Yamaha put their hands up to that fault and have replaced free of charge the 9 mm nut with a 12 mm nut when bikes went in for a service or maintenance
Mine never got replaced at service or maintenance.
When I went to purchase the 12mm nut at the dealers they didn't seem to be aware of the issue at all.
They tried to sell me the old 9mm nut until I handed them the part number for the uprated one and asked them to just order that, rather than keep referencing back to parts list.
The independent garage I currently use knew all about the situation when I took the nut kit to them for fitting
Hi YamFazFan,
A request went out to all Official Yamaha dealerships telling them to replace the nut and washer as a matter of course whenever an FZS 600 came into their workshops to have work done to them, and the replacement was free, and the workshop was to put a centre punch mark after the info on the frame plate near the steering head. There was never an official call back as it was deemed to be a relatively small number of machines afflicted with this fault/problem and judging by the numbers of FZS 600 still about some 14 to 19 years later it sort of bears this out. And to be honest if this wasn't the case would we be the proud owners of our bikes or would we all be on Honda or Quackers.
Hi tommyyardin
I wonder if because my Fazer was one of the last in the production run it wasn't affected by this issue?.
The original 9mm nut never came adrift thankfully, but it's got to be a good idea to fit the uprated nut anyway isn't it.

Yes I think you are right --- fit the new nut when you replace the sprocket.
And I think as yours is one of the last by that time the fault with the thin shaft was noted and yours i s(maybe) ok--- read my post below

Mine actually did the opposite, and it took my mechanic supposedly 40mins to get my nut off!
That sounds so wrong....

Moot point, your bike craves a bit of rain.
More people are born because of alcohol than will ever die from it.
Fazersharp, as much as i totally get your point about '98's not having an issue, i would've loved to see your exact bike under the strain of all year round weather for the last 18 years.
Every bike is obviously different but yours has been a tad pampered.

:lol We all pamper those we love. My FZS 600 is pampered, (as is my MR2 Spider is pampered) the Fazer gets treated well, never ridden purposefully in the rain, has the best cleaning products on it (Oh no! Personal preferences again) oil changed on or before due, spark plugs every 6k or every other oil change, air filter every other year bearing in mind the bike probably only gets ridden two or three times between beginning of Nov and end of Feb. I purchased some carbatooter balancing gauges about a year ago so I am hoping to be able to get around to balancing them this week along the the new front sprocket

It's very weird that you should say that, i dunno if it's coincidence or a mistake, but when i put my bike number plate into the AJ Sutton website it always shows a a '98 bike, even though it's an 'X' reg and a 2000 SP model?

As I said its all history now as far as Yamaha is concerned, the FZS 600 has a reputation for being a reliable bike with a bomb proof engine as long as it is serviced regularly, OK it had a quirky issues with the front sprocket nut letting go but, only on some bikes. I wonder what the mileage was on the bikes with the problem sprockets, I wonder if the front sprockets had been changed on any of them? if that was the case had the nuts been done up properly.
Anyway YamFazFun, me, I'm just an old Joe Blow who rides and enjoys his FZS600, but it would seem to me to be a wise thing changing the Nut and washer when changing the front sprocket, Yamaha call it an upgrade kit so it's certainly an improvement even if some have found that the original was a bastard to get off as I did, as I said I nearly bust a blood vessel in my neck straining to undo the bugger, even with a 3 foot length of 1 1/2" inch galvanised steel pipe over the socket wrench handle and still managed to bend the pipe. The windy gun just shocked the shit out of it and it eventually let go.
I think a lot of that issue is caused by the 620 Locite, but its better to have that removal problem, which is manageable, than to have the sprocket come off messing up your output shaft or worse still causing you to come off when it all goes tits up.

