Was there anything that would have gone under this rubber strap when the bike was new, looks like it would be for the tool kit except that's down by the light? Also what are the two loops either side of the metal tab? All they seem to do is squash things I put in the under seat storage, I've half a mind to cut them off, but thought I'd check their purpose first.

I found the tech bulletin where Yamaha accept the problem and advise dealers to change to nut, but I notice that they only think there was a problem with '99 models onwards, if I had said it was a '99 and not a '98 would I have got a different answer from the guy on the parts desk I wonder?


I also noticed that the bulletin was issued by Yamaha USA, were the UK dealers similarly notified?


I'll go down the dealers and see what response I get claiming it's a '99 model, and then order the part number in the ebay listing anyway.

So it seems to be a thing! After hearing a noise, I removed the front sprocket cover to find the nut just sitting loose on the end of the shaft, not a hint of thread left in it. I bought a new nut from the dealers and came on here looking for a torque figure for it, turns out its a common fault and that most people, including Yamaha, know about an upgrade to a wider nut.


So how come my dealer in Carshalton sold me a 9mm nut and claim no knowledge of any other part, the dealer in Twickenham also claims ignorance, and even Yamaha UK say there is only one part number suitable for a my bike and that's for the 9mm nut I've been given?


Despite all the related threads on here I couldn't find a part number mentioned for the 12mm nut, is it a genuine Yamaha part?
