[SOLVED] Drive Sprocket Nut and Lock Washer Replacement bulletin

[keratos]

Does this mean I can take the bike to any Yamaha franchise dealer and request them to inspect and replace? The bulletin states "regardless of warranty". Or, are there conditions that need to apply or something I need to do before a dealer will do this work?  i.e. does the bike need to be in for a routine service? I've just bought the bike from an independent shop who "serviced" it but did not examine this nut

forget it - I've just read the bulletin - fully - replacement will only be done at routine maintenance, PDI or trade in of an incoming bike
