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.
• 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
