So, if you have a triple tree stand that you used on previous bikes but haven't got around to trying on the Z, guess what? The hole in the bottom of the stem is 27mm! None of my normal sized pins fit, largest being 17mm. What I did was get a large diameter thick washer with a 17mm I.D. and 36 mm O.D. to put over the pin, then used a 1/2" drive 19mm socket (which is 26 mm O.D) to help center the thing for security. And watch the cute little point on the bottom of the headlight when lifting. It's always something.
