TUNING 171 TUNING Suspension Introduction No area of machine adjustment is more critical than proper suspension tuning. An improperly tuned suspension will keep even the best rider from attaining the full benefit of his machine's ability. Match the suspension to the rider and the course conditions. WHILE TUNING THE SUSPENSION, KEEP THE FOLLOWING IMPORTANT POINTS IN MIND: If the machine is new, "break-in" the suspension with at least one hour of riding before making any setting evaluations or changes. The three major factors which must be considered in suspension tuning are RIDER WEIGHT, RIDER ABILITY, and TRACK CONDITIONS. Additional influences include the RIDER'S STYLE and POSITIONING on the machine. Before changing the suspension settings, test changing your riding posture or position to check whether it is the cause of the problem or not. It is a wise practice to adjust the suspension to suit the rider's strong points. If you are fast in the corners, adjust the suspension to allow fast cornering. Make setting changes in small increments. A little bit goes a long way, and a setting is easily over adjusted. front and rear suspension should always be • The balanced; when the one is changed, the other one • • • might need to be changed similarly. When evaluating suspension performance, the rider must make every effort to ride consistently and to recognize the effects of his input. Such things as changes in rider position and increasing fatigue may lead to incorrect judgments about necessary adjustments. When the proper settings have been determined for a particular track, they should be written down for reference when returning to the same track. Lubricate the bearings in the swingarm and UNI -TRAK® linkage after break-in and after every 3 races to prevent friction from affecting suspension performance. j Front Fork Front Fork Oil Capacity The fork oil capacity in the fork tube is adjustable. A change in the fork oil level will not affect the spring force much at the top of fork travel, but it will have a great effect at the bottom of it. When the oil capacity is raised, the air spring becomes more progressive, and the front fork action feels "harder" in the later stage of fork travel, near the bottom. When the oil capacity is lowered, the air spring becomes less progressive, and the front fork action • •
