Please Note:
This information is taken directly from the Coyote Service Book, as supplied with the bike. I have removed a couple of bits of information that are irrelevant to the XC2.

1. IMPORTANT NOTES

It is imperative to adhere to the instructions prescribed in this manual. FASTRAX and COYOTE strongly reccomends that service be performed by an authorised dealer, with proper equipment. Failure to comply may result in improper installation, causing injury, and voiding warranty.

If the shock ever loses oil or if it makes sounds of excessive topping out, stop riding the bicycle immediately and have the shock inspected by a dealer. Continuing to ride with the shock in either of these conditions could result in loss of control of the bicycle with possible serious and/or fatal injuries.

2. TUNING YOUR REAR SHOCK

By matching the proper spring rate and damping adjustment, Fastrax shocks can be tuned to your particular weight, riding style and terrain.

When tuning suspension, always make one change at a time and write it down. This takes patience, but allows you to understand how each change affects your ride. Keeping a record lets you know what changes you have tried that work and suggests what changes you might try.

3. RIDE HEIGHT ADJUSTMENT (SAG)

Sag is the amount of shock travel that is used up as the rider sits stationary on the bike. Proper sag determines the bikes ride height and is taken in conjunction with the front fork. This sag allows maimim tyre contact with the ground when riding over rough and uneven terrain. You will find average that you will use approximately, one third of the shocks travel, when you sit on the bike. This will normally lower the bike by around 50mm.

1. To adjust the sag, turn the threaded spring collar away from the spring and stop turning just as the spring feels loose in the shock. This is zero pre-load.
2. Without sitting on the bike, measure the distance from the floor to the stem (front height) and floor to the seat (rear height). Write them down.
3. Then with a friend holding you while you sit in a normal riding position on the bike. Measure those same distances. The difference between to two measurements is your sag.
4. To start, the sag for the front and rear should be the same.
5. If the suspension sag is less than your bike manufacturer's reccomendations, a softer spring rate is required. If the sag is greater than reccomended, then turn the threaded collar to decrease the sag until it is correct. Use a stiffer spring rate if you reach the 2.5 turn limit. Do not exceed 2.5 turns of the threaded collar.

4. SPRING RATE CHANGES (CHANGING THE SPRING)

To fully utilise your rear suspension your shock should occasionally bottom out. Check for bottom out while riding fast over aggressive terrain. Bottoming out is a condition when all suspension travel has been used up. If you are bottoming out too often or not enough the overall spring rate should be changed. If you bottom out too often, choose a stiffer spring rate or if you never bottom out, choose a softer spring rate. To change the spring rate follow the instructions below to remove the spring.

1. Remove the shock from the bicycle.
2. Clean the shock body threads.
3. Turn the threaded spring collar towards the body eye, removing sag (pre-load) from the spring. Then remove the spring retaining collar from the spring. REMOVE THE DAMPING ADJUSTMENT KNOB WITH A 2MM HEX WRENCH.
4. Remove the spring.
5. Install the new spring. Then reinstall the retaining collar and damping adjustment knob.
6. Set te sping pre-load (see "Ride Height and Spring Pre-load Adjustment")

5. COMPRESSION ADJUSTMENT

The SL shock includes a compression damping adjustment knob. The knob permits fine tuning of the shock's rate of compression. The compression is quickest when the adjustment knob is in the full counterclockwise position and slowest when in the full clockwise position.
