The nut saga?


I used the kit (both sprockets and chain) and changed the gasket and washer (as the mighty Haynes told me to) but not the nut.


I feel there's a story behind this?

To cut a long story short, there are issues with original size 9mm front sprocket nuts, ie: they fall off, weld themselves on, strip threads, etc.


So it's in your best interest to replace it with the new 12mm nut and washer  kit, for peace of mind, and the recommended torque for the new one is 90Nm.


PLENTY of info on here bout it, just do a search above for "front sprocket nut" and fill yer boots. 


NOTE: Part number for the kit is [size=1em]90891-10124 and can be bought from Wemoto, Fowlers of Bristol or AJ Sutton, or any Yamaha dealer.[/size]

Ah! Well then, I do believe a quick purchase might be in order to avoid long term pain!


Merci beaucoup monsiuer!

They vary in price depending if you buy in a shop or online but they're only a few quid.


My nut welded itself on and was a bugger to get off, others have vanished completely and the majority of bikes have no issues at all, but it's certainly a peace of mind thing and a cheap one too.
