so being the nice fella I let him have mine I'd bought to replace my 9mm standard one!
£2-44 from Streetbike, Halesowen, Yamaha main dealer for collection from them. This is the official Yamaha price.
Noob question. But whats the benefit in changing the sprocket nut?
think I paid over £16 for them for my FZ6, that was at Jax in York had to order them and pick them up, no postage on it.
