I'm sure you folk are well aware about the well known sprocket nut  issue?
Well after buying the bike last year I was delighted with it even if I had only done 10-20 miles before tucking it away for the winter! As with everything I've owned/bought I always like to strip it down and check all the wear and tear items e.g., pads, calipers, seals, bearings, bushes and well everything really. So I'm a bit pernickity so had a list as long as my arm with things needing done which probably didn't but anyway this bloody did!!!

Yep good to get these checked.


Hope you've got the upgraded nut on order.

[SutherlandFZS600]

Yeah well bought the bike last found this when stripping down a few month back and then educated myself with the known issue! Luckily shaft and threads were perfect show new sprocket and nut fitted! Sprocket was needing done anyway

[SutherlandFZS600]

Along with as you say genuine yam updated nut and washer

[Tefer]

Did you just do front sprocket, do you know what mileage the chain has done, i'd be tempted to do it all?

[SutherlandFZS600]

Yeah the whole lot has been replaced since taking pics, was short on pennies at the time and after pay day she was spoilt then

Possible stupid question alert but just double checking, is buying this one from wemoto ok (correct part number) or should I be going to Yamaha to be charged a lot more money?

No Harry. Go to yamaha, the sprocket nut upgrade is to cover their ass. As such it's offered to us foccers as a special kit at a knock down price. You do however need to provide the right code- see pic

I'd go to Yamaha, think its about £6 max.

Still cheaper at Wemoto delivered then, £5.47p.

[celticdog]

have a look at the picture, it's £2.44

You can start here, or just use the search part above and type in "front sprocket nut".

So then Mr SutherlandFZS600
Is your bike a 98 or a 99
also how many miles
Did the front sprocket have an orange plastic bit on it
Do you know if the sprocket has been changed in the past 

[SutherlandFZS600]

I believe mine to be a 98 fazersharp
Front sprocket did not have any orange plastic bit on it
I'm unsure if it has been changed or if that was the original sprocket.
Why are you asking all this anyway?

[bandit]

The original front sprocket had a orange centre so it has been changed at some point in the past.

Its because i have a theory that the 98 FZS does not suffer from the famous sprocket nut issue, but it has to be an factory fitted oem one to rule out any bad fitting by someone else. So when you post with a 98 saying your nut has come off I want to see if it is a factory fitted one that has failed, but no it looks like I can chalk up another 98 that is in the clear and another 98 proving my theory.
Search here for Sprocket Nut and you will find my posts 

[SutherlandFZS600]

Ah right yes I see what you mean! Yeah there was no orange damping disc on when I changed it, but it was still the older 9mm nut that was on there

[HarryHornby]

REEEEEESULT, spoke to my local Yamaha steeler.  If you give them the individual part numbers it's £15 for the nut and washer.  If you give them the part number in the picture near the top of this thread........


£2.60!!  BARGAIN!!


Cheers guys, top advice as always!

[SutherlandFZS600]

Glad you got a good price mate! Can't mind what I paid now but anyway glad it's sorted
