Can you explain as to how it wasn't torqued properly??

Re: sprocket nut - fazersharp - 13-07-15

Im still saying that I have not seen a single 98 owner who has had this issue with an untouched factory fitted nut.
My personal theory is that the 1st bikes came out of one factory and then when the sales took off more outsourced factory's were needed and that is why later models suffer from the wrong spec size shaft being milled from the other factory's.
My 98 17k miles no problems yet although I do have the new nut and monitor the oem one and will change when i do the sprocket and chain

The old fear of 90Nm recommended and 80Nm used.

Mine failed originally at 15682miles, a friends failed at 17100miles, but I have come across one on a Thundercat which failed at 12750miles.

I have tighten all I have worked on to 90Nm withou issue

The Fzs1000 is 85 on a 9mm nut, granted the threads are coarser.

Re: sprocket nut - fazersharp - 14-07-15

It all started a couple of years ago, after reading about it here I rang local dealer who rang yam with my reg and engine number and they came back to me to say the note does not cover my bike.
Then on looking on here I started to see a pattern in that I could not find a 98 owner who had the issue, that was before sinto and snakeyprince joined so now there are another 2 98s to add to the list of (as yet ) unaffected.

If the issue is an undersized output shaft then I would deduct that those shafts were not made in the same factory as the correct ones, I propose that 98 shafts were all made in one factory and later bikes all over the place leading to a hit and miss on the shaft size / nut problem

Have younger FZS600s suffered a nut-shedding incident with an untouched nut?

Re: sprocket nut - Dead Eye - 14-07-15

Since the first ones were made in 98 I doubt it Wink

Re: sprocket nut - fazersharp - 14-07-15

98 is the youngest and as far as evidence (here at least ) has shown the issue has not affected them

Here is my post about this in 2013 http://foc-u.co.uk/index.php/topic,9920.msg101931.html#msg101931

Re: sprocket nut - Panthor - 14-07-15

Wouldn't the 98 be the oldest fazer.
My 2003 is younger and the nut was untouched and I discovered the free play on it so changed it

Re: sprocket nut - Dead Eye - 14-07-15

My bad, definitely some confusion with younger vs older haha

Re: sprocket nut - fazersharp - 14-07-15

I think what fazer rider meant was younger being - older, as in made before 98

So the 1st fazer fzs 600s made in 98 are ok and its the later (younger ) models 99/2000/2001 etc that have the issue

The answer is YES and its only the younger (99 onwards) that are affected

Re: sprocket nut - darrsi - 14-07-15

fazersharp, I wonder if the small fact your bike has never seen rain before has anything to do with all your nuts and bolts remaining firmly in place? :lol

My nuts have seen plenty of rain and they're firmly in place I think :rolleyes

Oops, just realised your talking of nuts on the bike :lol

Re: sprocket nut - fazersharp - 14-07-15

Well that could explain mine but what about the other 98s

And you are wrong -- my bike has seen rain because I have showed it some pictures,

You could at least drive through the odd car wash every now and then as a treat. :lol

Re: sprocket nut - fazersharp - 14-07-15

I sometimes ride through damp patches where the sun is shaded from the road
