�had my XT660z (2008) valves done this week, for the first time, at 30,426 miles old, they didn�t need adjustment. This seems a testament to the quality of the XT660z engine; robust and longevity.

...or the fact, as I found, that Yamaha set them too loose in the first place!

Just me that made a mess of doing them up then? :-)

I adjusted mine when I should have left them alone.

They sound a bit rattly after a thousand miles but I'm not up for taking it all apart AGAIN!
