This is only way I can describe this. Any gear when applying throttle, all I can hear and slightly feel is CLUNK :rolleyes , CLUNK :rolleyes ,CLUNK !! :rolleyes :eek :rolleyes :rolleyes !. Clutch in and free wheel - no clunk. The clunk is getting slowly louder, don't know how long it would last before Clunk goes to Crunch !!. When just sitting ticking over all is ok, just when you are moving creates the Clunk.
Any ideas on where to start looking welcome and will be big help. My problem too, is time, if this is strip engine, could be long fix.
Oh, if just sitting and first gear, front brake on, slowly let clutch out , will pull no problems with no Clunk, only when moving does the clunk start.
Peeved as it great day for run. :'( :'( .
Oh, 2001 FZS 600 with just over 64 thousand on clock.
That'd be the front sprocket wear. The teeth have hooked and the chain clunks as it drops into the teeth. Would always recommend replacing both sprockets and the chain at the same time.
You can alleviate the problem by careful adjustment of the chain but replacement is the right way to go.
Fwiw I recommend and use myself, DID HD gold X-ring chain and renthal sprockets. Keep away from those kits with JT sprockets in, they wear too quickly and take the chain with them. I get around 40k-45k from my chain and sprockets.

Thanks for replies. Had been thinking of new chain and sprockets. I changed the front sprocket last year and took it down to 15th and also changed the sprocket nut too. Ive no idea what age chain is , as I never got told that when I bought it. I do keep it well lubed as bike is use the bike weekly. Will have a look tomorrow and see how chain is running over front sprocket. Hope that's the solution. Thanks again.

Put the bike on the centre stand and try and pull the chain off the rear sprocket, anymore than 5mm and your chain is heading for replacement. See file attached
I had a chain which broke one of its link plates on the inside of the run. That gave a regular clunk and it took me ages to find the cause because it was so hard to see the crack. Must have done a thousand more miles before I spotted it… amazed the thing didn’t let go.
Opps :rolleyes something went wrong again. Ive heard about pulling chain at the rear sprocket but never tried it. Will give that a try tomorrow and see what happens. Ive put old sprocket on again and the chain seemed to run over it a bit smoother. Again see how that goes tomorrow.
And yep you can feel it through the foot rest. The louder the clunk the more you can feel it. It starts from 1st and through to 6th. Most noticeable at low speeds in higher gear.
Ive also had a wee look and ive had bike about 2 years and done around 10000 miles in that time. So maybe time for new chain and sprockets, as I have no idea when they were last changed.
Will give it a wee test run tomorrow to see what the difference is in the sprockets.
Thanks again for replies and I hope this one posts. Will let you know what happens tomorrow.
If you're feeling it through the footpeg it's most likely a sticky chain link.
Sprocket is a bit worn, but not that bad.
Look at the lower level of the chain, a sticky link will be at an angle, rather than horizontal.

Well as I said I put old sprocket on last night and,,,,, no Clunk today . But the old sprocket has signs of hooking on it too.
Was a bit worried as it started to clunk quickly. But as I said was thinking of changing chain and sprockets. Going to be costly month as need new rear tyre, front brake is close to edge, and now chain and sprockets. Wee bit of overtime needed.
Thanks for pointing straight to sprocket. . Help well appreciated.
Oh, and tried pulling chain at rear sprocket. And it does pull out :o , probably about 3mm without much effort.
Well time for coffee and thanks again.
I had the same symptoms and the sprockets were not in bad shape but it was the chain that had a tight spot. I changed both sprockets anyway along with the chain,its its great not having the clunk after putting up with it for too long.
I don't do rain or threat there of. dry rider only with no shame.

It is best to set the chain to the tightest position half way along the swinging arm, this way you are pulling the most worn section of the chain from the sprocket.
In any case a new set of sprockets and chain are needed.
Yep , new chain and sprockets on shopping list. Had a look today for old riveting tool I once had, cant find it :\ :\ , so that could be on list too. Was nice not hearing and feeling that noise today. Finished work at 5am on Sat morning and was wondering if I was going to make it home. And yep that's the way I adjust the chain, trying to find tightest spot first. And on paddock stand. Tried it once as it say somewhere in manual to have the bike on side stand,,,, no way could I figure out how you could set the chain this way. :rolleyes :rolleyes .
Easiest way to adjust the chain on the Fzs600 is to find the tight spot and at a point under the end of the rubber swinging arm protector, push the chain up and it should just touch the rubber, if it doesn't it's to tight.
