turning the mixture screws out a few turns.
 
All of this has had no effect on the problem. Also the problem have been the same with original and aftermarket exhaust.
 
Whats the next move???
 
 
When cleaning the carbs I also checked the camchain adjuster. It's on its final notch and I have a rattling sound especially when the engine is cold, so I need a new camchain. Can I exchange it without taking of the top. And what about the camchain guides?
 
Thanks,
Mads
