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).
