Checking Tire Lateral Runout
1. See Figure 2-29. Turn wheel on axle and measure
amount of displacement from a fixed point to tire side-
wall.
2. Check tire tread for appropriate runout specification. See
Table 2-9. If runout is more then specification, remove
tire from rim.
3. Check rim bead side runout. See 2.7 CHECKING CAST
RIM RUNOUT . Replace rims not meeting specifications.
4. Install tire and check again for tire tread lateral runout.
Checking Tire Radial Runout
1. See Figure 2-30. Turn wheel on axle and measure tread
radial runout.
2. Check tire tread for appropriate runout specification. See
Table 2-9. If runout is more then specification, remove
tire from rim.
3. Check rim bead runout. See 2.7 CHECKING CAST RIM
RUNOUT . Replace rims not meeting specifications.
4. Install tire and check tire tread radial runout again.
ADJUSTMENT
Wheel Balancing
Wheel balancing is recommended to improve handling and
reduce vibration, especially at high road speeds.
In most cases, static balancing using WHEEL TRUING AND
BALANCING STAND (Part No. HD-99500-80) will produce
satisfactory results. However, dynamic balancing, utilizing a
wheel spinner, can be used to produce finer tolerances for
better high-speed handling characteristics. Follow the instruc-
tions supplied with the balance machine you are using.
NOTE
If the rear wheel on the XB9R will not fit on a stock dynamic
spin balance shaft, use the Carlson wheel balance shaft (Part
No. AF15).
WEIGHTS FOR CAST WHEELS
The maximum weight permissible to accomplish balance is:
● 1.0 oz. (28 g) total weight applied to the front wheel.
● 2.0 oz. (56 g) total weight applied to the rear wheel.
Wheels should be balanced to within 1/4 oz. (7 g) at 60 MPH
(97 KM/H).
See Figure 2-31. Use only WHEEL WEIGHTS (Part No.
43692-94Y) which have special self-adhesive backings.
Apply WHEEL WEIGHTS to the flat surface of the wheel rim.
1. Make sure that area of application is completely clean,
dry and free of oil and grease.
2. Remove paper backing from weight. For additional adhe-
sive strength, apply three drops of LOCTITE SUPER-
BONDER 420 to adhesive side of weight.
3. Locate a flat surface on the right side of the wheel rim
and press weight firmly in place, holding for ten seconds.
4. Allow eight hours for adhesive to cure completely before
using wheel.
NOTE
If wheel assembly is out of specification (1 oz front, 2 oz rear)
rotate tire and rebalance until wheel is within specification.
