Checked my front sprocket last year and found nut and shaft completely knackered. Contacted local dealer (Skellerns) they checked with Yamaha and, after taking a few measurements, agreed to fix the whole lot FOC! And this on a 12 year old 28k bike. The repair took longer than ideally i would have liked (about 3 weeks) but i was just amazed they agreed to do it. You also get a free oil and filter change out of it
.

If it ain't broke.......just tinker with it a little anyway!
