Hey Cam, howz it going and gidday from NZ nice bike mate, yep they were very quick but one thing to remember about the 250Z and D is check all your bolts after each Moto mate. They are fast but had a habit of shakn themselves to bits.
My flavour is white with a red seat, never got into the American YZ's, have a couple of pre 80 YZ projects in the garage, anyway good luck and talk again.
Cheers MC
