FRONT SAG
• PLACE SLED FLAT ON LEVEL GROUND AND NOT ON DOLLIES OR A LIFT OF ANY SORT
• SET THE SPRINGS AT FULL SOFT IN THEIR ADJUSTER, #1 ON MOST HPG, OR BARELY LOOSE IN THE RETAINER ON THREADED BODIES. LIFT THE SLED OFF THE GROUND, SKIS JUST TOUCHING OR NO MORE THAN 1/4" GAP AND HAVE SOMEONE ELSE QUICKLY MEASURE FROM THE GROUND TO THE FIXED POINT OF INTEREST ON THE FRONT BUMPER. LET SLED DOWN EASY OR WITHOUT DROPPING HARD. REMEASURE. SET SAGE AS FOLLOWS
• -2" FOR SEMI AGRESSIVE RIDERS
• -1" FOR VERY AGRESIVE RIDERS
• SAG MEASUREMENTS ARE TAKEN WITHOUT A RIDER ON THE MACHINE
• IF YOU NEED TO RUN THE SPRINGS AT MAX PRELOAD FOR PROPER SAG YOU ARE A CANDIDATE FOR HEAVIER SPRINGS
CENTER SAG/LIMITER STRAP
• THE TAIL OF THE MACHINE MUST BE ON A SUITABLE SAFE STAND WITH NO WEIGHT ON THE REAR SUSPENSION OR TRACK
• IF YOU BOUGHT A DUAL RATE SPRING LEAVE THE ADJUSTMENT AS IS WHEN YOU RECEIVED IT AND SKIP THE FOLLOWING SPRING ADJUSTMENT STEPS. COMPRESSING THE TENDER SPRING IN A DUAL RATE SET-UP TOO FAR WILL CAUSE HARSHNESS ON THE STUDDERS AS YOU HAVE NOW COLLAPSED THE TENDER SPRING AND NOW RIDING THE MAIN SPRING
• TIGHTEN/LOOSEN THE SPRING PRELOAD UNTIL YOU ARE ABLE TO MOVE THE SPRING WITHIN ITS RETAINER, OR ADJUSTER, WITH MODERATE FORCE. IF ITS VERY HARD TO GET THE SPRING TO SLIP BY HAND THE PRELOAD IS TOO TIGHT. IF ITS VERY EASY ITS TOO LOOSE. THIS IS YOUR BASELINE RELATIVE TO YOUR LIMITER STRAP SETTING
• LIMITER STRAP SETTINGS MUST BE ADJUSTED WITH CARE. THIS ALONE WILL CAUSE TOO MUCH OR TOO LITTLE SKI PRESSUE RESULTING IN LOSS OF CONTROL OF THE MACHINE OR TOO HEAVY STEERING. IF RUNNING THE FOLLOWING SKIS I SUGGEST THE FOLLOWING BASELINES. CASUAL RIDERS SHOULD NOT RUN SKIS OR CARBIDES THAT ARE VERY HARD TO TURN
-PRECISIONS ON REV- 2 HOLES SHOWING BELOW THE LIMITER ADJUSTER BOLT
-PRECISIONS ON A ZX OR CAT, POLARIS,YAMAHA -3 HOLES SHOWING BELOW THE ADJUSTER BOLT
-BRP FLEX SKIS/CA ADX'S ON REV 3 HOLES SHOWING BELOW THE ADJUSTER BOLT
-BRP FLEX SKIS/CA ADX'S ON ZX, CAT, POLARIS OR YAMAHA 3 HOLES SHOWING BELOW THE ADJUSTER BOLT
-AGRESSIVE AFTERMARKET SKIS LIKE CA RAZORS, OUTLAWS RUN 3 HOLES, THESE SKIS ARE GREAT BUT HARD TO TURN IN THE HARDPACK TWISTIES
THESE ARE ALL GOOD BASELINES BUT NOT THE RULE. RIDER WIEGHT, STUDS, ETC ALL PLAY A ROLE IN YOUR STEERING.
REAR SAG
• THE MACHINE MUST BE FLAT ON THE GROUND WITH NO RIDER ONBOARD
• LIFT UP ON THE REAR BUMPER UNTIL IT LOCKS, MEASURE TO THE BUMPER FROM THE GROUND, LET GO. THE MACHINE SHOULD SAG NO MORE THAN 2" UNDER ITS OWN WEIGHT. IF IT GOES 3 OR 4, GO UP 1 CLICK ON THE REAR TORSION SPRING ADJUSTER, REMEASURE. -0- SAG OR LESS THAN 2" IS GREAT!
