Toe-in measurement steps.

• Mark both front tire tread centers.

• Raise the front end of the machine so that there is no weight on the front tires.

• Fix the handlebar straight ahead.

• Measure the width [A] between the marks.

• Rotate the front tires 180 degrees until the marks come exactly opposite.

• Measure the width [E between the marks.

• Calculate the toe-in using the formula given below.

• Loosen the locknuts(tie-rod end) ® both tie-rods.

• The same number of turns should be given to both tie-rods ® right and left until the specified toe-in is obtained, so that the lengths of the rods will be kept the same.

• Tighten the rod end locknuts of both tie-rods.

Locknut(rod end):

A WARNING

• Be sure that both tie-rods are turned the same amount. If not, the machine will drift right or left even though the handlebar is positioned straight which may lead to mishandling and accident.

• After setting the toe-in to specification, run the machine slowly for same distance with hands placed lightly on the handlebar and check that the handlebar responds correctly. If not, turn either the right or left tie-rod within the toe-in specification.

• Recommend tire pressure

Front 30 kpa (0.30 kg/cm2, 4.4 psi) Rear 25 kpa (0.25 kg/cm2, 3.6 psi)

• Tire pressure below the minimum specified could cause the tire to dislodge from the rim under severe riding conditions. The following are minimum:

Front 27 kpa (0.27 kg/cm2, 3.9 psi) Rear 22 kpa (0.22 kg/cm2, 3.2 psi)

Front 250 kpa (2.5 kg/cm2, 36 psi) Rear 190 kpa (1.9 kg/cm2, 27 psi) When seating the tire beads. Higher pressures may cause the tire to burst. Inflate the tiers very slowly and carefully. Fast inflation could cause the tire to burst.

1. Measure:

• Tire pressure(cold tire pressure) Out of specification Adjust.

The low-pressure tire gauge (D is included in the standard equipment. If dust or the like is stuck to this gauge, it dose two measurements on the tire pressure and get the second reading.
