ADJUSTMENT S T E E R I N GF:O R K Through usage, theforkbearings mayloosen. Proper adjustment should allowtheforkto pivotf reely withthe tire heldoff the ground.The forkshouldneverrattleor movevertically in the headtube.lf proceedas follows: adjustment is necessary, '1. Loosenheadlocknutwith largepliersor largeadjustable wrench. 2. Tighten the innernutuntilthereis no looseness remaining, buttheforkstillrotates easilyand insidethe headtube. smoothly 3. Tightenheadlocknut.Re-check forkfor properadjustment. 4. lf furtheradjustment is necessary, repeatprocedure. DRAGLINK LINEARS withunderseat steering havea zeroendplayfeatureincorporated intothe draglink to prevent any looseness or playin the steering. Thisfeaturemay needadjustment fromtimeto time. Adjustment is accomplished by simplyturningthe nylontippedset screw(foundon eitherendof the (seephoto#13)clockwise draglink) to tightenthemuntilall playis removed. The steering shouldbe checked to insurethatit stillpivotsfreelyafterthe adjustment.
