Steering

Handlebar and the steering stem & bearings: the settle-and-retorque bearing procedure (39 N·m seat → 4.9 N·m final), stem-head nut 108 N·m, handlebar fitment, stem removal and warp check.

Steering exploded view: 1 handlebar clamp bolt (O, S), 2 handlebar holder nut, 3 steering-stem head nut, 4 upper fork clamp bolt, 5 steering-stem nut, 6 lower fork clamp bolt (AL). O = apply 2-stroke oil, G = grease, S = follow the tightening sequence, AL = tighten clamp bolts alternately twice, Lh = left-hand thread.

O = apply 2-stroke oil to the threads · S = follow the tightening sequence · AL = tighten clamp bolts alternately twice.

Caution

The steering-stem nut is a two-step torque, not a single value: first seat the bearings at 39 N·m, then back off and set the final 4.9 N·m. Skipping the seating step leaves the bearings loose (head shake) or, if you simply torque to 39 N·m and leave it, notchy steering. Use Steering-Stem Nut Wrench 57001-1100.src: Kawasaki VN2000-A1 Service Manual — Periodic Maintenance (Torque & Locking Agent / Specifications tables, pp. 2-7…2-13)

Switch housings, master cylinder and grips off; refit with the clamp bolts oiled and torqued.

Handlebar

  1. 1

    Remove the headlight upper cover, then the clutch-lever assembly and left switch housing, and the front-brake master cylinder, right switch housing and throttle grip.

  2. 2

    Unscrew the clamp bolts and lift the handlebar off the stem head.

  3. 3

    On installation, apply 2-stroke oil to the clamp-bolt threads and torque the clamp bolts (follow the sequence).

    Torque34 N·m
  4. 4

    Fit the right switch housing so its locating projection enters the small hole in the bar; set the left switch housing and clutch-lever assembly to the bar’s punch mark; refit the master cylinder (see Brakes).

The full stem job, centred on the 39 N·m seat → 4.9 N·m final bearing-settle sequence.

Steering-stem (head-bearing) adjustment: A = the steering-stem nut, B = the stem-nut wrench (57001-1100). Seat the bearings at 39 N·m, back the nut off, then set the final preload at 4.9 N·m so the stem turns smoothly with no play. Over-tight steering is dangerous — re-check for free movement and no rattle.

Removal

Remove the front wheel first.

  1. 1

    With the front wheel off, keep the rear wheel on the ground.

    Warning

    Be sure the rear wheel is on the ground when removing the steering — otherwise the motorcycle may fall, causing an accident and injury.

  2. 2

    Remove the headlight unit & cover, front turn signals, the brake hose clamp and the stem cover; remove the handlebar clamp & assembly, the stem-head nut & washer, and the forks (see Suspension).

  3. 3

    Remove the O-ring and stem head, the claw washer, then the steering-stem nut (wrench 57001-1100), the oil seal and the lower O-ring, and pull the stem out from the bottom.

Installation & bearing settle

Grease the needle bearings; fit the stem, bearing, a NEW O-ring (I.D. 34.5 × 2 mm), stem cap and stem nut.

  1. 1

    Seat the bearings: tighten the stem nut to 39 N·m (hook the wrench and pull 218 N at the 180 mm hole), then loosen it.

    Torqueseat 39 N·m
  2. 2

    Retighten the stem nut to the final torque (pull 27 N at the 180 mm hole).

    Torquefinal 4.9 N·m
  3. 3

    Fit the claw washer, push the fork legs up tight against the stem bottom and temporarily tighten the lower clamp bolts; fit the stem head, O-ring, washer and head nut and temporarily tighten the upper clamp bolts.

  4. 4

    Check the inner-tube top is flush with the stem-head upper surface, then tighten the upper fork clamp bolts, the stem-head nut, and finally the lower fork clamp bolts (AL).

  5. 5

    Adjust steering, throttle cables and headlight aim, then check front-brake effectiveness before riding.

    Warning

    Do not ride until a firm lever is obtained by pumping the brake until the pads contact the disc.

Whenever the stem is out — or if the steering cannot be adjusted to turn smoothly — check the stem for straightness and replace it if bent. If either stem bearing is damaged, replace both upper and lower bearings with their outer races as a set, grease them on installation, and check afterwards that the stem turns smoothly with no play or rattle. Replace the stem cap if its grease seal is damaged.src: Kawasaki VN2000-A1 Service Manual — Periodic Maintenance (Torque & Locking Agent / Specifications tables, pp. 2-7…2-13)

Pressing the head-pipe (steering-head) outer races home with new races greased: A = the head-pipe outer-race press shaft (57001-1075), B = the head-pipe outer-race driver (57001-1077), which drives the upper and lower outer races into the head pipe together. The inner races are then driven onto the stem base with the steering-stem bearing driver (57001-1344) and adapter (57001-1345). Always renew both outer and inner races as a set.
Kawasaki VN2000-A1 Service Manual, Steering “Stem Bearing Installation” (p. 14-11).
Steering-stem straightness check: A = the steering stem (the shaft pressed into the lower bracket). Whenever the stem is out — or if the steering will not adjust to turn smoothly — check the stem for bend; if it is bent, replace the steering stem. Do not attempt to straighten and reuse it.
Kawasaki VN2000-A1 Service Manual, Steering “Steering Stem Warp” (p. 14-10).
Handlebar switch-housing alignment on installation: A = the left handlebar switch housing, B = its mating surface, C = the punched mark on the handlebar — set B to C before tightening so the controls sit square. The handlebar clamp bolts and holder nuts are tightened to 34 N·m (oil on the threads). The clutch-lever holder is aligned the same way, mating surface to punched mark.
