Just took the sprocket cover off for a bit of cleaning/inspection. Found that the sprocket is only being held on by the tab washer. I was a little surprised as although I knew of others having the problem it never happened on my previous Fazer.
Within 5 minutes I'd phoned the local stealer, they'd taken my details and submitted something to Yamaha. Waiting to hear back to get it booked in and fixed.
Hello, How did you get on with Yamaha? I've noticed that my sprocket nut is the old 9mm size and I'm not sure if I should just buy a new one or ask Yamaha to change it. As the bike is 03 with 37k miles I'm not sure how interested they will be.

They haven't got back to me yet, I'll chase them in a day or so.
From the article (see link in first post) it shouldn't matter how old the bike is or if it's been serviced outside the dealer network. I guess the dealers get paid by Yamaha so probably don't give a toss how old it is.
For the sake of less than a tenner buy one and save an expensive gearbox rebuild, if you already know theres a problem and a cheap fix you will only have yourself to blame.
I have a shiny new nut and tab washer, it has been sitting by the bike for months now, maybe I should fit it... :rolleyes
Fitting the correct nut myself seemed the easiest choice, faffing around and getting it booked in to suit some dealer's timetable would have been far less convenient.
What still amazes me is that when parts suppliers look up the part number on their microfiche and ask for the old nut, Yamaha still provide it instead of automatically sending the upgraded version. Now maybe the part is common to some other bikes that don't require the newer nut, but knowing that if it is for an FZS600 they could end up footing the bill for a final drive shaft replacement they ought at least to query it.

But there is a known fault with some output shafts being too small. They will replace the shaft if need be. With a crap shaft the nuts will come undone whatever.
The shaft is only too small if the nut has come loose and buggered it up, if the nut is still tight and always has been the shaft should be fine, I don't think there were any bad shafts made, I stand to be corrected...

That would make sense, especially as the mod is a wider nut.
Contacted main dealer regarding the dreaded nut and their reply was"Unfortuately the Yamaha FOC campaign has long finished" Locknut £4,20 washer £4,10 inc vat. So hopefully the shaft is ok and it's going to cost £10 for piece of mind.
Andy FZS. When I bought one the nut and lockwasher came together in a sealed plastic bag and described as a "nut and lockwasher kit" Part No. 90891-10124, for about £4.50. That was a good while ago so I suppose it may have changed now. Just make sure they give you the 12mm wide nut before you hand over the dosh.
Yamaha will honour this.I contacted them a couple of months ago (Yamaha uk head office)and spoke to them.They wanted the bikes frame number and mileage.If it fell within the affected batch I could take it to my nearest main dealer and have it checked and rectified if neccessary.As it was I ended up doing it myself,less hassle.My bike is 11 years old with some service history but this made no difference.
Checked my front sprocket last year and found nut and shaft completely knackered. Contacted local dealer (Skellerns) they checked with Yamaha and, after taking a few measurements, agreed to fix the whole lot FOC! And this on a 12 year old 28k bike. The repair took longer than ideally i would have liked (about 3 weeks) but i was just amazed they agreed to do it. You also get a free oil and filter change out of it .
If it ain't broke.......just tinker with it a little anyway!

Just chased CMC Clay Cross, they are waiting for a modification number from Yamaha and will then get it booked in.
I want them to do it as the nut is loose (although held by the lock washer so only about 5 degrees free movement) so there is possible shaft damage.
Hi all,
I checked mine out a few months back (in the snow...) and my nut was indeed the wrong one.
Replaced it with the correct nut after checking the shaft thread was OK.
If it helps, I've added some pics.
Why Yamaha didn't notice this in production is beyond me...

Thanks for those pics, checked mine and it has the old nut, no signs of any wear yet though. printed off all this info and will be taking along to my dealer to make sure they order the correct nut.
Is it absolute necessary getting this sorted? I'm pretty sure mines the smaller nut :\ however i was told it never effected the 2003 foxeye models? :rolleyes
well mine is the 2003 foxeye and for the sake of £4 id rather have the piece of mind that its done, rather than being paranoid and checking every weekend.