EDIT
Sorry I didnt see your later reply about it being fused on,being the reason it took so long to get off -sounds like you have a thin shaft.
I wouldn't say my bike is pampered I just don't like getting wet, that's what the car is for. I doesn't get very dirty because of the dry riding and it is kept in a garage. I dont get to ride as often as I would like because of family and work commitments and so the mileage is also low its on 20k now 19 years old.

LOL! How long you been a mind reader Jules? I am just sorting out the stuff to remove the 12 mm nut if it proves to be a bugger like the 9 mm one was.
The mouth wash, tomato kethup and bananas play no part in the operation.

Removed the front cover, loads of crap around the front sprocket so the scoop out begins and suddenly once enough crud is removed to my horror the the sprocket wobbles.
The new wider nut has come off. I found the lock washer down below which had been bent round the nut as required
but some how flattened off.
I replaced the chain and sprocket in May, torqued correctly (imo) to the spec suggested for wider nut.
Hey Midden!
I bet when you started this post off you did not realise it would go on so long.

Agrees with you on that one Sharpie about the washer being pre-folded.
Looking directly down on the washer it is impossible to use both of the pre-folded areas as the folds are a quarter of the circumference away from each other, making four sided pattern and the sprocket nut like all others has six sides so no mater how you position the washer only one of the pre-folds will line up.
I think it was designed to have just one fold up and having the washer pre-folds this way gives you a very good chance that one of the folds will line up.
I just did an opposite one for good measure.
The Loctite 620 is quite expensive and as commented and only ever likely to use it on the 'Front Sprocket Nut'
So if anyone needs some for sprocket nut message me and i will post my bottle to you on the understanding you post it back when your done with it, that way a number of us can use it saving a purchase or two and all it will cost is perhaps 50 or 60p postage.

Good man.
I actually thought about the same thing, that I would buy one and pass it on to other members so long as they then pass it on to another member who needs it, starting a post and keeping it all there, sort of a community library.
I have a whole pot of red rubber grease that I will never use which I could break up and post out.
I don't do rain or threat there of. dry rider only with no shame.
Hey Sharpie! Same as that matey peeps, mahoosive great tin of Red Rubber grease 500gms/1.1lbs weight and £17 to buy, brilliant stuff for calipers and any place that is adjacent to rubber as it does not perish rubber like mineral grease does, plus its impervious to water.
I bought it for lubing the slider pins on the caliper brakes of my hairdressers car (MR2 Mk3), does not rot the gaiters. I used it lubing up the lower rear suspension linkages and needle roller bearings when i did my suspension upgrade a month or two back, as its not affected by water the ideal lube in this very wet and vulnerable environment.
I have often thought about things like carb balancing gauges, quite expensive to buy and its something you only use once in a while maybe once every year or two. That reminds me I still have not done mine bought the gauges 4 months ago and still in the box in my shed
A FOC-U Lending Library of stuff that everyone does not need to buy, but could be borrowed on the understanding its looked after and returned promptly when finished with. The cost to the borrower would be postage both ways, not sure how it could work or how one would set that up.
The problem I have found in the past with loaning stuff out is people either forget to return it or they lend it to someone else and it is now longer traceable.
But it is a thought. The only thing I would not lend is my torque wrench after seeing a YouTube clip a few years ago of a guy knocking a clevis pin in on car handbrake linkage with his torque wrench :eek :'(
Hi folks, Just took tommyardins advice and checked my front sprocket nut with my verniers and it's 9mm so I'm off to ebay to buy the 12mm version. Mine's the 2003 version and I expected that it would have had the thicker nut on from the factory. oh well, one lives and one learns. Thanks again for the heads up :thumbup
Still worth doing but from a certain age they sorted the issue with what I believe to be a thicker output shaft (or rather the correct size one ) which was the causes of the issue in the first place - some say
I don't do rain or threat there of. dry rider only with no shame.
Thanks Fazersharp, mines only done 9000 miles and the original sprocket still looks like new. I don't think the cover had even been off before. Do you think it would be ok to leave this nut on until I need to change the sprocket? All appears to be fine at the moment