• NOW SIT ON THE MACHINE, THE MACHINE SHOULD SAG NO MORE THAN +4" OF YOUR INITIAL MEASUREMENT. IF IT’S MORE THAN THAT THEN INCREASE SPRING PRELOAD TO ACHIEVE PROPER SAG WITH RIDER SITTING ON MACHINE.
NOTES OF INTEREST
• TOO MUCH SKI SPRING PRELOAD WILL CREATE A HARSH RIDE THROUGH THE HANDLEBARS,TOO LITTLE AND BODY ROLL WILL OCCURR
• TOO MUCH CENTER SPRING RELOAD AND THE RIDE WILL BE HARSH IN YOUR MIDSECTION,TOO LITTLE AND THE FRONT END WILL BE HEAVY TO STEER AND THE SHOCK MAY BOTTOM OUT
• TOO MUCH REAR TORSION PRELOAD AND THE RIDE WILL BUCK YOU OFF THE SEAT! TOO LITTLE AND YOU WILL BLOW THROUGH THE AVAILABLE TRAVEL IN YOUR SUSPENSION
• "FAT" SIDE DOWN ON THE REAR COUPLERS ON SKIDOO SC2,3,4,5 GIVES MORE SKI LIFT AND FULL REAR TRAVEL,LESS SKI PRESSURE. "FAT" SIDE FACING THE REAR OF THE SLED OR PARALLEL TO THE RAILS ADD’S SKI PRESSUE BUT REDUCES TRAVEL IN THE REAR SUSPENSION WHICH MAY SOUND BAD BUT IN CERTAIN CONDITIONS IS FAVORABLE.
• AVOID PULLING THE LIMITER STRAP TO 1 HOLE SHOWING BELOW THE ADJUSTER BOLT. YOU HAVE NOW REDUCED THE TRAVEL IN THE CENTER SHOCK BY 33%! NOT GOOD! IF MORE SKI PRESSURE IS NEEDED TRY ADDING 1/4" THREADS OR 1 CLICK OF CENTER SPRING ADJUSTMENT AS A TIME
• AFTER EACH ADJUSTMENT ABOVE RECHECK OTHER ADJUSTMENTS PREVIOUSLY MADE,SOMETIMES GEOMETRY CHANGES WHEN ADJUSTING THE REAR SUSPENSION
• SOME SHOCKS AFTER SERVICE MAY APPEAR TO BE LEAKING OR MOIST. THIS IS RESIDUAL OIL TRAPPED IN THE LARGE BODY SLEEVES OF SOME HPG SHOCKS THAT IS HARD FOR US TO BLOW CLEAN. THE OIL WEEPS OUT ON ITS OWN AND EVENTUALLY DIRES UP
C36 RACE SHOCK AND CLICKER TYPE ADJUSTMENT PROCEDURES
• ALWAYS SET UP YOUR SUSPENSION BEFORE ADJUSTING ANY CLICKER OR COMPRESSION, REBOUND ADJUSTER. WHEN YOU RECEIVE YOUR SHOCKS BACK FROM SERVICE THE CLICKERS ARE ALWAYS SET FULL SOFT. LEAVE THEM THERE UNTIL YOU RIDE THE SLED FIRST,THIS WAY YOU HAVE YOUR BASELINE
ON A C36 SKIDOO RACE OR CONSUMER SHOCK THERE ARE 2 COMPRESSION ADJUSTMENTS AVAILABLE. A 17MM RED NUT AND A SMALL BRASS FLAT HEAD ADJUSTER. ADJUST AS FOLOWS:
• -ADJUST RED NUT FOR HIGH SPEED PISTON VELOCITY HITS AS IN STUDDER BUMPS AT A HIGH RATE OF SPEED OR MASHING MOGULS. GO 1/2 TURN PER STAGE,LESS DOES NOTHING
• -ADJUST THE BRASS FLAT HEAD SCREW FOR THE SLOW SPEED PISTON VELOCITY AS IN SIT DOWN PLUSHNESS AND LONG SLOW ROLLERS. WHEN YOU TURN THE RED NUT THE BRASS SCREW WILL TURN TOO. DONT WORRY, THEY ARE SEPERATE WITHIN THE CLICKER. GO 4 CLICKS PER STAGE, LESS DOES NOTHING.
• KNOB STYLE SINGLE COMPRESSION ADJUSTERS NUMBERED 1 THROUGH 8 USE #1 AS FULL SOFT AND #8 AS FULL HARD. GO 1 CLICK PER STAGE,2 MAX.
• REBOUND ADJUST CLICKER HPG FRONTS ARE ADJUSTED BY TURNING THE SCREW. TURNING IN WILL SLOW THE REBOUND OF THE SHOCK AND STIFFEN IT A HAIR. GO 3 CLICKS PER STAGE
