[Water Warrior 2]

Hope this helps for a DIY stand. Square tubing and a welder. The stand is slid under the bike under the frame. When the handle is pulled back and down the bike is lifted up. The handle must be positioned/welded on the stand to allow the stand to overcenter and come to rest with the handle on the floor.
You will have to do careful measuring for the bike. I had mine made up for a dirt bike with at least 2 times the ground clearance so my numbers won't work on a GZ. The frame of the stand must be wide enough for the handle to clear the foot pegs etc when you pull the handle down. This was really slick for maintenance and very portable when we took our dirt bike on a trailer to the Rocky Mountains for a few days. The stand would effortlessly lift a 250 lb bike. The GZ would be even easier due to less clearance and different measurements.
