MAINTENANCE
Toe Alignment Adjustment
If toe alignment is incorrect, measure the distance between
vehicle center and each wheel. This will tell you which tie rod
needs adjusting.
NOTE: Be sure handlebars are straight ahead
before determining which tie rod(s) need adjustment.
To adjust toe alignment:
• Hold tie rod end to keep it from rotating.
• Loosen jam nuts at both end of the tie rod.
• Shorten or lengthen the tie rod until alignment is as
required to achieve the proper toe setting as specified in
Method 1 or Method 2.
• IMPORTANT: When tightening the tie rod end jam
nuts, the rod ends must be held parallel to prevent rod
end damage and premature wear. Damage may not be
immediately apparent if done incorrectly. See
illustration 2.
• After alignment is complete, torque jam nuts to
specification.
Exhaust Pipe
The exhaust pipe must be periodically purged of accumulated
carbon as follows:
1. Remove the clean out plugs located on the bottom of the
muffler.
2. Place the transmission in Park and start the engine. Purge
accumulated carbon from the system by momentarily
revving the engine several times.
CAUTION
During tie rod adjustment, it is very important that the
following precautions be taken when tightening tie
rod end jam nuts. If the rod end is positioned
incorrectly it will not pivot, and may break

WARNING
• Do not perform clean out immediately after the
engine has been run, as the exhaust system
becomes very hot. Serious burns could result
from contact with exhaust components.
• To reduce fire hazard, make sure that there are no
combustible materials in the area when purging
the spark arrestor.
• Wear eye protection.
• Do not stand behind or in front of the vehicle
while purging the carbon from the spark arrestor.
• Never run the engine in an enclosed area.Exhaust
contains poisonous carbon monoxide gas.
• Do not go under the machine while it is
inclined.Set the hand brake and block the wheels
to prevent roll back.
Failure to heed these warnings could result in serious
personal injury or death.
