41.-CHain

The secondary transmission (chain, sprockets and guides) of your motorcycle
supports undergoes hard work. it is also one of the most important assemblies for
your safETy.
it requires constant maintenance and obviously, correct maintenance.
chain tension
1. motorcycle without load and with the side stand out: There should be a space
of 30 ~ 36 mm. between the chain and the swingarm in the rear area of the
chain guide. you can check with your fingers, but without overly forcing it.
2. Loosen the rear axle nut (1).
3. find the point of maximum tension on the chain.
4. using the nuts (2) of the tensioner, align the alignment of the chain on both
ends of the swingarm using the notches on the swingarm and the lugs on
the adjusters.
5. Tighten the nuts (2).
6. Tighten the nut (1).
7. check again at the point of maximum tension and re-adjust it if necessary.
The chain tension is a constant check. The state of the chain itself must be checked
visually, as well as the guide and the sprockets.
usually, when a chain is overused, or stretched more than 2%, it should be
replaced. usually this is the right time to change the guide, the front and rear
sprockets. This is for practical, economic and safETy reasons. a chain at the limit
of its use has partially worn the teeth rear sprocket, guide, etc. if you install a new
chain and do not change the other components, its life will be shortened by 40%
and the already-deteriorated elements such as the front and rear sprocket will reach
the end of their life quickly. in the medium and long term, the economic thing is to
change the complete transmission kit at each chain change. your official Gas Gas
service centre will gladly supply you with one.
Lubrication: its chain is of the type that has seals, this requires a special lubricant,
1
use the same lubricant for the guide, the chain guide shoe and the front and rear
sprocket.
note: We recommend you always have the chain correctly lubricated, those
chains that go dry, lubricated, dried, shorten their life and that of the components
that surround them to a significant extent.
42.-tireS
