When using the Yamalink, depending on your weight, you need a stiffer spring. The Yamalink really changes the rising rate of the shock and can bottom easily depending how aggressive you are. I set up two bikes for a recent trip with stiffer springs, both 15% stiffer, and at about 210 lbs, both of us experienced bottoming. Onoe ridden by an A enduro rider and one slo poke, me.
