Total cost of the part including vat is £4.20 ( In store today ) Unfortunatley the Yamaha FOC replacement campaign has long finished.

Thank you for your enquiry about your Yamaha FZS600.
The service note you have mentioned relates to a service check of the torque of the front sprocket nut.
If your motorcycle has ever had a replacement chain and sprocket set, the fitting technician will have re-torqued ok.
I hope this information is of assistance.
Best regards,

My reply
[font=]Thank you for your reply but I’m more concerned about the actual suitability of the front sprocket nut as mine is only 9mm wide(original) and I’m lead to believe by several other people that Yamaha have found this nut to be inadequate and hence replaced it FOC with an upgraded 12mm nut and gearbox output shaft when required. I’m aware as you say the new nut is fitted with a higher torque setting but as mine is not the upgraded 12mm nut I feel that over tightening it may actually do more harm than good. At the moment mine seems fine but as ignoring it could lead to serious engine damage I’m anxious to get it resolved.[/font]

Hello Andrew,
The nut for the front sprocket has a different part number mentioned as it comes in a kit with the tab washer. The nut in the kit is the same as the standard. i.e no change.
I hope this information is of assistance

So according to Yamaha the nut has never changed? obviously wrong. I know I could just change the nut but I'm concerned if I touch it and find anything else........... If I phone Yamaha who do I ask for and what do I say if they say nothings changed?
Sorry it's a bit long.
