The third and top bolt is located in the rear swing arm, you'll need to pop the weather covers off using a small pry bar or srewdriver to get access to this bolt.

Align the bolts, you may need to use a pry bar or lift the rear swingarm/wheel to get them all aligned, be careful not to force and damage the threads. Thighten all bolts and replace the weather caps.

The front can be lowered slightly to level the bike, there may not be alot of adjustment and the forks will simply bottom out at the end of adjustment. I was only able to lower them by a few mm.

Loosen the two bolts on the fork brackets to allow adjustment.

Holding the front brake and pushing down and forward should be enough to get them to slide for adjustment, once the desired height (or bottomed out), retighten the bolts and your away

The bike still handles and rides the same, only I am now able to have better contact with the ground, helping dramatically on hills and uneven ground.

Here is a good video of the installation using the Yamalink

On every lowering link with an increased leverage ratio, be sure to reset sag in the rear. Depending on the amount of lowering, you may have to turn in the rebound to help slow down the return of the stored energy. Proper torque of the 17 and 19mm nuts is crucial, same with the forks, remember to properly torque the bolts. Too tight and binding will occur which can cause to excessive stiction.
