the 11 cost me £55 as the reciept is on the box, drop me a pm if you think it will fit yours
Yeah - the numbers make sense. I would have been interested in at least one of these as a spare - but after spending about an hour last night on the yamaha website I suspect that the F/J letter is important - still not sure what it is for possibly the exhaust or splines configuration. So thanks anyway.
