Remove seat, pull up the plastic plate (has pop fasteners) move it out of the way, you can now see the shock and the ring which you turn (has numbers on it). Use the shock spanner wrench from you tool kit and turn the shock ring (not much room to do this) to a higher # for a stiffer ride or the opposite for a softer ride. Mine was on #5..I turned it down to #2 and it rides much more comfortable. However if you ride with a passenger you may what to take that into consideration.
Pull the seats and it's at the top of the shock where there is a key on the left side under the seat there is a tool kit with the wrenches to adjust it with I believe you go up with the numbe on the shock plate to get a stiffer ride
The adjustment is on the bottom of the shock turn counterclock wise to raise and clockwise to lower I find that the higher the better the ride
From 1 to 7 is it lift or right to make it harder
Can not get to it from the top!!! Going to try from the bottom see what happen.
What is your opinion on the number to put the back shock mind is number 5 with two of us on the bike it hit hard
