5 - Re-tighten the axle nut (5) securely
and tighten fixing nuts (6).
5- Recheck the chain slack after
tightening, lubricate and adjust if
necessary.
!
WARNING !
- Excessive tensioning of the chain
will put additional load on the
components of the secondary drive
chain (chain, bearings and rear
wheel). Aside from resulting
premature wear, chain may rupture
or transmission countershaft may
break.
- On the other hand, too much slack
in the chain can result in chain
jumping off the chain wheels. If this
happens, chain could also block rear
wheel or damage the engine.
- In either case, operator is likely to
loose control of the motorcycle.
Drive chain maintenance
A good maintenance is very important
for long chain life. Chains without o-
rings should be cleaned in fireproof
solvent regularly and afterwards treated
with hot grease or chain spray. On the
other hand, o-ring chains are very
simple to clean. The best way is to use
lots of water but never use brushes or
cleaning liquids. After letting the chain
dry completely, use a chain spray to
lubricate it.
Also check sprockets and chain guides
for wear and replace if necessary.
! CAUTION !
When mounting chain master link
clip, the closed side of the master
link must point in the running
direction.
! WARNING !
No lubrication should be allowed to
reach rear tyre or rear brake disc,
otherwise road grip and rear wheel
braking effects will be strongly
reduced and the motorcycle can
easily get out of control.
BRAKES
Brake pads

brake provide an optimal combination
of power, brake performance and
lifecycle.
