Troubleshooting
NOTE
For the
recommendations,
4 through
11,
to be most useful, the motorcycle must be adjusted as follows:
Forks- compression damping at standard position
,
at standard fork oil quantity and viscosity, and air pressure zero
,
Shock- nitrogen pressure
142
psi, compression
and
rebound damping standard
position,
and spring preload adjusted
so the bikes sags with rider seated
-
see Owner's Manual for spring preload adjustment.
Make only one change at a time, then test ride and evaluate the difference before making further adjustments. The
solu-
tions are given in the preferred sequence of adjustment
.
Possible
Causes
4. Front end oversteers; it cuts too sharply (such as in
sand):--------o~
·
Raise fork oil level
Use stiffer
fork
spring
5.
Front end understeers;
it washes out or pushes
-------------,o~·
Lower fork oil
level
(such as on a
tight
track with hard ground):
Use softer fo rk spring
6. Front end hunts at high speed; it wanders under power: __________
o_
·
Raise
fork
oil
level
Increase shock preload
7
.
Front end shakes under heavy braking:
- - - - - - - - - - - - - - - - _
.
Decrease shock preload
Increase
shock rebound damping
Raise fork oil level
8.
Front
end hops over bumps in smooth
turns:--- - - - - - - - - - - - , o o .
Lower fork oil
level
Decrease
fork
compression damping
Use
softer
fork
spring
9. Rear end hops over bumps white accelerating:
- - - - - - - - - - - - - _
.
.
Decrease shock spring preload
Decrease shock spring compression
damping
10.
Rear
end hops over bumps while braking:
---------------"0.
·
Decrease rebound damping
11
.
Rear
end
gets
poor
traction white accelerating away from a bumpy
corner:
_ '
Decrease shock spring preload
Decrease shock spring compression
damping
-
Whenever a solution says raise or lower
fork
oil
level,
do
so in increments of 5
cc (0.2 U.S. ozl and retest each time until you reach the maximum or
minimum.
If
the performance is still
unsatisfactory
and the next solution is to
install a softer or stiffer spring, return the oil level to the standard height and
begin testing
again.
Whenever an solution says increase or decrease damping (compression or
re-
bound!,
do so in increments of two clicks and
retest
each
time
until
you reach
the
maximum or minimum
.
If
the
next solution is
to
install
a
softer or stiffer
spring
,
return the damping adjustment to the "standard setting" and begin
testing again.
-
Whenever a solution says to increase or decrease shock spring preload
,
alter
the
race
sag by 2.5 mm (0.1 in) and retest each time until you reach the
max-
imum or minimum
.
