two bolts (1) of the top triple clamp and

Steering head bearings should be
greased at least once a year.
! WARNING !
If steering head bearings are not
adjusted to be free of play or too
tight, the motorcycle will become
unstable and can get out of control.
Also they might be permanently
damaged.
! CAUTION !
If you drive with play in the steering
head bearings for long periods,
bearings and subsequently bearing
seats in the frame will be
destroyed.
Cleaning the dust sleeves of the
telescopic fork
The dust protection gaskets (1) are to
remove dust and coarse dirt particles
from the fork tube. However, after some
time, dirt may also get behind the dust
protection gasket. If this dirt is not
removed, the oil sealing rings located
behind it may start to leak.
Use a screwdriver to lever the dust-
protection bellows out of the outer
tubes and slide them downward.
Clean dust-protection gaskets, outer
tubes and fork tubes thoroughly, and oil
them with silicone spray or engine oil;
then push dust-protection gaskets into
the outer tubes by hand.
DRIVE CHAIN
Drive chain adjustment
The chain slack must be of 15-30mm,
at the mid point between the chain
buffer and the rear sprocket.
To adjust the drive chain, follow the
procedure bellow:
1 - Place the motorcycle on the side
stand
2 - Loose axle nut (1)
3 – Loose fixing nuts on both sides (2)
4 – Regulate adjuster screws (3) until
the chain has 15-30mm of slack. At the
same time that the chain is being
adjusted, the rear sprocket must be
kept in perfect alignment with the front
sprocket. Align both right and left
adjusters to the same position.
4 - Re-tighten the axle nut securely and
tighten fixing nuts (2).
