Thanks Pete, for your advice. I'll give that a crack - it might help me find the gear when I'm in traffic but clearly it's a fault if you have to do that. Do you reckon pulling apart the clutch and putting it back together would reset the alignment? Or is it more complicated than that, i.e. defective component / clutch rebuild?

My bike should still be under warranty, so I'd like to be armed with a bit of knowledge of what is causing the problem before i hit Yamaha up and they brush me off and tell me it's just a wear and tear issue.
