Here's what I figured out for my rear YFZ shock. The ride height was much too high for my taste. I cut off the bottom fork and redrilled the hole and adjusted the top mount like many others have but I went a little farther. Back when I had my YFZ (read: before it was stolen) I ran a stock rear conversion with a dual spring kit.
For those not familiar with this style of dual or multi spring setup, the top spring is nothing more than a tender spring to keep the lower seated. It fully compresses and bottoms out on the crossover at ride height. I've cycled the suspension and I'm coming out at just over 10" of wheel travel.
For the upper bolt I used an a-arm pivot bushing and ground down the outside diameter to fit the upper frame mount. I then cut off two peices to center the top of the shock in the upper shock mount on the frame.
Here is an exploded view of my shock showing the lower spring seat and retainers, dual springs, cross over, and of course the shock body with trimmed lower fork.
And finally an assembled shot of the shock. I drilled out a threaded coupler simply to add a somewhat finished look to the lower mount.
