New owner here. I've just bought a 1999 Fzs 600 that's only done around 4000 miles. I've not passed my test yet (start training on the 23rd) so I'm using the time to fettle it a bit (not that it needs much) Just freeing off a sticky front brake piston and re-painting the main stand so far. On the advice of a forum member, I pulled off the drive sprocket cover and checked the drive sprocket nut. Its a 9mm thick nut. There's no sign of movement between sprocket, lock tab and nut. I'm pretty sure its the original chain and sprockets. So do I get a new 12mm thick nut and change it now or wait until I need a new chain/sprocket set and do it then?
