For those of you who have not figured out how to adjust the rear shock yet, here's how I did it and it's very easy.
Remove the upper belt guard and you have a clear shot to the adjustment holes. Using your adjustment tool (the dealer gave you one with the bike, didn't he?) insert it into the holes with the handle extension in place. I used a wood chisel inserted in the extension handle for additional leverage. Push away from you to soften the shock and pull toward you to stiffen the shock. If you want to stiffen it, it may help to jack up the rear wheel to take some of the load off it. The dealer where I bought it couldn't figure out how to do it. He said to bring it back when I needed a new rear tire and they could adjust it for me then. I guess they were just not familiar with the Stryker. Livin' & Learnin'.
