Thanks for the welcome, OK 2005 xt660x 12, 000miles, I've had the issue with the final drive nut so stripped and torqued back up to 110nm, within 2 weeks of local commuting it sounds like it's back again, any of you guys had the same problem??? Is there likely to be anything else causing it to come loose, any thoughts would be great as apart from doing a full strip to find out I'm a little stumped.
