BASIC SUSPENSION SET-UP


Basic suspension set-up is very important in the overall performance of your suspension. Below are some helpful

steps you should follow to insure the components are installed properly and basic set up is correct.


















FORKS




When installing your forks torque the triple clamp pinch bolts to the manufacturer’s specifications (generally 15-16 foot lbs.) After you have installed the front wheel and slide the axle through, push down on the handlebars a few times to insure the axle lugs are seated squarely on the axle before tightening the axle pinch bolts. Improper installation can cause binding in the forks and harshness/stiffness in fork action.














HOT TIP



Factory Connection has installed an “O-Ring” on one of your Fork Sliders. This is a Free tool provided to help you gage the amount of fork travel you are using on your forks. First, Slide the “O-Ring” about half way up the slider, then after your ride, check the “O-Ring” position. This is an indication of how much fork travel you are using and will help you fine tune your forks softer or stiffer based on the “O-Ring” position!


 




SHOCK










When installing the rear shock, lift up on the rear wheel when tightening the shock bolt. Tightening extended can throw off your sag measurements. After installing the shock be sure to set your rider sag and check your free sag. The diagram to the right and instructions are to help you complete the procedure correctly.


The diagram to the right shows the sideloads placed on the shock body and shock shaft (red star). As a shock is used the piston o-ring(s), piston band, seal head o-ring and shaft guide bushing will begin to wear. As these parts wear out, shock damping deteriorates and excessive wear can create bigger problems such as damage to the shock body and/or shock shaft. This excessive wear is more often than not caused by lack maintenance.


RIDERSAG

MeasurementA : Place bike on a stand, wheels un-weighted;

measure from the left inside fender bolt to a point on the rear axle.



Measurement B : With the bike off the stand, place the rider w/gear on

the bike in a normal riding position with feet barely touching the ground. Have someone measure between the same two points as before.



• Measurement A - Measurement B

Remember these are only “General” recommendations. Different riding styles, tracks and manufactuer brands may vary these set-ups. However, listed below is a good starting point to choose from:

65cc ............. 70-75mm

85cc ............. 85-90mm

125-650cc ..... 100-120mm


If Factory Connection has re-valved . . . check the starting point section of this pamphlet for the recommended rider sag measurement.



Too much rider sag indicates you must increase pre-load to the spring by turning the Spring/Pre-load Adjuster clockwise.

(decreases rider sag measurement).



Too little rider sag indicates you must decrease pre-load to the spring by turning the Spring/Pre-load Adjuster counter clockwise.

(increases rider sag measurement).










 





FREESAG

Measurement C : With the bike off the stand and the rider off the bike; push down on the back end and let the bike come up by itself. Measure between the same two points as before.



Measurement A - Measurement C (Generally 25 - 35mm)

If you set your rider sag and your free sag does not fall within the recommended range; a spring change may be needed.



HINT: Less than 25mm generally indicates a stiffer spring is needed and more than 35mm indicates a softer spring is needed.




NOTE: 1" = 25.4 mm
